Pressing out the clip
The holder is pressed out after removing the worm gear. To do everything right, first of all, all the necessary tools are prepared. It should also be noted that the keys will be of different sizes. The screws on the MTZ-82 front axle can be screwed with or without rings. In this case, the seals are pryed off with a sharp object.
The spacers are only located at the bottom of the worm gear. In order to reach the holder, the stop is removed from the gearbox. In this case, the cuff must be held very carefully. If leaks are detected, the part is replaced. After removing the stop, the clamping nut of the bridge is unscrewed. Next, all that remains is to disconnect the driven gear. There is no need to touch the disks on the bridge to press out the holder.
Device
The frame of the tractor is a semi-frame structure with supporting housings for transmission elements. The machine layout is classic, with different-sized pneumatic wheels on the rear drive axle and a front guide.
1,2 — oil and water cooling radiators; 3 — power steering; 4 — water pump; 5 — oil pump; 6 - electric generator; 7 — oil filter; 8 — casing of clutch units and speed reduction gearbox; 9 — PTO unit; 10 — attachment with a pneumatic system valve; 11— hydraulic cylinder of the attachment; 12 — air filter housing; 13 - diesel engine.
Operator's cabin
Rigid construction, sealed, with tip-over protection. Mounted on 4 rubber vibration mounts. Ventilation is natural. Machine control The steering is equipped with a power amplifier, powered by an individual hydraulic pump. Braking of the machine and trailer is provided by a pneumatic system. Dry disc brakes are mounted on the side gears.
Vertical shaft operation
The vertical shaft of the front axle is responsible for the gear rotation. The shaft is attached directly to the gearbox. Experts say that the model is capable of maintaining high speeds. The flange of the modification is used with an adjusting adapter. In the lower part, the thickness of the shaft is 4.5 cm. The glass is selected with a small diameter. At the top of the modification there is an overlay. In this case, there is no seal under the shaft.
In order to twist the shaft yourself, use a screw wrench. The device tube is unscrewed manually. To disconnect the shaft, the gearbox does not need to be removed. When checking a part, the front axle is first inspected. If cracks are found on the body, the part needs to be cleaned. In this case, the running gears are lubricated with machine oil. It is also worth noting that the flange must be thoroughly cleaned. The thrust rollers in the mechanism require periodic inspection.
Removing the wheel from the gearbox
The wheel can be removed from the gearbox quite quickly. However, it is problematic to cope with this task on your own. When repairing the MTZ-82 front axle, it is recommended to inspect the gearbox housing. Next, remove the cover, which is fixed on two stops. The center screw is the last to be removed.
It should also be noted that it is important to thoroughly clean the lining under the lid. Gasoline is suitable for this. The rector wheel is located behind the regulator. To get to it, two screws are removed. The longitudinal stops of the bridge do not need to be touched. The wheels in the device are held on by one nut, which is tightened with a wrench.
Reviews about the car
Most owners of "Belarus 80" and machine operators who service it note:
- The machine is universal in use, easy to operate and repair, and the demand for spare parts and components is fully satisfied.
- The power plant is reliable, starting is not difficult, does not require high quality fuel, and lasts until major overhaul without serious breakdowns.
- Multifunctionality is determined by more than 200 types of trailed and mounted mechanisms.
Among the shortcomings, experts highlight:
- Insufficient level of comfort and small cabin size of the base model. Ventilation is natural through windows, there is no heater.
- Low reliability parameters of hydraulic steering systems and canopy assembly. Oil leaks, hydraulic pump failures.
Minsk tractors "Belarus 80" with a traction class of 1.4 are used as multifunctional units in agriculture, construction, and industry. Simple and reliable machines do not require high qualifications from the tractor driver and repair personnel. In modern models, the power supply of the unit has increased significantly and the comfort of the control cabin has been increased. The prices of the products are reasonable and correspond to the characteristics and quality of the tractors.

The MTZ-80 tractor is the basic model of Belarus tractors, which has been produced since 1974 at the Minsk Tractor Plant (MTZ). Due to high technical, economic and operational indicators, agricultural machinery is widespread both among small farmers and among large agricultural, industrial and road repair enterprises.
The areas of application of a wheeled tractor are extensive. It is used for row crop farming, which includes the cultivation and harvesting of corn, potatoes, sugar beets, sunflowers and other crops. The unit easily and quickly prepares any type of soil for sowing, performs cultivation, harrowing, plowing, and hilling. It is often used for transport, loading and unloading, road construction and other operations.
In this review, we will consider in more detail the description of the parameters and characteristics of the 80 wheeled tractor.
How to remove the gearbox cover?
The gearbox cover is removed using a 8mm wrench. Experts say that the linings in the device often dry out. In this case, the clamps are very tightly fixed. In this case, unscrewing the lid can be problematic. In this situation, it is recommended to tap the device immediately. A small hammer is used for this. It is necessary to knock on the edges of the lid. Next, the screws are unscrewed alternately on both sides. During this, it is important not to damage the lining that is located in the gearbox.
Bridge cuff
The cuff holds the worm gear. On MTZ-82 (front drive axle) it is mounted with two stops. Sometimes the device needs to be replaced. For this purpose, the rollers are removed and the driven gear is inspected. After adjusting the part, you need to start inspecting the glasses. You must also remember that seals need to be replaced periodically. The bridge cover must be tightened thoroughly.
Worm mechanism
The worm gear on the MTZ-82 front axle is installed with a connecting rod. In this case, three gears are used, which are locked on a stop. The regulator is installed on the MTZ-82 front axle with a friction mechanism. At the front of the worm gear is a small coin. In this case there are no linings. There is a large nut at the back of the part. There is a ring underneath it. The cover of the device is fixed with a clamp.
The breather is located in the central part of the worm gear. When this device breaks down, the fastener is first unscrewed. A wrench is used to remove the nut. In this case, a cuff is not needed. The regulator can be easily disconnected by hand. When the ring is closed, the lower stop is knocked out. This can be done using a regular hammer. When the seal wears out, the stand is unscrewed. The filling mechanism also needs to be checked. If the body is damaged, the cup is checked. If cracks are visible on the kingpin, they must be coated with machine oil. Experts say that the cuff needs to be changed every two years. At the same time, pads are very cheap.
How is the clip pressed?
To press the clip, wrenches are used, and an additional hammer is required. Before starting work, the condition of the worm gear, which is installed on the MTZ-82 front axle, is checked. Its cover must fit tightly to the body of the modification. In this case, the regulator does not need to be touched. After removing the cover, the stop is disconnected. If the cage is tightly clamped, the screw turns clockwise. In this case, the pads should not be pressed too tightly. If the flange begins to sag during operation, then you will have to check the roller mechanism. In some cases, the problem is with the drives. In such a situation, the protective sleeve is unscrewed. Next, it remains to check the condition of the thrust ring and its clamp. At the end of the work, everything is lubricated with machine oil.
