Hub replacement, Kurgan trailers. Interchangeability of hubs, design characteristics of wheel hubs

Welcome everyone!

And again about the technical features of Kurgan trailers.

The products are famous for their reliability. The peculiarity is that the most critical components of the trailer, for example, wheel hubs, are manufactured at our own production base. Many note that the design of the hubs is quite successful. This can be judged by the fact that questions are increasingly being asked about the possibility of installing hubs on trailers of other brands.

This article is about the design characteristics of wheel hubs. Specialist developers have covered this issue in sufficient detail on their website in the forum section.

The hub and axle are manufactured directly at the enterprise. The double-row ball bearing was borrowed from the VAZ 2108. Its marking is 6-256706E1S17. It is sealed and does not require lubrication or adjustment during operation. The holes for mounting disks coincide with VAZ ones - 4 pieces with a diameter of 98 mm. The hub axle is secured to the wheel beam flange with four spring washers. The beam flange has 2 additional holes, which allows you to increase the ground clearance of the trailer if you move the axles to the lower position. When equipping a trailer with wheels from a Niva or UAZ, hubs for bearing 127509 A, a UAZ hub seal, and wheel studs 2121 are used.

PS If you want to replace the hubs on passenger trailers of other brands (NOT from the Kurgan Trailers production plant), then you may need to manually modify the beam, since the holes for attaching the axle to the flange may not match.

Replacing the MZSA trailer wheel bearing

Sooner or later, any owner of an MZSA trailer is faced with the need to replace the wheel bearing. As a rule, ALKO bearings installed from the factory are designed for 100 thousand mileage. If the trailer has been overloaded or has wheels larger than those recommended by the manufacturer, the need for replacement may occur much sooner. Bearings on trailers intended for transporting water equipment have a shorter service life - when regularly immersed in water, moisture enters the hub structure, which has a destructive effect on the bearing mechanism.

Wheel bearing tightening torques

When tightening a new car part, you must follow a number of rules. They will allow you to significantly increase the service life of this element.

Front hub tightening

In order to tighten the front hub, you need to perform the following steps. To begin, use a jack to hang the hub, removing the protective cap. This will allow access to the tightening nut, after which it is necessary to remove the lock nut. After this, rotate the hub and begin tightening the nut. Once the hub has rotated, loosen the nut by 6th of a turn and tighten the locknut. The recommended tightening torque is in the range of 137-157 nm.

Replacing the MZSA trailer wheel bearing

It is quite simple to identify the need to replace a wheel bearing - the presence of play and a characteristic crunch when turning a jacked wheel “hint” at the need for repair work.

Required tools:

• Jack
• Balloon wrench
• Head 32 with knob
• Lubricated bearing set
• Screwdriver or chisel
• Rags

Sequencing

1. Jack up the “problem” wheel and remove it.
2. Using a screwdriver or chisel, remove the protective cap of the hub.
3. We bend the pin and, using pliers, pull it out of its seat. Now the lock washer can be removed without any extra effort.
4. Unscrew the nut and remove the entire structure from the axle.
5. We replace wheel bearings. Depending on the modification of the hub, there may be two bearings (internal and external) or one.
6. We fill the bearings and free cavities with grease.
7. Install the hub in reverse order.
8. Do not under any circumstances tighten the nut to 32. It is important that the wheel rotates without unnecessary load.

If you have the necessary tools and minimal skills, replacing wheel bearings on an MZSA trailer will take a minimum of time. Otherwise, it is better to contact specialists.

How to change a wheel bearing

First, you need to make sure that this element of the car hub is really out of order. In addition to unpleasant sounds, there are other signs of malfunction. Firstly, this is excessive heating of the wheel rim. Secondly, the appearance of noticeable play, which may also serve as a basis for replacing the wheel bearing. You can determine these signs yourself.

How to remove a wheel bearing

Let's start with the fact that it is difficult to carry out such a procedure independently even for an experienced driver. Especially if the breakdown occurred during a trip, repairs in the field are simply undesirable. It’s better to drive slowly to the nearest car service center, where they will explain to you how to remove the front hub and help you do it. A big problem will also be the option when your car has a non-separable structure. In this case, you will have to change the bearing along with the hub, and this can only be done under stationary conditions. This also applies to shooting the rear bearing; this process is not much different from working on the front version.

How to change the front wheel bearing

This process is quite complex, is carried out in several stages and requires the use of a certain set of tools:

• Lifting device for the machine;
• Bearing puller;
• Remover of retaining rings and bits;
• A regular hammer may also come in handy.

Service station specialists use a professional set of tools, which has a number of additional accessories. If you don’t know how to change the front hub, don’t hesitate to entrust this task to professionals. Despite the differences in the design of this part of the car, there is a general sequence for performing such actions.

It is necessary to remove the wheel to gain access to the hub. To do this, you need to use a lift to raise the front of the car. For cargo transport in such conditions, special equipment will be required. It is often simply not available in small car services. Then the caliper mounted on the brake mechanism and the brake disc itself are removed.

Repair and maintenance maintenance of MZSA passenger trailers

Like any mechanism, a trailer requires systematic maintenance and repair. As part of a road train, the trailer is a participant in road traffic. And in order to make this movement safe, the AUTOHART Company recommends that all trailer owners regularly carry out maintenance. Sometimes on public roads you can come across trailers that are really scary to drive on the same road. Unfortunately, along with the abolition of technical inspections on trailers, trailers began to appear on Russian roads that, in better years, probably would have immediately ended up under pressure and scrap metal. But all this, as they say, is for the time being.

If you don’t want to get into road accident reports, then we recommend that you service your trailer regularly, and it will serve you for a long time. It is better to entrust repairs to specialists.

The AUTOHART company has been working in this market for 20 years and we know almost everything about trailers

Maintenance, as recommended by the manufacturer of spare parts for MZSA AL-Ko Kober trailers, must be performed once every 15,000 km. Perform maintenance after running in a new trailer and then every 10,000 km or 12 months, whichever comes first.

The AUTOHART company offers to provide this service:

For trailers without brakes - cost from 1,000 rubles.

For trailers with brakes - cost from 2,000 rubles.

List of work carried out:

Self-assembly of the structure

Let's assume that you already have a trailer frame and have chosen your trailer wheels.

Now you need to figure out how it all comes together and turns into a full-fledged axle as a structural element of your car trailer. Let's look at a few key steps.

• To begin with, the beam itself is selected. It doesn't matter whether it has a round or square cross-section. The main thing is that you take the appropriate dimensions and use high quality metal. Otherwise, the suspension will not last long;
• Next, we take the hub axle, on which the hub itself will be installed, and connect it to the pipe. How to connect these two elements? It will be ideal if the hub axle fits at least a few millimeters with its protrusion inside the pipe. Here, a round section has a better chance than a square one. Then it’s all welded or bolted together. Learn from Kurgan trailers if you want to make a collapsible model. If not, just weld the elements together efficiently. This is done on both sides;

• Now you have a full-fledged axle ready, to which a spring or torsion bar will then be mounted;
• According to current rules, the trailer axle is mounted to a length corresponding to 40% of the total length of the trailer on the rear side;
• Make the replacements accurately, mark the location for your axle;
• It is better to perform installation from above, that is, the trailer will have to be turned over and placed on a flat surface. Make sure the spindles hang freely and do not interfere with your work;
• Clean the area of ​​the frame of the future trailer where you will mount your axle. Measure the distance between the bushings and divide into two equal parts. Don't forget to mark everything with a marker on the axis;

What kind of puller is used to remove bearings?

In order to quickly and correctly remove the bearing, a special hub puller is used. There are several varieties of such a device, among which the most common are homemade and universal. They may have various design features:

• With conical type clamp;
• With sliding grips;
• With rotating grips;
• With a separator.

Homemade puller

Devices of this type have a number of obvious advantages. Among them, the main ones are cheapness and simplicity of design. If you have the necessary knowledge, you can easily make such a puller yourself. To do this, you only need a few bolts, a couple of metal plates and bars made of almost any metal. As a result, you will have a simple but effective device at your disposal.

With its help, you can easily remove a failed bearing from the hub. This part is removed using clamping lips. They can be freely adjusted, so that worn-out machine parts of different diameters can be replaced. It is no coincidence that such a device is used not only by car enthusiasts, but also by workers of small car service centers.

Universal puller

Most often, service stations have just such devices at their disposal for removing a bad bearing.
However, it must be taken into account that the universal wheel bearing puller is capable of performing other tasks. It can be used to remove pulleys, gears and other parts. It is for this reason that it has become most widespread. The main element of a universal puller is a power bolt, thanks to which forces are transmitted to the clamping elements that grip the part being dismantled. These devices differ in the design features of the grips and are divided into:

• External, with clamping elements directed inward;
• Internal – with external grips;
• Universal – with the ability to use the functions of both external and internal grips.

Body repair

• diagnostics and replacement of trailer locking devices
• general inspection of the integrity and geometry of the frame, checking the tightening torque of the bolts
• adjustment and replacement of levers and frog locks for tilting the platform and opening the sides
• restoration of trailer zinc coating
• replacement of sides, bosses, plywood, load securing loops and other body parts
• extension of sides
• Replacement of carpeting on trailers for transporting water equipment

Do-it-yourself tow hitch for a walk-behind tractor

Auto mechanic, specializes in agricultural equipment

A walk-behind tractor is a pretty useful thing on the farm. It becomes an even greater help if it is equipped with a trailer in which you can transport various things, tools and materials. Some models of walk-behind tractors on the market do not meet the buyer's requirements. By purchasing such a powerful assistant, their owners plan in advance to begin manufacturing an additional towbar for the walk-behind tractor themselves.

Such attachments significantly save costs rather than buying a finished product. So, how to make a trailer for a walk-behind tractor with your own hands?

You can make a trailer yourself

Introduction

Naturally, every car is different, and there are quite roomy cars, but today we are talking about middle-class cars, which, alas, cannot boast of much spaciousness even for passengers, let alone the trunk. Moreover, there are an overwhelming number of such cars on the roads of Eastern Europe.

No one has canceled the cargo taxi, which can accommodate a lot of things, but the prices for such transportation are not small, and if you need to transport cargo over a long distance, it can hit your pocket hard. But what to do if you need to transport cargo repeatedly, for example, to the country or for work?

A homemade trailer is the best solution to the problem of lack of capacity. One thing is clear here, that such a vehicle will make each driver more independent, and will allow transporting a variety of cargo much faster and more profitably.
