DIY KMZ light trailer repair

In detail: do-it-yourself repair of a light trailer kmz from a real master for the site my.housecope.com.

Hello! Today we will talk about, in my opinion, quite an interesting light trailer called KMZ 8136. This model belongs to the category of classic trailers, if I may call them that.

Modern production has taken a big step forward. But this does not prevent the KMZ 8136 model from remaining relevant and in demand until now.

There is still an active sale of a trailed vehicle. This is due to the high quality of factory products that were released in due time. You can buy such a light trailer rather on the secondary market. Although some still offer them in a new state. How much their statements are true is difficult to judge.

My task is to acquaint you with the features of KMZ 8136, tell you about its technical characteristics. I will not forget to mention the manufacturer.

The KMZ plant or Kurganmashzavod first produced its own light trailer in 1984. Then it was a multifunctional model of a fairly compact size. The products quickly gained popularity due to the affordable cost and high quality of the product.

The manufacturers have provided literally every little thing. High quality wheel bearing, shock absorbers, durable suspension arm and other parts were used. In order to change the silent blocks or other components, the owners did not have any special problems. For this, one did not have to seek help from specialists.

Currently, their old trailers, including KMZ 8136, are actively exploited and are being converted to the needs of the owner. Someone has a spring instead of a link suspension, others put larger wheels, digest the board, etc. This is a convenient and simple trailer that allows you to adapt it to various tasks and functions.

If we talk about modern production, then in 2017 the Kurganmashzavod plant underwent significant changes. It began to be used for the production of military equipment. But because of this, the production of caravans was not discontinued. Production was moved to the city of Cheboksary, retaining a team of experienced specialists and engineers. We also managed to maintain the entire production cycle.

Now KMZ trailers are produced at a new site. The specialists modernized the production base, which made it possible to improve the quality of products and reduce the cost of manufacturing equipment. Therefore, changes are not always for the worse.

If you don't remember or have forgotten, then we have presented the KMZ 8284 20 trailer and the KMZ 8284 21 model. We also provided a comparison of two popular solutions, determining the preferred trailer between the Krepysh and KMZ models. I advise you to read. It will be interesting and useful for you.

If you look at the official passport of this automobile light trailer, you can find out a lot of interesting and useful things regarding the original design of KMZ 8136. To begin with, I would like to note that this is a trailer for passenger cars, focused on the transportation of various goods. I hasten to remind you about the features and advantages of flatbed trailers, which you can read on the link.

The plant provides for the installation of a whole list of assemblies and parts, including shock absorbers, bearings and silent blocks, identical to those used on domestic cars. So, you can put on a trailer a set of wheels from VAZ or Moskvich. The exception is the Moskvich model M 2141.

The suspension here is very high quality and durable. It is an independent design with compression coil springs and telescopic hydraulic shock absorbers.Also, stamped-welded levers are used that swing in the longitudinal plane and are hinged with silent blocks on the transverse beam of the trailer frame.

It is now possible to choose and install springs on a passenger car without any problems, making almost everything you want from domestic classics.

From the factory, complete with KMZ 8136 came:

awning;
set of extension boards;
drawbar extension;
fasteners;
electrical kit for connecting lighting devices to the vehicle's on-board network, etc.

The package bundle was rich enough. Some components were offered for a surcharge, others were included in the base price. But the price remained at an affordable and adequate level, which largely explains such popularity.

I agree that in some modern KMZ 8136, which have gone through alteration and revision, it is difficult to recognize the outlines of a classic domestic trailer even from a photo. But nothing lasts forever, therefore it is required to improve and modernize the design. Even if initially KMZ 8136 has excellent quality.

Reading the reviews, I found that many cannot find the frame number on their KMZ trailer. I am in a hurry to help. Usually this number is located in the area of the left side lamp. Look in that area.

It often happens that during the operation the room gets dirty, erased or covered with new layers of paint. This is an obvious flaw on the part of the manufacturer, since the number was not duplicated on the 8136 models until 2000. It is located only in one place and is sometimes poorly visible due to the initially not very high-quality application.

If you figured out this, then it remains only to consider the main technical characteristics. Understanding the approximate dimensions and capabilities of the caravan, you can decide for yourself whether you need a similar option, or it is better to look among something more modern.

I will start from the passport data, considering the technical aspects of KMZ 8136. Let's start.

The carrying capacity here is 380 kg;
The curb weight must not exceed 170 kg;
The indicator of the total mass is 550 kg;
The manufacturer recommends adhering to a speed of no more than 90 km / h if KMZ 8136 is included in the road train;
Trailer length 3060 mm;
With the drawbar extension installed, the length increases to 3860 mm;
Overall width of the trailer is 1760 mm;
The height here is 1010 mm;

I suggest you draw your own conclusions. In general, this is a worthy light trailer, given its rich history and long presence on the market.

To buy such a model or not is a personal choice for everyone. Today the assortment of light trailers is so huge that buying becomes a serious problem. If earlier difficulties were caused by a deficit, today the main obstacle is a wide choice.

A trailer for a car significantly expands the capabilities of a vehicle in terms of the volume of cargo transportation. It is convenient to use both for solving everyday problems and for professional purposes. Without protruding beyond the overall dimensions, without changing the design of the chassis, the equipment can be upgraded without special permission from the traffic police - to build up the sides, make a booth. KMZ 8119 trailers are one of the successful models of the domestic manufacturer.

The towing device of JSC Kurganmashzavoda, like any other technical means of this category, consists of a body, a running gear, a device for connecting to a car and light-signaling equipment.

The body structure of the KMZ 8119 light trailer is a rectangular steel frame sheathed with profiled sheet metal.The wheel arches are located inside the body and do not protrude beyond the overall dimensions. On the opposite side from the drawbar, the body has a hinged tailgate, fixed to the base by means of awnings. It is fixed in the closed position with special latches.

The running gear consists of wheels and a suspension taken from the ZAZ 968m model. With independent suspension, the trailer is able to provide high stability when moving the trailer, and is also less prone to swinging.

Structurally, this drawbar has a folding design. It has a retainer for the ball end of the towbar, plus a chain link with carabiners. The drawbar in the folded state allows the trailer to be stored by placing it vertically upwards.

The work light is represented by side lights with integrated stop lights at the rear, side lights at the front of the trailer. There is also wiring, a standard connector for connecting KMZ 8119 to the electrical part of the car in the line of the relay for turning on its turns. Passive reflective devices are the rear red marker reflectors and warning orange ones on the sides.

The characteristics of KMZ 8119 are as follows:

DShV of the body in meters - 1.85x1.60x0.30;
Carrying capacity - 0.5 tons;
Dumping platform.

good day
From a technical point of view, the re-equipment is considered permissible.
The only remark: how do you plan to be with the total weight, if after the conversion the total weight is less than 750 kg, then there are no problems. If more than 750 kg, then the trailer must be equipped with brakes.
Registration procedure:
1. Take the "application for changes in the design of the vehicle" in the traffic police at the place of registration of your vehicle.
2. Send us copies of documents:
1) Statement from the traffic police from both sides with a resolution.
2) Vehicle passport (PTS) on both sides,
3) a detailed description of the work + drawings or photos, if the re-equipment has already been carried out
4) If you have a technical education, then + copies of these documents
4) Postal address of dispatch
5) Contact information
All documents are provided as copies. Either by email (CONTACTS) or fax.
3. Make the conversion.
4. The following documents will need to be submitted to the traffic police:
1) Application for changes in the design of the vehicle,
2) Conclusion on the possibility of re-equipping the vehicle (get it from us),
3) Declaration on the volume and quality of the work performed.
5.In the traffic police, you provide the trailer for instrumental control and draw up a diagnostic card. In the PTS they make a note about the changes made and give you a new certificate of registration of the vehicle.

As for the self-made chassis - at the moment in Russia there is a legal vacuum in this area, it is very problematic to register a self-made vehicle. Along the way, the conversion is much easier.

Tell me if it is possible to re-equip the MMZ 81021 trailer for the construction of a caravan trailer with a total curb weight of up to 750 kg. to the Niva car?
I plan to do the following:
1. Extend the wheelbase or install a rubber suspension (most likely an extension).
2. Extend the wheelbase by 1500 mm.
3. Strengthen the frame (since I know from experience that this trailer is very flimsy)
4. Remove the trailer body and install the metal floor frame.
5. Install the “living” module directly onto the frame.

Are similar alterations possible with this trailer?
How much will its registration cost to receive a TCP?
How much can the trailer frame be extended and lengthened for a similar vehicle? (I plan to carry out welded work in a car service)

Passenger car trailers often break down as they are subjected to very heavy loads. Most often these are shock and vibration loads, as well as failure to comply with all operating rules. The most common problem that occurs when using the devices is axial deformation and disruption of the suspension geometry. In this case, you need to replace the axes or restore the geometry. The work to be done in such a case is very great. This is cutting of a fresh thread, straightening of the CAF, metal surfacing and much more.

It happens that malfunctions occur due to a breakdown in electrical equipment. Then they may fail:

headlights;
stop signals;
lanterns;
parking lights;
license plate lighting lamps.

In case of malfunctions of one of the listed dimensions, the probability of an accident increases significantly. Therefore, if any malfunction of the electrical part of the equipment is found, it is necessary to contact a car repair shop.

Nowadays, there are many types of specialized accessories for passenger cars: trailers for ATVs, jet skis, boats and boats, trailers, vans, and so on, each of which needs an individual approach, different equipment and a variety of spare parts to repair. The further work of the carrier depends on these components.

The sides of the device are subjected to very heavy loads. Almost all car dealerships have such a service as onboard installation. They can be plastic, galvanized or some other types. Plastic ones are quite cheap, but their performance is very low, due to the fragility of the main material.

The braking system can also fail. This can cause serious accidents, therefore, if you notice any malfunctions, you should not delay with the repair. Most often, it is enough to replace a spare part. This can be a brake chamber or a tap, a pad, a lining, and so on. If you decide to buy a trailer, remember that with systematic operation, devices with brakes must undergo repair maintenance at least once every six months.

For some drivers, trailers are an indispensable part of the car, so their design must be taken care of properly. Airbrushing applied to the trailer gives it individuality and makes it very interesting. It can be any drawing you like, just a pattern or an abstraction.

It is possible to repress the torsion axles of the carriers, which will increase their reliability and service life. Additional axles can be installed on the structure to improve the lifting capacity. It is also possible to improve the braking system of the standard axle. Installing more lighting fixtures will only improve the situation. A lot of light on the road at night is never superfluous. These can be side lights and taillights.

It would seem that trailers for cars should not bring any additional worries. But this is not at all the case. They require constant care, prevention, and sometimes repair. Prevention is not expensive at all, but the results are worth it.

Hello, but my suspension arm has burst, which one will not work?

4610221990 also as an option to make your own from a profile pipe. There is information on the Internet.

4610221990 levers for such a trailer have seen new ones on sale on Avito. I don’t know what will fit.

Wondering if a nine-point stand will work?

Dasha Panda will not work without revision.

Hello, has the capacity on the trailer increased after the revision? and how he began to behave on the road,

Thank you, I want to try to do the same.

+ nik bond Hello. Has increased by about 200 kg. On the way it is going well, it has become a little harder.

Transportation of large loads is a fairly frequent necessity in the life of many motorists.As practice shows, the trunk of a car is often not very suitable. The ideal solution in this case would be to use a car trailer. It should be noted that the caravan is quite relevant not only for household needs, but is also actively used by car travelers.

The first thing a person needs to know who decides to make a car trailer on their own is that certain requirements are imposed on it, like any vehicle. In this case, all the requirements are detailed in GOST 37.001.220-80, which is called "Trailers for passenger cars". In order not to load motorists with reading the original source, it is worth making a selection of relevant information specifically on the issue under discussion.

So, a car trailer must meet the following requirements:

After the entire set of materials and tools is assembled, you can proceed directly to the assembly of the structure.

The instruction will allow you to do everything quickly and efficiently.

If factory trailers for cars do not suit you with something and you decide to make a two-axle trailer for a car with your own hands, then this article is for you.

If you want the State Traffic Inspectorate to allow you to operate your homemade trailer, you need to do it yourself in accordance with the requirements of GOST 37.001. 220-80 "Trailers for passenger cars". For those who do not want to read the original source, we will briefly outline the main restrictions imposed by this document on trailers for passenger cars.

If you decide to make a trailer for a car with your own hands, you will need the following parts and materials.

Traction hitch - 1 pc.
Rear hub axle from a front-wheel drive vehicle - 2 pcs.
Rear hub from the same car as the axle - 2 pcs.
Springs from any machine - 2 pcs.
Spring rear end earring –2 pcs.
Padded stepladders - 2 sets.
Shock absorbers - 2 pcs.
Steel pipe with a section of 30 by 60 mm (2 sections of 190 cm - spars; 2 of 122 cm - beams of the drawbar).
Steel pipe 25 by 25 mm (4 sections of 190 cm each - the bottom and top of the strapping of the side boards; 8 sections of 40 cm each - the racks of the side boards; 4 sections of 119 cm each - the bottom and top of the front and rear boards; 7 sections of 114 cm - cross members).
2 pieces of U-shaped channel # 5 for the manufacture of the bridge beam.
Hinge hinge - 4 pcs.
Side fixing device - 4 pcs.
Rear lights - 2 pcs.
Stranded insulated wires.
Plywood 10 mm thick - 1 sheet (size 1.9 x 1.14 m).
Sheet steel 0.8 mm thick.
Chain or rope Ø 3 mm - 2 pieces of 20 cm.

From the tool you need a welding machine, a grinder and an electric drill.

Fold the sections of the channel so that you get a rectangular pipe, and tighten them with clamps. Boil the joints. Weld the hub axles to the ends. Attach the resulting bridge beam to the springs using ladders.

Spread out the side members, traverses and cross members on a level surface.
Cook them to size.
Turn the structure over and weld the brackets for attaching the front ends of the springs to the side members. This must be done so that from the middle of the beam of the installed bridge to the rear edges of the side members is about 950 mm.
Weld the drawbar and attach the tow bar to it.
Screw the front ends of the springs to the brackets, and the rear ends through the earrings to the side members.
Install the hubs on the axles, and the wheels on them.
Place the trailer on wheels.
Fix the towbar on the ball of the car's towbar.
Roll up the trailer to the drawbar.
Fold the drawbar arms over the side members. Secure the alignment with clamps.
Remove the towbar from the hook, roll the trailer away from the machine and weld the connection of the drawbar to the side members.

Sheathe the sides with sheet metal. Make the floor by attaching the plywood to the crossbars with countersunk self-tapping screws. Cut the wings out of sheet metal and attach them to the sides with brackets. Prime and paint the structure. Attach the lanterns and route the wiring.Use a chain or cable to make the tow hitch insurance. Only after that you can proceed to registration.

Do you want a dual axle? Weld 2 bridge beams, buy 4 short springs and set everything so that the distance between the axles is no more than a meter.

A homemade trailer, which can be used without fear, must be registered with the MREO GBDD. To register, you must have:

Conclusion of a technical examination on the compliance of a self-made vehicle with the requirements of GOST001. 220-80. Where it is possible to make such an examination, you need to clarify in the MREO. Since the conclusion issued by a laboratory not accredited by the State Traffic Safety Inspectorate may be invalidated.
Receipts confirming the purchase of parts and materials used for the manufacture of the vehicle.
A certificate for the hitch hinge (that's why we advise you to buy it, and not do it yourself).
A copy of your passport.
A copy of the traction vehicle registration certificate.
Application addressed to the head of MREO with a request to register a homemade trailer.
Receipt for payment of state duty.
4 photos of homemade products taken from different sides (10 by 15 cm).

If you submit all these documents, then you will be admitted to the technical inspection. A positive technical inspection result will be the basis for registering a self-made vehicle.

Trailers on the road are subject to frequent shock and vibration loads, so they often break down. The high requirements for the driver of a vehicle with a trailer are mostly justified. And the trailer itself must have strong components, a reliable braking system and be stable on the road.

The most common trailer breakdowns are axle deformation and suspension geometry disturbances. To eliminate these breakdowns, you need to restore the geometry and change the axis. To do this, a lot of work needs to be done, namely, cutting a new thread, straightening the CAF, weld metal and much more.

Wheel play. This can be due to either loosening of the bolts or nuts that secure the bearing, or the destruction of the bearing itself.
Hitch ball play. The reason is either the wear of the parts of the coupling device and their deformation, or dirt inside the device.
Brake system malfunction. The brake pads may be worn out and need to be replaced.
Excessive brake drum temperature and braking. Dirt may get on the brake cables, or the brake rod may jam.

Faults in electrical wiring:

Lights, brake lights, side lights are off. Broken wire or burned out light bulbs.
Blown fuse in the vehicle. Short circuit in the trailer wiring.

If you are not able to eliminate a malfunction in the electrical equipment yourself, contact a specialist in a car workshop for help.

The most common type of trailer breakdown is axle, half-axle or wheel bearing breakage. Such malfunctions arise due to the influence of dynamic and shock loads that arise during the breakdown of the suspension, due to the inconsistency of the energy intensity of its elastic elements with real load conditions.

Avoiding such breakdowns will allow the presence of a suspension travel reserve with the use of shock absorbers to damp vibrations. In turn, two- and three-axle trailers simply cannot do without compensating devices (anti-roll bars and jet rods).

The presence of a high-quality lock will extend the service life of the trailer and the car. The lock should have a strong body with thick walls, a strong coverage of the towbar ball with breadcrumbs. Its main task is to exclude the disconnection of the trailer, for example, during a sharp turn. The ball of the towbar must be lubricated for the hinges. This grease protects the clutch mechanism from wear.

When choosing a hitch, special attention should be paid to the strength of its frame. Usually it is performed welded.Some manufacturers strive to obtain maximum frame strength at minimal cost, while increasing the cross-section of beams, drawbars, side members. With a decrease in the total mass of the trailer, the loading height increases, the hitch and the locking device are loaded, and the stability of the trailer itself deteriorates. Some unscrupulous manufacturers use bent thin profiles at all, which is not very reliable.

Due to its low cost, the most widespread is the cable drive of brakes. Its disadvantage is that it stretches and wedges in the shells. The cable brake is recommended to be used only for parking, therefore, it should not be used in the service braking systems of the trailer.

Trailers weighing up to 3.5 t are equipped with hydraulic brakes. With a hitch weighing more than 3.5 tons, a non-inertia braking system is used. If you find one of the above malfunctions, you should fix it as soon as possible to avoid an accident.

Sometimes the capacity of the trunk of a car is not roomy enough for many motorists, especially if the transportation of bulky goods is required. A trailer is best suited for this task.

Trailers are of two types, produced by a specialized factory or self-made:

Factory trailers do not require additional permits for their registration and registration. But at the same time, factory trailers do not always suit motorists with their technical characteristics, and if they do, then their price is not measuredly high. And the quality of the trailers themselves is not at a high level, which requires additional investments after purchase to eliminate factory defects.
A homemade trailer is a structure that a motorist assembles according to his drawing from a material that is outdated in quality, while adhering to GOST standards for its assembly. As for the registration aspects of such a product, they are much more expensive than when registering a factory one, since additional permits are needed to operate a homemade trailer.

From an economic point of view, the cost of a homemade trailer, taking into account all registration costs, is significantly lower than buying a new one.

It is also worth considering that a homemade trailer will be of much better quality than a factory one, if only because the entire manufacturing process will be controlled by the motorist himself.

The first thing you need to make a trailer with your own hands is a drawing.

It is also worth noting that the drawing must comply with GOST standards 37.001.220-80.

This standard indicates all the requirements that are necessary in order to obtain a permit for the operation of a trailer and its further registration at the Interdistrict Registration and Examination Department.

In addition to the blueprint, you will need the following materials to make a homemade trailer.

Also, to make a homemade trailer, you will need the following tools:

Welding machine - preferably a semiautomatic device, but you can also use a conventional arc.
Grinder and wheels for cutting metal.
Drill and drill for metal.
Roulette and hammer.
Screwdriver, wire cutters.

After all the necessary tools and material have been purchased, you can proceed directly to the assembly process itself without deviating from the dimensions indicated in the drawing.

Cutting materials for assembling the trailer is carried out according to the dimensions indicated in the drawing.

Assembling a homemade trailer consists of the following steps:

The wiring of the trailer is laid according to the same principle as in the car, the negative wire is attached to its frame (ground), and the positive wire to the contact of the lighting device.

For registration in MREO a technical data sheet and a product number are required.

Of course, a homemade trailer cannot have either the first or the second.

Therefore, in order to register a homemade trailer it is necessary to make documents for it that confirm that this product complies with GOST standards and safe for use on public roads.

Also, do not forget that you will have to contact the office that deals with the filling of numbers on vehicles and only after the number on the frame of the trailer is filled with the number can you begin the process of registering it.

In order to register a homemade trailer, the following documents will be required:

Statement to the head of MREO for registration of the trailer.
Identification.
Technical passport vehicle.
Laboratory certificate allowing the use of a trailer on public roads (for homemade trailers).
Documents confirming the ownership of the registered trailer (power of attorney certificate account).
Receipts confirming payment of state duty and for the services of MREO.
Check-in trailer or technical inspection report.
CTP insurance policy.

The trailer registration process consists of the following steps:

Writing a statement... Arriving at MREO, you need to write a statement addressed to the head of the registration of the trailer. Typically, a spelling sample is issued along with the application form.
Payment for services and state fees. After writing the application, the person is given a checking account, where it is necessary to pay the state duty, MPEO services and for materials (registration certificate, numbers).
Delivery of documents. After the payment of the state duty and services has been made, the receipts, together with the necessary documents and an application, are submitted to the registration window. After that, you can go to the site and wait for an inspector who will inspect the trailer (if there is no inspection report).

Strange as it may seem, but it is also necessary to purchase an insurance policy for a trailer. But, according to the law on OSAGO parts 2 and 3, not everyone is obliged to draw up an insurance policy. Private owners of trailers for cars, who used them for personal purposes, have the right not to purchase an insurance policy.

As for the list of trailers, for which the purchase of an insurance policy is mandatory, the following vehicles belong to it:

Trailers for cars of legal entities.
Trailers for trucks and tractors.
Trailers for buses.
Trailers for motorcycles and scooters.

In order to issue an OSAGO insurance policy, the trailer must undergo a technical inspection without fail. Otherwise, the policy will be refused.
