There are a lot of comments from the series “I don’t do every little thing” or “if the service manager travels on requests, then he’s a loser,” but I have a completely different opinion on this, it seems to me that repair has long ceased to be just a job for me and has become way of life.
I immediately remembered a recent Samsung washing machine with a similar problem, checked all SMD components and came to the conclusion that the reason is in the inductance itself.
I bought a new one, but due to the carelessness of me and the seller in the store, the denomination was not the same, I don’t think the power is of fundamental importance, but it was not the same, so after installing it, the malfunction repeated itself and ruined the mood.
“Naduraka” put the inductance from the Arcadia power supply, which is in our store and lo and behold, everything works, but it feels like the rpm is a little lower, which I could not measure and it is not known what they should be, but I still ordered from China a set of different inductances, let them be.

A meat grinder is simply an irreplaceable device for grinding different types of meat. If earlier most housewives used manual machines, now more and more users prefer electrical devices. This is not surprising, because the electric meat grinder grinds meat of any quality in a matter of minutes, saving the hostess' time and effort.
Unfortunately, all electrical appliances tend to break down, and repairing them is somewhat more difficult than manual ones. This article will tell you how to repair a meat grinder at home, and what you can do with your own hands.
Manual meat grinders are made entirely of mechanical parts. When disassembling, it is always easy to see the breakdown and replace the damaged part with a new one. Moreover, all the components are easy to find on sale.
There is nothing special to break in manual-type meat grinders. Most often, they have dull knives that can be easily sharpened with a fine grinding wheel. Such a circle is put on the axle of the meat grinder instead of a mesh for the output of products and rotary actions are performed with a handle, as when grinding meat.
Occasionally, a strong squeak is possible when the device is in operation. Then you should disassemble the mechanism, grease the place of rotation of the handle so that the grease does not get to the meat container.
All parts of hand-held devices are made of metal and cannot break if sinewy pieces or small bones hit, since a person will definitely feel the tension at hand and clean the mechanism. The exception is modern manual meat grinders, made of fragile metal.
All electrical meat grinders, regardless of manufacturer, consist of:
engine;
gearbox - consists of several bearings and gears for transferring the power of the motor to the rotational movements of the cutting mechanisms;
knife systems (auger);
control unit;
power cord.
The main reasons for the failure of all brands of electric meat grinders is their improper use. Only a small percentage depends on poor build quality. The quality of the parts themselves depends on the reliability of the manufacturer. It is not worth saving on it, since repairs can be much more expensive, and it is not so easy to find parts on sale.
The most common malfunctions of meat grinders:
the device does not turn on at all;
the meat grinder turns on, but the disc does not grind the product;
the drive works, but does not gain the required number of revolutions;
you hear fumes or smoke during operation;
increased extraneous noise or knocking, which were not previously noticed.
Not always, with the slightest breakdowns, you should take the device to a service center, where it can successfully lie for many weeks, and you will have to pay decently for repairs.
If the meat grinder does not turn on at all, the cause of the breakdown may be in the absence of contact or a malfunction of the control panel.
Disassemble the device by unscrewing all necessary screws. Sometimes the plastic parts of the case snap together, then you should find all the grooves and snap them VERY CAREFULLY. Otherwise, the case may be damaged, then it will not be possible to fold it back. An example of the case disassembly can be found in the pictures of the "SCARLETT" model disassembly.

SCARLETT meat grinder disassembly diagram: get the gearbox
Check all the contacts, the connection of the power cord to the device, maybe something needs to be twisted or soldered.
If the meat grinder turns on, but the auger does not grind the product, the reason may be a faulty gearbox. Bearings could have crumbled or gears could be worn out from a heavy load or hit by bones.
In this case, disassemble the relay, check all parts for defects. Whether the gears scroll easily, are all the teeth present, are there any extra backlash when moving. Switch on the disassembled device without loading the auger.
Do this carefully so that all parts do not fly to the sides and something does not interfere with the operation of the engine!
Do not forget to photograph or memorize the location of the parts, so that later you do not puzzle over what to put where.
Relay breakdowns are the most common reason for a meat grinder to fail.
If the cause turned out to be defects in the gears (which is very likely, since they are made of plastic), the damaged parts should be replaced with new ones. It is not so easy to find new gears on sale, they are not sold separately for most models. You may have to contact local services to buy the necessary used part from another device or try spare parts from other models.
In some rare cases, the cause of the auger turning interruptions may be the wear of the socket for its fastening or the misalignment of the shaft. This can occur from a constant increased load on the device or improper manufacture of a socket from a metal that is too soft. Loosening of the auger and licking of rotary mechanisms is a very big problem. To eliminate it, you will need the help of specialists.
If the grinder is working, but not picking up the required speed, most likely an overload has occurred. This problem is most common in Kenwood mg devices.
The device should be disconnected from the power supply, disassembled, cleaned and cut the meat before serving into the meat grinder in smaller portions.
The main reason for extraneous noise, knocking in the operation of devices is the ingress of unnecessary objects inside: small bones or veins. They can get stuck and clog the joints between different parts of the appliance. Also, on insufficiently washed parts after previous use, food particles can dry out and cause blockages.
In such cases, the device should be disassembled, cleaned, and all foreign objects removed.
Sometimes the cause of extraneous noise and sharp sounds in the operation of the electric meat grinder can be crumbled bearings. They are easy to find on sale and replace.
If you hear fumes or smoke from a working meat grinder, most likely the reason is engine breakdown.
To repair the motor yourself, you will need some knowledge of electrical engineering, the direction of alternating current, adjusting the operation of a synchronous and asynchronous motor. If there is no such knowledge, it is better to immediately contact the service center. But, at the same time, the importance of repairs should be appreciated.
The cost of repairing a motor is usually very high, so sometimes it is easier to buy a new device under warranty than to repair an old one.
If you have certain knowledge, it should be borne in mind that both spirals of the electric motor winding are offset from one another by 90 degrees. In the second winding, the currents differ in phase. As a result of this difference, the rotor starts. The difference in currents is created by the capacitor. It is used to provide the initial acceleration of the rotor.
Electric meat grinder motor and rotor
The motors for household electric grinders are asynchronous. In them, the rotor speed lags behind the stator magnetic field. A damaged capacitor can be the main cause of a grinder breakdown.
If the capacitor is damaged, it should be replaced with a new one.
When buying, pay attention to the capacity and voltage rating.
If one of the windings is burned out, the motor must be rewound.
In any case, before repairing a meat grinder at home, you should evaluate your strength and knowledge so as not to aggravate the breakdown.
I don't really care. there the speed of revolutions became a bit different))
We drank the bat at the end, and unscrew it with a minus screwdriver
As an option, but it's still probably better to fork out
Here are three sets that I myself use and they complement each other and are very high quality, some of them have been since 2000 - kraftool 25611-h12 and kraftool 25616-h12. And for large jobs, Wiha's timeless bits are the wiha xselector standard 7944-904. Bits are indestructible, screwdrivers are very tenacious. Threat VC99 is a dull slow tester, mastech 7032 is much better, I have both and I use only mastech at home. IMHO. And almost any automatic multimeter, without a choice of measurement ranges, will be slow.
If for the whole table, then of course some kind of linoleum is better, on a thick foam base, but you can also fork out for a silicone mat, with compartments for screws, it is very convenient for disassembling all sorts of small things. Like these:
There is one, but so far I rarely use it
It was interesting to see. Meat grinders with a smooth start have not yet come across to me. And I liked the handle of the blue screwdriver too. +
Thank you, good luck with the repair, we will definitely test the screwdriver and write our fi
Hi Sanya! For convenient repairs, I advise you to lay a small polik on the table for the trunk (or for the rear passenger) seats of the car. The collars do not allow small parts to fall on the floor, devices, boards, etc. do not slip on rubber. After work, garbage, unnecessary parts))) you can shake and polish to wipe or wash. It can also be used for repairs on any surface that you do not want to get dirty or scratched, i.e. mobile thing repair!
Oh, thank you very much, I will definitely try, the idea is very good
Friend, excuse me, stop lowing, and also a brother on business, always ready to help a person
I try to change this in myself, but so far my brains are working hard to scribble words without hesitation, so I mumble like a cow
As always, thanks for the informative video 🙂 On the topic, I have long faced that I need normal TORX screwdrivers, and with a hole in my chin, I bought 5-6 years ago, too, for repairing small equipment .. and how many times he has already helped me out 🙂
A good tool will always pay off
Of course, if it is expensive, then you do not appreciate the work of a master, if it is not enough and you are a master yourself, then you clearly overestimate yourself, but this is just my opinion
Instead of long bits, an L-shaped torx, it gets there where you can't crawl with a normal bat, I bought a set for 60 rubles, I use it for a year
A shitty tool in my opinion, normal metal cannot be so cheap, but if price is more important to you than quality, then it is sold for you in the store, otherwise I keep thinking to whom they carry it, now I know, thanks
690r .. is this the total total cost for the entire service? this made little Bosch MFW 1501
SW19 please tell me the number of the ball bearing of the gearbox.
strange question but why so few.
advice: - do not take comments close to your heart, you should not be sprayed and waste your valuable energy on envious people and similar vague contingents. ))));
I will reveal a secret no reason to start
Put a carpet on the table and the glass cases will not fall !! fine-bristled

Inductance for a hundred millinewtons? How do you fix something else with such knowledge.
And after reviewing the moment a couple of times, I got into the comments, looking, they say, maybe someone also noticed, otherwise I will be the first, God forbid, they will say - “they say the most intelligent?” And they will beat you. )))
I thought from the beginning to write that a reservation, but then I thought that anyone would understand, I still had to write))))
I dined slowly and profitably. Thank you.
Recently, I have been taking component tester in the store, I randomly check it, often even the store is not aware of the quality of the goods. On the linoleum option, you don't need to turn it over, just take a commercial ordinary household one staggers and very quickly.
Ok, we will definitely do it on our hands

For half an hour it can be seen from the banal replacement of the drosel, this is a tin! This is a sore in the Boshes, which everyone has known for a long time and has been discussed more than once on the forum and on YouTube!
Hardening of what, find at least a word about the hardened paws of the pulley puller, they were specially made massive and solid so that they would not burst, therefore it is not potassium, although there is no problem in this, but the fact that you broke something is not a problem in the tool , because you will break a red-hot one, and you will bend a raw one, because first you need to think with your head, and then pull from your heart, and you have everything from your soul to your soul
SW19 Club of Masters of Household Services and where does he fit tell me? A familiar craftsman removed the pulley from a Samsung engine, your puller had an arched grip. Where is your vaunted hardening of the tool?
The notch corrected the situation only with the boshes, for all the others it just came up and continues to come up, and you got into the head because you were sent nuts on a stock, not a closed, but an open type, which is why you had to send two nuts in a separate package , which would suit you and it would be fine if these nuts played at least some role other than aesthetics, now the version has no nuts at all, but you decided to be principled and climbed on your horns, and now you look like an offended little girl and by offended I understand exactly insult, not thieves' concepts, But thanks for the comments anyway, I hope you liked the new gadgets, I tried to choose them more beautifully

Do-it-yourself electric meat grinder repair, causes of breakdowns and malfunctions.
Experts refer to the schemes of electric meat grinders as simple options, but for the layman, even they can turn out to be difficult. Typically, an electric grinder breaks for the following common reasons:
- Improper care. This is a poor sharpening of cutting knives. Because of this, an additional load is created on the engine and the electrical network of the device, due to which over time it breaks down;
The electric motor of the meat grinder burns out due to the fact that condensation forms in it. It is simply impossible to list all the reasons why this can happen. For example, a new device was brought from the cold and immediately connected to the network, turned on. The electric motor will immediately burn out due to the formation of condensation on the stator windings.
In order to avoid breakages, it is necessary to monitor not only how sharp the knives are, but also behind the bars. They should not be clogged with tendons from meat, and if this happens, then timely cleaning is required. Such correct operation will help to exclude more complex breakdowns, for the repair of which it will be necessary to disassemble the device and work with circuits.
Electric diagram of a meat grinder (without additional elements)
If the malfunction is such that the meat grinder needs to be disassembled, then you should know how to do it correctly. The explanations in this part of the article relate to the moments when the electric motor of the device or the capacitor failed.
Two windings of the electric motor are offset relative to each other. The offset is equal to 90 degrees. In the second winding, the currents differ in phase, and due to this difference, the rotor is started. The difference in currents between the two windings is created by the capacitor. This means that the current value for one winding will always be higher than for the other. A capacitor is needed in this electrical circuit in order to ensure the initial acceleration of the rotor.
The electric motor of the described household appliance is asynchronous. This means that the rotor speed lags behind the rotation speed of the stator magnetic field. If, when disassembling the device, it is found that the capacitor is faulty, this is the main reason why the device does not turn on.
How to choose a capacitor
The values do not have a tolerance in the deviations of the capacity of this part. Because the deviations will be minor. An important characteristic is the capacitance of the capacitor, as well as the nominal value of its voltage. When the correct part is selected, then to repair the device, you just need to replace the old capacitor with a new one.
If the electric motor burns out
The engine needs to be replaced again. But here you need to watch that the price of a new part is not higher than the price of the meat grinder itself. When such a situation arises, it is better to buy a new electric meat grinder with a free service guarantee. You can see the cost and range of electric motors in the store, in the radiator department.
Other possible malfunctions:
- Sometimes the device does not work due to the fact that there was a break in the mains cable at the very base of the plug. Here you just need to replace this part;
- Sometimes the cable can be damaged along its entire length, for repair it will be necessary to completely replace it with a new one;
In general, if there is no relevant experience, you should not go inside the device. Many problems can be fixed at home by a person who is at least minimally familiar with the principles of household appliances. But for the correct operation of the devices, so that it breaks down, the hostess will be able to keep track of herself.
The electric Zelmer meat grinder is, of course, more convenient in our household use in comparison with a simple mechanical meat grinder.
The electrical circuit of the meat grinder can be attributed to simpler circuits.
Zelmer electric meat grinder
As with every household appliance, the meat grinder has its own causes of malfunctions:
untimely care;
power surge;
mechanical damage
and other reasons. What can be attributed to untimely care? - Poor sharpening of the cutting edge of the knives is admissible. In this example, a load is created both on the electric motor of the meat grinder and on the electric circuit of the meat grinder, at which a malfunction of both the electric motor itself and the capacitor in the electric circuit of the meat grinder can occur.
You cannot name all the reasons at once. Let's say you bought a meat grinder in the winter, brought it home and plugged it in right away. In a warm room, condensation has formed on the stator windings, - you connected it and immediately the electric motor of the meat grinder immediately burned out. It is also necessary to pay attention to the correct use of household appliances.
The mechanical part of the electric meat grinder is shown in Fig. 1.
In general, no clarifications on this part are required. Timely you need to monitor the cutting part of the knife, as well as monitor the grate so that it does not get clogged with tendons from meat.
The photo shows the electric motor of the Zelmer meat grinder, - with a gearbox.
In this unit, the cause of a malfunction can be both a malfunction of the electric motor itself and wear of the gear transmission of gears.
Consider the electrical diagram of the Zelmer meat grinder without additional elements in Fig. 2, an explanation in this topic will be given to the main causes of malfunctions of the electric meat grinder, such as:
The two stator windings of the electric motor are offset from each other by ninety degrees. The current in winding B differs in phase from the current in winding A, due to this difference, the initial start of the rotor is ensured.
The difference in the currents of the two stator windings is created by a capacitor, namely, the current value for winding B will be greater than that for winding A. That is, the capacitor in the electrical circuit here serves to ensure the initial acceleration of the rotor.
The electric motor of the meat grinder is asynchronous, the rotor speed of which lags behind the rotation speed of the stator magnetic field.
Consider some of the causes of a malfunctioning electric meat grinder. For example, your diagnostics established a capacitor malfunction. How to choose the right capacitor?
The tolerance in the deviations of the capacitance of the capacitor is not important, since the deviations in the capacitors are insignificant. Important characteristics are the capacitance of the capacitor itself and the nominal voltage value of the capacitor.
The next reason for the malfunction is a burned out electric motor. With such a malfunction, it is easier to replace the electric motor itself, if the cost itself is more acceptable for purchase.
These parts are available from the radio store. If the capacitor you need is not on sale, the capacity of the capacitor you need can be selected from two separate capacitors, let's say two capacitors. In this example, to increase the total capacitance, two capacitors are connected in parallel.
Minor causes of malfunctions include:
break in the mains cable wire at the base of the plug;
break of a wire of a network cable along its length
A general diagnosis of all connections can be carried out - with a probe. Diagnostics of the electric motor is carried out with the Ohmmeter device or the Multimeter device, previously set to measure the resistance of the stator windings of the electric motor.
Household meat grinder BOSCH MFW1501 TYPE: SFW1 (Made in Slovenia) -The new meat grinder works for 5 minutes, does not overload, the meat is soft, cut into pieces, boneless, then a click and the engine rotates idle.After disassembly, it turns out that the crown of the large plastic gear is completely destroyed by the metal worm of the engine shaft. I change the gear to a new one, the same picture is repeated. Maybe someone knows how this problem is treated, otherwise these gears cost 500 rubles each and tell me how to lubricate this transmission mechanism. For clarity, attached
- power regulator, soft start and motor current control unit - THREE DIFFERENT devices according to purpose, sometimes wired into one “peak” and implemented in software. you just don't have it.
You see, as a repairman, I only see shitty meat grinders. then the engine is not to hell, then the mechanism is rather weak. You'd better ask about this topic here https://my.housecope.com/wp-content/uploads/ext/2254/section10/, can anyone boast.
Gear material is guano. It can also be seen that the teeth are melted. In appearance, this is the same plastic from which gears are made for Chinese mafons. So no lubrication will help here. Option number 1 - to repair the meat grinder and use it for a short time, so that the worm does not have time to get very hot. Option number 2 - to order the turner a gear made of durable heat-resistant material - then this rubbish will become a meat grinder. The degree of heating depends on the density of the material to be ground.

shov244 , yes, in the photo there is something.
Yes, we have “made you happy”. You see, it all started with the fact that I decided, as they say, to keep up with the times - to buy a modern silent meat grinder. Until now, I have used this one in the photo, it's terrible to say since 1992, produced by the Ural (western Kazakhstan) Zenit plant. I don’t know what’s inside, never even once. did not disassemble because there was no need. I used it at least once a month, but there were two troubles that made me buy a new one: 1. Knives were often blunt. 2. The noise during operation is such that it clogs up the ears. Nevertheless, thanks to everyone for the answers, the situation is, in principle, clear, I will think.

Auger bushings are different. Russian, Chinese and original. Is there really a difference between the original and a fake if the copied work belongs to the category of spare parts for a meat grinder. Indeed, even in the visual arts, a copy is so good that a canvas created during the Renaissance cannot be distinguished from a painting made by an "underground" master of the current postmodern age. But if you look at the bushings for the Bosch meat grinder, original and not original, then even on the basis of a hasty visual inspection of these accessories, you can find some discrepancies.
The first photo shows the auger bushing from a Russian manufacturer, the second one shows the original safety clutch from Bosch.
The color of the non-original product differs markedly from the classic element produced in factories in Europe. The original Bosch safety clutch has a neutral beige shade. Chinese and Russian manufacturers decided to create a brown beige auger sleeve for a Bosch meat grinder. Comparing to artists who can distinguish forty shades of the same color, we can say that the beige, represented by the screw fuse of Russian or Chinese manufacturers, is slightly diluted with brown, it does not have a matte surface, typical for the bushings of the German brand, but a glossy, shiny one. Hence another difference of the original screw sleeve from the non-original coupling in the meat grinder follows.
The sequence of arrangement of the original and non-original bushings is the same as in the photo above. For clarification: on the left - Russian screw fuse, on the right - German
The material from which the original Bosch meat grinder sleeve is made is plastic. But plastic is not ordinary, its main characteristic is environmental friendliness and the possibility of using it in a mechanism that comes into contact with food. During the operation of the meat grinder, the hostess puts pieces of meat in the neck (inlet), which, due to the rotation of the screw, move to the outlet openings of the grate. If you recall the name of the spare part discussed in this article (and it has many names: auger bushing, auger fuse), then it is logical to conclude: the products filled into the meat grinder come into contact not only with the auger, but also with the clutch. It is not known what raw material the Chinese safety clutches are made of. Probably, purchasing a Chinese or Russian analogue of a Bosch coupling, you risk a little. According to many craftsmen and engineers, Chinese manufacturers use raw materials that are not processed or intended for food purposes.
The third difference: the calculated parameters for torsion and material resistance.
These antennae "antennae" are the most sensitive part in the structure of the Bosch auger hub. In the event of an overload of the electric motor, it is they who break
Fourth difference: packaging.
Original packaging of the screw sleeve for the Bosch meat grinder
Pay attention to how the overload clutch is packed. A sealed bag, a label on which “ORIGINAL” is printed in yellow, means that you have been sold an original spare part for a Bosch meat grinder. Ordinary packaging in the form of cellophane, without any marks on it - you have purchased an accessory that cannot boast of its noble European origin.
So we figured out what is the difference between the original spare part and its Chinese counterpart. It is also necessary to clarify some of the subtleties in the structure of this miniature spare part in the Bosch meat grinder. Perhaps the auger bushing in your meat grinder has a bolt hole; new parts may not have this hole. This small feature will not affect the quality of the meat processing equipment. Recently, instead of a hole, manufacturers decided to put on a rubber seal on the fuse, which comes with the clutch.

Hello everyone. I ran into a problem, I have a Bosch MFW 1545 meat grinder that is broken, or rather a board. When I turn it on, the second voltage is supplied to the electric motor for a second and it is cut off, then it is turned on and again this picture. I brought it to the TV workshop there, and they gave it to the engine through a 30v lateral, workingExcellent. We checked the board and said that the simulator btb 12 600cw or the pic 16c621a-0417p microcircuit flew out. I bought the simistor, I changed the result to zero, the microcircuit at the bazaar was told that they would bring it, but it needs to be flashed, but they don’t know how and how much. The manufacturer writes that the power of the engine is 500 watts After reading the reviews on the Internet (I had to read it before buying), I realized that the gearbox in the meat grinder breaks down before the protection is triggered.

The electric assistant today is very popular and in high demand among Russian buyers. Despite high-quality manufacturing and high reliability in operation, electrical appliances tend to break down over time. Many breakdowns can be repaired at home, so we will tell you in detail about the repair of an electric meat grinder, which you can easily do with your own hands.
It doesn't matter what kind of meat grinder you have - Kenwood, Zelmer or Moulinex, each of them has its own nuances, but the faults are pretty typical for all. Electric meat grinder repair specialists have compiled the following register of the main problems encountered in these products:
violation of various contacts of the electrical circuit;
deformation of the engine rotor;
breakage of the teeth of the gears of the reducer - arises from the increased load;
malfunctions of the electric motor, extreme wear of the brushes;
wear of the cutting tool due to the processing of too stringy meat, the ingress of small bones due to the user's oversight;
breakage of keys, safety devices;
damage to insulation, power cord;
replacing the motor or rewinding its windings.
Many failures of reliable technology are due to violations of operating conditions and only a few - a factory defect or a human factor during assembly.
If any malfunction occurs, it is necessary to immediately carry out diagnostics in order to find out the cause and localize the breakdown. Inspection of the mechanical part of the product is carried out visually, and the electrical circuits are checked with special devices. If a visual inspection of all parts of the mechanical part did not give a positive result, then you need to dismantle the product and inspect the gearbox, electric motor. May have happened clogged lubricant rubbing parts, the bearings do not work correctly, they need to be replaced.
Timely diagnostics allows you to identify and eliminate malfunctions at an early stage of their development, which significantly extends the life of the entire product.
Let's consider in detail the malfunctions of the meat grinder and methods of their correction.
The engine does not reach the set speed - the reason may be broken switch or the engine itself. Replace worn mechanisms or an electric motor.
Interruptions observed in the drive - extreme wear of graphite brushes , you need to install new ones.
Extraneous sounds, burning smell during product operation - defective engine ... To restore it, you need diagnostics, repair or complete replacement. However, the cost of replacing the engine is quite high - it will be more cost effective to purchase a new grinder and solve the problem.
The reason for the appearance of sounds unusual for the normal operation of the meat grinder may be bearings that wear out during operation. To confirm the diagnosis, it is necessary to disassemble the main body of the product, get to the place of their installation and check the rotation, if necessary, replace it.
Reducing the speed of the electric motor - overload , the food is fed too fast, the meat grinder does not have time to grind them.The Kenwood mg model is especially susceptible to this problem. Reduce the feed dosage and everything is normalized.
No shaft rotation - the transmission mechanism of the reducer is seized ... One of the gears or its teeth may be broken and need to be replaced.
The product auger has stopped. If at the same time the engine is operating in the same mode, then turn off the meat grinder and dismantle its mechanical part in order to find out the reason.
In the latter case, there are several reasons for the occurrence of such an unusual failure: incorrect assembly of the gearbox, cranking of the motor shaft, breakage of the drive gear teeth, and very rarely licking of the connection by the auger shaft (erasure of the hexagon).
On a note! The non-conformity of the metal of the part leads to its failure during the ultimate load.
If the hexagonal receiver, where the auger shaft is inserted, is made by mistake of a softer metal, then during operation it quickly expands, or its edges wear off, the tight contact will be broken ... The same can happen with the auger tip. It is difficult to repair a meat grinder with such problems with your own hands; the help of professional repairmen of similar equipment is required.
