DIY aeg punch repair

In detail: do-it-yourself aeg perforator repair from a real master for the site my.housecope.com.

Even very reliable Makita rotary hammers break down over time.
Any breakage is eliminated, you just need to have straight arms and perseverance.
In addition to electrical malfunctions, rotary hammers are also susceptible to mechanical damage.
Operating rock drills with hard materials in a dusty environment will shorten the service life and require user intervention to perform preventive maintenance.

Any tool repair begins with determining the nature of the malfunction and disassembling.

The Makita 2450 and 2470 hammer drill can be repaired by a user who has basic locksmith skills and is familiar with electrical safety requirements.

This article discusses the mechanical part of the Makita rotary hammer, the main malfunctions and how to fix them.

Dismantling the mechanical part of the Makita 2470 rotary hammer

To get to the mechanical part of the hammer drill, you need to remove or disassemble the cartridge.

Dismantling the quick-release chuck
Place the punch on the rear case cover on a tabletop covered with a clean cloth or paper. Using tweezers or a screwdriver, remove the rubber tip 35, item 1.

Carefully loosen the annular spring, pos. 2, the coupling cover, pos. 3, and the steel ring, pos. 4. You will reach a steel ball with a diameter of 7 mm pos. 20.

Now you can remove the housing of the mechanical part
It is black.
Using a screwdriver, unscrew the four screws at the end of the case.

Holding the black case with your right hand, press your thumb on the end of the shaft from which the cartridge was disassembled. The plastic housing can be easily removed.

Next, you need to remove the gearbox shaft.

To disconnect the mechanical part from the electrical one, you must first remove the electric brushes.
Remember! In the lower part of the housing, the rotor is held by electric brushes, which must be removed.

After checking that the electric brushes are disconnected from the rotor lamellas, use a screwdriver to pry the metal housing of the hammer drill at the border of the green plastic housing.

Video (click to play).

Now we turn to disconnecting the rotor from the mechanical part of the perforated

ra. The rotor is held mechanically by the helical gears of the reducer.
If you take the rotor housing in one hand and the mechanical housing in the other and pull in different directions, swinging, you will separate these two units.

You will get such a unit in the old grease.

Then unscrew with a hexagon two bolts M4 × 12, pos. 43., art.266273-7 with an internal hex head.
Pull out the shaft with the intermediate spur gear 10 pos. 80, art. 226399-7.
from the inner case, pos. 49, art. 153687-8. Remove old grease from parts.

You will get such a mountain of clean details.

Now carefully look through the details, discard the rubber rings immediately after picking up new ones.
Replace the defective parts with new ones.

Frequent mechanical failures of Makit punchers include:

destruction of the quick-release chuck;
failure of bearings;
breakage of the striking mechanism;
drill barrel wear;
wear of striker and striker rubber bands;
breakage of gears.

The hammer drill chuck is repaired to replace the boot and rubber ring, as well as the conical spring and the steel ball, which secures the working tool (drill). This is indicated by what is a working tool? namely, the drill does not hold well in the chuck.

The main reason is the wear of the steel ball 7.0, item 20, art. 216022-2. The wear of the ball occurs from contamination of the bore of the cartridge due to the ingress of dust and dirt.

The general view and device of the Makit perforator cartridge is shown in the photo below.

Do-it-yourself repair of the makita 2450 perforator cartridge is easy.The cartridge must be disassembled, freed from old grease, discarded rubber parts, replaced defective.

More complex malfunctions require knowledge of the mechanical part of the Makita 2450 perforator.

Having determined the nature of the malfunction of the Makita perforator, proceed to disassemble the mechanical part, called the gearbox.

Disassemble the mechanical part according to the attached video.
Free it from old grease.
Carefully inspect all parts, their integrity, level of wear. All rubber products require replacement during any disassembly.

Consider repairing the barrel of a rock drill. Let's analyze the mechanism completely.
Video of disassembly, lubrication and assembly of the Makita perforator

Remember! In the lower part of the housing, the rotor is held by electric brushes, which must be removed.

The next step is to disconnect the rotor from the removed mechanism. The rotor is simply disconnected from the mechanism by pulling it out, since it is held by the friction of two helical gears.

The result is such a dirty knot.

Now we need to separate the percussion shaft.

Most often, rubber rings, firing pin pos. 24, compressor spring pos. 18. and cylinder parts.

This is how barrel parts wear out and break down when the tool is misused.

Consider the most difficult malfunction - the failure of the striking mechanism.
The characteristic signs of a breakdown of the percussion mechanism are the absence of a blow and the unpleasant noise of a working perforator in the "Blow" mode.

Such a malfunction is typical for those rotary hammers that, during operation, were strongly pressed against the surface to be treated.
Having disassembled the gearbox, we remove debris and pieces of foreign objects. We find the faulty part and clean everything from the old grease.

Very often, the firing pin pos. 24, art. 324396-8, which is part of the barrel.

metal ring pos. 27. art. 324216-6.

Discard damaged parts, replace with new ones, cover with a thin layer of grease. The parts are ready for assembly. But more on that in the next article.

They threw out at work the perf, seemingly killed in the trash, all in fuel oil, sand and with a cord cut off at the root. Another screwdriver is the same, but about him later. I pulled it home, the stator windings rang, both 2.7 Ohm, only the plastic insulation was slightly melted. Well - I think if the same resistance means whole ... The anchor didn’t even ring the bell. everything looks OK with him, clean without darkening the insulation ... In general, I decided to build up the wires and plugged it into the outlet ... WORKS!

Dick if he was thrown out, I thought)))) I decided to disassemble it completely and clean it ... How I started at home, in the bathroom ...) I immediately cleaned all the plastics from the case, then began to half it, I could not make it out for about 40 minutes. all the bolts were under a centimeter layer of black fuel oil ... I downloaded the diagram for it:

And I found a couple of bindings hidden under a layer of mud. I cut it in half and oh ... ate ... I did it like half the case, and the bathtub is already dirty))) I thought I wouldn’t play with my wife’s nerves, I’ll wash the gearbox in the garage. And he began to scrub the tub of powder.
The next day I drove to the garage with an armyinby
He chopped his car, and I cleaned everything of coke in a hammer drill and helped him along the way: he hung in the garage
In general, how I cleaned everything up. I got to collect it) I came home and let's pick everything up according to the scheme)) Here is a photo:

Audi A4 Avant 2004, diesel engine 1.9 l., 130 l. sec., front-wheel drive, variator - DIY repair

my AEG is 14 years old (I killed 5-7 perfs from competitors, but I just bought new cartridges). And here the other day the blow disappeared (that is, when the button is pressed weakly, it hollows, and when completely it disappears). I decided to figure it out and got into a dead end (I can not remove the lower switch). rummaged through net, did not advance a single step until I came across your Oleg schemes (I'm sure they will come in handy). If it doesn't make it difficult, tell me how to remove it (I don't want to break it, because in our LPR I only think of such a device) When I drove a car from Szczecin (Poland), I bought this German there. By the way, there are three more differences to the schemes 261 262 276 ...

Honestly, I don’t remember how I ripped it out, but I remember that I suffered with it. But I didn't seem to break it) The recordings have been for almost a year, but the perf works as it should.

why are these entries in the BZ car?

Why in BZ cars of chicks with naked asses are photographed?

there at least in the background of the car
Soon people will start writing cake recipes in the BZ))

Why do you have in the BZ: Photoset at a gas station, Club card Volkswagen Technical Site (VWTS), Reviews about ZIC 5w30 oil, Summer PhotoSeason_2015, "Teaser" and most importantly: Help with answers (temporary entry) which has been hanging for 2 years)) ) Keep track of your BZ. If you don't like mine, just don't litter comments, no one asks you to climb here)

How easy it is to hook you!
Calm, and again calm! And it was not too lazy to watch my BZ.
If you don't want to read other people's comments, turn off the ability to write them.

So I'm calm) As they say, you can reach the post. It's just that it's more interesting for me to describe an independent repair here, even if it is a washing machine, a perforator or something else, than hammering BZ with the same type of assemblies of pictures of the car in different places and taking pictures of girlfriends with naked asses)) In reality, at least with this I want to diversify my BZ, especially spinning in the garage. And with recipes you go too far 😉

May be )))
In any case, honor and praise to you for the work done 👍🏻

Anyone who has ever had to work with a hammer drill knows how difficult its operating conditions are. That is why do-it-yourself punch repair is such a popular request on the Internet. And today we will tell you absolutely everything regarding the repair of this tool.

Undoubtedly, the owners of such expensive equipment want their devices to be of high quality, to do their job 100%. First of all, correct use of the tool will save you from serious damage, which we will talk about a little later. And, of course, the device was repaired on time. At the same time, any small failure should already become a cause for concern and preparation for repair.

So, such "beacons" can be:

Unstable work of the punch in the working mode;
The appearance of strange sounds when turning on the punch;
The smell of burning;
The hammer drill does not hammer, although there is no apparent reason for this.

As soon as something like this happens to your equipment, it means it's time to repair. Like any such work, it requires care, understanding the cause of the breakdown and knowledge of how to cope with it. And your very first step in repairing is disassembling the tool into its components. For many, even this stage causes difficulties, and therefore it is necessary to know everything down to the nuances - how, what and why!

Just imagine that your tool suddenly stops working or you urgently need to replace any defective part. The easiest way is to take the hammer drill to a service center for repair, but this takes time, which means it will stop your work for a while. But if you know how the device is disassembled, it will be much easier for you to carry out the rest of the work. In addition, this will lead to significant cost savings, because there will be no need to spend money on paying for the services of repair centers.Instructions for parsing the tool:

We start work, starting from the upper unit: first, the rubber tip is removed, then the washer, the spring, the ball finishes working.

After you have removed the ball, we unscrew the screws that hold the case, remove the cover on the handle, if available, and lastly disconnect the stator wires.

We remove the brush holder.

The next step is to separate the gearbox and housing until a gap forms. It is through it that we will retrieve the switch.

After that, the punch body is placed vertically, with the help of a vise, it is fixed, and all its parts are carefully removed from the device.

Whatever breakdown awaits you, clean the case - sometimes it is dirt and dust that prevent the device from working normally.

The most common malfunctions in machine components are:

wear of brushes;
breakage of the start / stop button.

In this case, the above problems may be accompanied by:

unstable work;
extraneous noises and sounds;
the smell of burned wiring;
inability to work in a given mode - crushing / drilling.

The reason for disassembling the tool is the dilapidated state of the boot of the cartridge. To avoid this, you only need to work with long drills in the future. However, the problem is not always in these details, and so that you can understand the nuances of repairing this device, in the article we will tell you what can be useful to you in this matter.

Cleaning and lubricating the rubbing parts of the mechanism is possible only when the device is completely disassembled, which, in order to avoid major breakdowns, should be carried out regularly. It is necessary to disassemble the device from the upper assembly of parts. First you need to remove the rubber tip. When you do this, you will see the lock washer. After removing it, the head and spring are removed. Take out the ball. The disassembled parts are best folded into a separate container prepared in advance so as not to get lost. The procedure for opening the case must be carried out after opening the gap in the case by at least five millimeters. The switch handle should be in the hammer drilling position, then it can be safely removed. Then you can remove the case.

One of the most expensive and costly parts in the repair of a hammer drill is the so-called anchor. These are copper coils interconnected and bonded by lamellas. In the event of a violation of the insulation of copper wires, a short circuit and a breakdown of the wiring occurs, therefore, the entire part of the engine must be replaced.

Complete disassembly of the gearbox is a necessary procedure to diagnose problems with this assembly. After dismantling the plastic housing, removing the remnants of the old grease, you will have to disconnect the following parts:

floating bearing;
drive gear shaft;
raster sleeve;
sleeve with a piston.

The floating bearing is fixed in the aluminum housing with a metal bracket. It should be wrung out with a flat screwdriver. Then you need to take out the bearing and replace it if necessary. In the design of the floating bearing there is also a needle one, which is necessary for the rotation of the drive gear. He has to experience great overloads, and, as a result, he often breaks down. You can buy it either as a set or separately from the shaft.

An impact bolt is fixed in the grid sleeve by means of a metal impact ring. The ring is accessed through two side holes. A steel striker is located inside the bolt. It is advisable to replace the sealing rubber bushings, which are necessary for the tightness of the mechanism. In the process of replacing the parts of the striker, it is necessary to grease abundantly.

This model is famous for its short-lived collector. Often overheats, a pungent plastic smell appears. Breakdowns are common. Strong vibrations, noise. Differs in a large mass.Brushes need to be changed frequently. The design has some minor usability flaws. The on / off button burns out easily when it gets jammed. Bearings need to be changed frequently. The gearbox fails occasionally. The lubricant is constantly flowing, there is a strong overheating in the "jackhammer" mode, especially during intensive work.

Dismantling the mechanical part of the Makita 2470 rotary hammer

To get to the mechanical part of the hammer drill, you need to remove or disassemble the cartridge.

Dismantling the quick-release chuck
Place the punch on the rear case cover on a tabletop covered with a clean cloth or paper. Using tweezers or a screwdriver, remove the rubber tip 35, item 1.

Now you can remove the housing of the mechanical part
It is black.
Using a screwdriver, unscrew the four screws at the end of the case.

Holding the black case with your right hand, press your thumb on the end of the shaft from which the cartridge was disassembled. The plastic housing can be easily removed.

Next, you need to remove the gearbox shaft.

After checking that the electric brushes are disconnected from the rotor lamellas, use a screwdriver to pry the metal housing of the hammer drill at the border of the green plastic housing.

Now we turn to disconnecting the rotor from the mechanical part of the perforated

You will get such a unit in the old grease.

Then unscrew with a hexagon two bolts M4 × 12, pos. 43., art. 266273-7 with an internal hex head.
Pull out the shaft with the intermediate spur gear 10 pos. 80, art. 226399-7.
from the inner case, pos. 49, art. 153687-8. Remove old grease from parts.

You will get such a mountain of clean details.

Now carefully look through the details, discard the rubber rings immediately after picking up new ones.
Replace the defective parts with new ones.

Frequent mechanical failures of Makit punchers include:

destruction of the quick-release chuck;
failure of bearings;
breakage of the striking mechanism;
drill barrel wear;
wear of striker and striker rubber bands;
breakage of gears.

The main reason is the wear of the steel ball 7.0, item 20, art. 216022-2. The wear of the ball occurs from contamination of the bore of the cartridge due to the ingress of dust and dirt.

Hello everyone! Today, when chiseling, I began to throw oil out of the AEG reducer (something there) superX, which has a capacity of 1024 watts. , do not bother with repairs (I gave it once, on Sladochnaya Street, repairs cost money), but buy instead? I really want a really reliable perf.
PS: in some branch, someone argued, they say, AEG-unkillable, so I have a Kress 750 with 97g. is still alive and has never been repaired, and after a year the AEG was repaired - it began to work in slotting mode with simple drilling).

Should I fix the AEG hammer drill again, or buy another one?

Buy ANOTHER AEG, new

My AEG stopped a month after the purchase. The guarantee was refused - replacement of the brushes. Rhetorical question: How did the brushes in the expanded AEG in normal operation run out of service in a month? True, they took money only for the brushes, the replacement work is free. After that (t-t-t) everything is all right. So the AEG label means nothing at all, lottery, mlyn.

Hilti 12S has more than twenty years of experience and even without changing brushes.
By the way, on the punch, on the body, you can see numbers to know the depth of the hole. I don't remember if there is such a feature in other models.

In general, the AEG instrument has deteriorated. I have a parquet floor and two shura

Now I looked at the analogue AEG-Milwaukee, the protection against vibration, it vibrates strongly, the fix-stack cartridge is also not very good, the cartridge began to fall out of this fixture. Probably, I will buy Divolt D 25113 K, cheap and angry

PS: I wanted Makitka, but something went down with the quality.

the chuck with the chisel just fell out of the quickfix several times

Strange and highly doubtful. This cartridge is as simple as a felt boot. Very reliable.
