Malfunctions and repair gaps

The main list of malfunctions leading to stopping the operation of the tractor and subsequent disassembly and repair of mechanisms at intervals:

1. Sometimes clutch linings slip when the main oil seal on the input shaft wears out. Oil flows between the flywheel and the driven movable disk.
2. There is no braking of the gearbox input shaft. Shifting gears is difficult or makes a grinding noise. Adjust or replace the clutch brake.
3. Spontaneous shutdown of the independent PTO rotation speed
4. Transmission oil leaks from the housing at intervals.

The overall operation of the unit depends on the condition of the support bearings of the drive power and driven PTO shafts. Due to the increase in play in the supports, the gaps in the engagement of gear blocks of the gearbox and splined joints increase, which leads to increased wear of parts, the appearance of a hum, beating during operation, and spontaneous knocking out of the PTO speed position.

To replace support bearings, shafts and gears in between, complete dismantling of the unit is required, followed by disassembly and replacement of worn parts.

Replacing oil seals in between

To replace the oil seals on the shaft supports in the front partition of the housing, the gaps on the power shaft, the driven PTO shaft and the hydraulic system pump drive axis, the following steps must be performed:

1. We remove the hood.
2. Disconnect the transfer case driveshaft.
3. Unscrew the nuts securing the unit with the motor.
4. Using the front wheels, we roll the engine away from the gap.
5. Remove the lifting mechanism with the bracket.
6. We change the seals.
7. We collect cuttings.
8. We roll up the tractor.
9. We fasten the gap.
10. Install the hood.

In the upper front support of the pump drive axis, the rubber sealing ring is replaced. The fixing bolt is unscrewed from the axle. Then remove the bushing and replace the o-ring. If the bushing and seat are broken, grind a new one of a larger size.

In the middle front support between the power shaft and the PTO drive shaft, the oil seal is replaced, clamped by a sleeve and a bushing.

The lower support is sealed with an oil seal and closed with a cup-shaped cover with four bolts.

Repair practitioners pay attention! When installing the gaps with the gearbox, before tightening the fastening bolts, you need to make sure that the splined connections of the lower shafts of the PTO gaps and gearbox do not rest against the spline. This will not create a longitudinal force on the shaft, which, when tightening the units, will squeeze out the oil seal and the shaft support cover, and will not lead to oil leakage.

The tightness of the seals between the dry clutch compartment and the lubricated part of the gap ensures the tightness of the general lubrication system of the tractor transmission and isolates the clutch friction discs from oil, which causes slipping.

Repair of the drive and speed change gear of the independent PTO

Malfunctions of the unit include knocking out the on position of the PTO rotation speed. One of the reasons is a malfunction of the spring-ball retainer of the fork on the shift axis installed in the lower housing cover.

• Remove the cover with the switching drive
• Disconnect the shift fork and axle, gaining access to the spring-ball retainer
• Inspect or replace parts of the retainer
• Reassemble the axle and fork in reverse order

Clutch brake repair

The working mechanism of the brake consists of movable and fixed disks and a rod system connected to the pedal. The surface of the discs is protected by friction linings, which, when compressed, stop the clutch and the input shaft of the unit.

The main malfunctions of the device arise in the event of incorrect adjustment of the levers or premature wear of the ring linings. The recommended thickness of the friction plates is 5 mm, the amount of wear is no more than 3 mm. Work to restore the brake is carried out simultaneously with changing the oil seal.

To get to the mechanism disks, in addition to the work listed above, you need to remove the lift bracket and the middle top cover on the housing. The factory-made linings are connected to the surface of the disc using special glue. The repair procedure in this case consists of replacing the fixed and mobile disks with new assembled products.

Correction of the rod length is carried out using a threaded coupling located on the rod of the device. Just below there is a working spring, the size of which must also be adjusted (≤ 35 mm).

The technical condition of the gap mechanisms affects the operation of the entire tractor transmission. In the event of problems during the operation of the tractor gearbox and difficulty engaging gears, the reasons should first be sought in the mechanisms of the described unit.

Repair of tractor clutch MTZ-80, MTZ-82

Slipping of the clutch or incomplete disengagement of gears leads to increased wear and breakdown of clutch parts, gearbox parts, rear axle and front drive axle of the MTZ-80, MTZ-82 tractor. The technical condition of the clutch can be determined by a number of signs that characterize a particular malfunction.

The appearance of abnormal noise and knocking, difficult gear shifting, clutch slipping, especially with increasing traction force, which cannot be eliminated by adjusting the clutch drive, indicate wear or destruction of clutch parts.

Increased noise or whistling when pressing the clutch pedal indicates destruction of the release thrust bearing. If the clutch drive of the MTZ-80, MTZ-82 tractors is incorrectly adjusted, which is characterized by the lack of clearance between the thrust bearing and the pressure levers, the bearing constantly rotates.

Belarusian tractors are usually distinguished by high reliability and profitability with low operating costs and highest productivity. In the vastness of Russian fields, the MTZ-82 tractor performs various agricultural tasks. This tractor is very popular on Russian farms.

production

Delivered to car showroom,

Mainly assembled by Minsk Tractor Plant.
But soon Belarusian tractors are intensively entering into production cooperation, opening assembly flows, developing an equipment service network, and increasing spare parts.
Saransk has an assembly site based on the installation of Belarusian tractors with ready-made components and assemblies supplied from the main assembly flow. Local Russian machines for the assembly of finished parts made in Belarus are somewhat cheaper.

A little history

The MTZ universal tractor series began to be created in the 1970s after a special resolution of the USSR Council of Ministers. The government has decided to introduce a powerful agricultural tractor (up to 80 HP) in the agricultural sector. A modernized version of the MTZ-50 tractor has been developed. Many configurations have been made to the machine's design, and the lining and cabin have also been updated.

The MTZ tractor series began to be created in the 1970s.

A new engine with high power was installed on the tractor. In 1972, the first tests of the MTZ-82 were very successful. Based on the test results, a list of aggregated equipment was compiled; In total, more than 230 devices were created for various types of work. Acceleration of the tractor to 30 km per hour made it possible to use it in transport operations.

The first tractor collapsed at the Minsk plant in 1974. The first reviews of the MTZ 82 were positive. And Belarusian tractors machine productivity began to increase. Almost four decades of technology Minsk plant Cultivated fields on almost all continents of the world. They are especially popular in developing countries in Asia, Africa and Latin America.

Tractor designation

Firstly, the equipment is designed for field work. It is positioned on the market as a functional and all-wheel drive medium tractor. The tractor can sow, harvest, plow winter plows, spring wedges. Often a tractor with attached equipment, with trailers, is used to move goods, for ground and road work.

• mechanical locking of the rear connection
• cross member

General device

Diesel power station. The engine is a 4-stroke, 4-cylinder engine with a power rating of 82 horsepower. Engines are also available on City Tractor. In Minsk engines, the combustion chamber, made in the pistons, is divided in half. There are tractor models on the market with a starter heater. The total engine power is 4.75 liters and the speed reaches 22,000 rpm.

The main brake and parking discs are dry. Brake drive for pneumatic trailers. Locked on the car brakes. Electric current for the tractor is generated by a 700 W generator with a voltage of 14 V. Upon request, the system can be supplied with a voltage of 24 V. The driver's workplace is comfortable, the cabin is isolated from noise, and there is good visibility.

All tractors are equipped with a manual transmission. The 9-speed MTZ 82 is equipped with a gearbox and has 22 gears. a total of 18 front, four rear.

The rear wheels are mounted on rigid and semi-rigid suspension. MTZ-82 tires are also supplied by Belarusian manufacturers. If the farmer is constrained by price, there are always excellent options on the secondary market.

Advantages and disadvantages of the tractor

During operation, the cost of servicing a Minsk tractor is minimal. And this is the main factor that farmers value. The car has high reliability . And on Russian fields, the tractor is not inferior in productivity to its European counterparts. And sometimes it even surpasses them. Over the years, the Minsk tractor has gained a reputation as a "non-destructive vehicle" that cannot be affected by terrain, temperature fluctuations, dust, heat, rain, snow and frost.

The tractor is easily aggregated with a large number of attachments. Easy to use. The developers tried to create a certain level of comfort for the driver in the cabin (as far as this word applies to cars developed in Soviet times). The machine meets modern ergonomic standards.

Disadvantages and common problems

Some farmers point to the insufficient performance of tractors when processing large contours. from 80 hectares and more. Under high load, third and sixth gears are quite weak.

In general, the engine is not insured for fuel quality. But with low-quality diesel fuel, the diesel engine may stall and not start at all. What to do The problem is often solved by adjusting the injectors and replacing diesel fuel.

If black smoke comes out of the exhaust pipe, immediately reduce the load on the engine. If white and blue fumes occur, the fuel system must be repaired and the thermostat adjusted.

Particularly alarming is the “healthy” sign of detonation technology in a diesel engine. Stop work, perform diagnostics, replace worn rings and bushings.

If oil consumption is excessive, worn parts are also replaced and piston rings are replaced.

Production

Rear power take-off shaft MTZ. Part 2. Disassembly.

This video shows how to disassemble the rear power take-off shaft

Adjusting the power take-off shaft

Adjusting the MTZ PTO (power take-off shaft):

1. Place the vehicle on a special viewing platform.
2. Set the axis of the central disk of the main system to its original position.
3. The applied mark should be located on the right side in a vertical position, i.e. o will be on the right.
4. Secure the risk using locking plates and screws.
5. Disconnect the rod.
6. Unscrew the cup screws to release the spring mechanism.
7. Remove the rear drive axle hatch cover to gain access to the tension bolt head.
8. Place the clutch handle in neutral mode and secure it with the M10*60 locking bolt. It screws into the hole on the lever, which should be located on the rear of the drive axle housing. After this, the locking plate is removed; it can be removed by removing the locking handle.
9. Screw the thrust bolt into the outer glass until about (27-31 mm deep).
10. Move the handle to the “On” position.
11. Reinstall the traction mechanism. Then adjust the handle play by setting the required handle swing zone in the middle hole of the control panel slot.
12. Check the speed rotation at the rear PTO shift speed.

After checking, the shaft is installed back on the MTZ-82 tractor.

Nuances of adjustment

Additionally, adjustment of the band brake mechanism may be required in cases where:

• the shaft begins to tow;
• the handle rests against the slot during switching;
• to activate the PTO, a force of more than 16 KGS is required;
• there is unstable fixation in extreme positions;
• The PTO engages unevenly (it either doesn’t work or works).

Procedure for adjusting the band brake mechanism:

1. Set the handle to synchronous mode. Fix the position of the handle.
2. Unscrew the nut and remove the plate from the shank slot.
3. Using an open-end wrench, turn the axle mechanism clockwise until the gap between the gearbox and PTO is selected.
4. Place the plate in its original position and tighten all the nuts into place.
5. Remove the locking bolt from the handle.
6. Perform adjustment.
7. Turn the axle counterclockwise.
8. Reassemble the mechanism in reverse order.

If, after performing work to adjust the brake mechanism, the axle has shifted to the left side of the vehicle body, this means that the power unit has used up its correction reserve.

In this case, you need to turn the eccentric counterclockwise, returning it to its original position. After this, the shaft is adjusted again.

PTO adjustment

When adjusting the power take-off shaft on the MTZ-80(82), the following sequence must be observed:

After the adjustment is completed, it is necessary to return all the parts to their places in the reverse order and tighten the bolts with locknuts.

If the shaft begins to slip or it is unstable, or increased force is required to turn it on, or other similar problems, it is also necessary to adjust the band brake mechanism:

General device

The power plant is diesel. The engine is 4-stroke, 4-cylinder, with a design power of 82 horsepower. Engines are also produced at Minsk Tractor Plant. In Minsk engines, the combustion chamber made in the piston is divided in half. Tractor models with a pre-heater are also available on the market. The total engine volume is 4.75 liters, the speed reaches 22,000 rpm.

The main brakes and parking brakes are on discs, dry. Pneumatic brake drive for trailers. Locks with car brakes. Electric current for the tractor is generated by a 700 W generator set with a voltage of 14 V. A starting system with a voltage of 24 V can be supplied upon request. The driver's workplace is comfortable, the cabin is isolated from noise, and good visibility is provided.

All tractors are equipped with a mechanical transmission. The 9-speed MTZ 82 is equipped with a reduction gearbox and has 22 gears - a total of 18 forward, four rear gears.

The rear wheels are placed on a rigid suspension and mounted on a semi-rigid one. Rubber for MTZ-82 is also supplied by Belarusian manufacturers. If the farmer is put off by the price, there is always a large selection on the secondary market.

Device Features

Looking at the gearbox of the tractor model in question in a section along the longitudinal axis, you will notice the uniaxial placement of the secondary and primary shafts. The reverse shaft with the first gear shaft and the intermediate shaft are parallel to the primary one. The front end of the input shaft is fixed in the gearbox housing cup bearing, while the rear end is attached to the front end of the secondary shaft at the end of the bearing.

The drive gears of 3-5 gears are fixed on the splines of the input shaft. The reduction gearbox is also fixed there due to the driven gear. Driven gears 3-5 of the gear selector are fixed on the splines of the hollow intermediate shaft. The third gear driven gear is engaged with the intermediate gear.

Advantages and disadvantages of the tractor

During operation, the costs of maintaining a Minsk tractor are minimal. And this is the main factor that is valued by farmers. The car has high reliability . And on Russian fields, the tractor is in no way inferior in productivity to its European counterparts. And sometimes even surpasses them. Over the years, the Minsk tractor has gained a reputation as “indestructible equipment”, which cannot be affected by off-road conditions, temperature changes, dust, heat, rain, snow and frost.

The tractor is easily aggregated with a large number of attachments. Easy to use. The developers tried to create a certain level of comfort for the driver in the cabin (as far as this word is applicable for cars developed during the USSR). The machine meets modern ergonomic standards.

Disadvantages and typical problems

Some farmers note insufficient tractor performance when cultivating large areas - from 80 hectares or more. Under heavy load, the third and sixth gears are weak. In general, the engine is insensitive to fuel quality. But if the quality of diesel fuel is poor, the diesel engine may stall and not start at all. What to do? The problem is often solved by adjusting the injectors and changing diesel fuel.

PTO tractor MTZ-82 and MTZ-80

The main purpose of this mechanism is to drive active machines that are aggregated with the tractor. Based on their location, the rear and side PTOs are distinguished. Models MTZ 80 and MTZ 82 use a combined power take-off shaft, so it can have either a dependent (or synchronous) or an independent drive.

If the drive is not synchronous, then it is connected to the engine flywheel itself, this will ensure the required rotation speed of the shaft itself, regardless of the speed at which the tractor moves, and whether the clutch is engaged or not. Also, the drive itself can have the following rotation speeds (540 and 1000 rpm) at a crankshaft speed of 2100 rpm.

As for the dependent drive, it is connected to the drive gear of the 2nd stage of the mechanical gearbox, so in this case the frequency will depend and will be 3.5 revolutions per meter of travel.

PTO adjustment

When adjusting the power take-off shaft on the MTZ-80(82), the following sequence must be observed:

After the adjustment is completed, it is necessary to return all the parts to their places in the reverse order and tighten the bolts with locknuts.

If the shaft begins to slip or it is unstable, or increased force is required to turn it on, or other similar problems, it is also necessary to adjust the band brake mechanism:

Repair of the front drive axle MTZ-82

We will consider the repair in several stages depending on those symptoms. Which can be observed. Each stage will be illustrated with detailed pictures.

If traces of grease appear on the propeller shaft flange and the main gear housing, this is the first sign that elasticity will be lost and the main gear cuff will collapse. To do this, replace the cuffs and disconnect the driveshaft. First, unscrew the castle nut and remove the cardan flange. Next, unscrew the bolts securing the main gear cup bearings and two mounting bolts. Afterwards, the drive gear is pressed into the glass and the assembly with the cuff itself is removed.

Adjusting the rear PTO control mechanism

The rear PTO control must be adjusted in the following sequential steps:

• After releasing the lock nut, tighten the thrust bolt until the lid and spring of the two cups are locked.
• Tighten the locking bolt all the way.
• Remove the thrust bolt and locknut completely from the lever, and lower the spring with its parts down.
• Disconnect the rod from the control lever.
• After tightening the installation bolt, it is necessary to synchronously fix the position of the lever, aligning the hole on the rear axle housing with the threads on the housing.
• Next you need to remove the rear axle cover.
• Screw the adjusting screws one by one until they are tight, and then unscrew them 3 turns each.
• Remove the installation bolt.
• Turn the spring assembly up, then screw the thrust bolt into the lever, pointing it with a cone into the recess located at the end of the cover until the mounting bolt can rotate easily.
• Moreover, the mounting bolt must ensure movement in relation to the cup spring cover freely.
• Fix the thrust bolt in the lever, and the mounting bolt in the cup cover, and then tighten the lock nut.
• When screwing or folding the fork onto the rod, shorten or lengthen the first one so that the distance between the rod fork and the “ON” position is control lever varied between 45 - 50 mm.
• All that remains is to reinstall all the parts that were removed after connecting the lever and rod.

PTO diagram of MTZ 80 and 82

Below we present a diagram of the drive of the rear power take-off shaft for tractors of the MTZ 80 and 82 models, and we will give its explanation.

The main mechanisms of the rear PTO include: 2-speed gearbox, drive type switch, mechanical gearbox, dependent or independent type switch.

The rotation speed of the independent power take-off shaft is switched using a clutch (5), which is installed on the shaft spline (6). And the mechanism that is responsible for this is a hexagon, it is located in the lower cover of the one-piece clutch housing.

The drive is set by switching the claw coupling of the shaft (11) using a lever (18), it is located on the floor of the cabin.

The lever (18) has 3 positions: clockwise rotation - dependent type, anti-clockwise - independent, middle position - neutral. Remember that the synchronous type should only be turned on when the engine is not running or the minimum crankshaft rotation speed, but the synchronous type only when the tractor is stopped.

Malfunctions and repair gaps

The main list of malfunctions leading to stopping the operation of the tractor and subsequent disassembly and repair of mechanisms at intervals:

1. Sometimes clutch linings slip when the main oil seal on the input shaft wears out. Oil flows between the flywheel and the driven movable disk.
2. There is no braking of the gearbox input shaft. Shifting gears is difficult or makes a grinding noise. Adjust or replace the clutch brake.
3. Spontaneous shutdown of the independent PTO rotation speed
4. Transmission oil leaks from the housing at intervals.

The overall operation of the unit depends on the condition of the support bearings of the drive power and driven PTO shafts. Due to the increase in play in the supports, the gaps in the engagement of gear blocks of the gearbox and splined joints increase, which leads to increased wear of parts, the appearance of a hum, beating during operation, and spontaneous knocking out of the PTO speed position.

To replace support bearings, shafts and gears in between, complete dismantling of the unit is required, followed by disassembly and replacement of worn parts.

Replacing oil seals in between

To replace the oil seals on the shaft supports in the front partition of the housing, the gaps on the power shaft, the driven PTO shaft and the hydraulic system pump drive axis, the following steps must be performed:

1. We remove the hood.
2. Disconnect the transfer case driveshaft.
3. Unscrew the nuts securing the unit with the motor.
4. Using the front wheels, we roll the engine away from the gap.
5. Remove the lifting mechanism with the bracket.
6. We change the seals.
7. We collect cuttings.
8. We roll up the tractor.
9. We fasten the gap.
10. Install the hood.

In the upper front support of the pump drive axis, the rubber sealing ring is replaced. The fixing bolt is unscrewed from the axle. Then remove the bushing and replace the o-ring. If the bushing and seat are broken, grind a new one of a larger size.

In the middle front support between the power shaft and the PTO drive shaft, the oil seal is replaced, clamped by a sleeve and a bushing.

The lower support is sealed with an oil seal and closed with a cup-shaped cover with four bolts.

Repair practitioners pay attention! When installing the gaps with the gearbox, before tightening the fastening bolts, you need to make sure that the splined connections of the lower shafts of the PTO gaps and gearbox do not rest against the spline. This will not create a longitudinal force on the shaft, which, when tightening the units, will squeeze out the oil seal and the shaft support cover, and will not lead to oil leakage.

The tightness of the seals between the dry clutch compartment and the lubricated part of the gap ensures the tightness of the general lubrication system of the tractor transmission and isolates the clutch friction discs from oil, which causes slipping.

Repair of the drive and speed change gear of the independent PTO

Malfunctions of the unit include knocking out the on position of the PTO rotation speed. One of the reasons is a malfunction of the spring-ball retainer of the fork on the shift axis installed in the lower housing cover.

• Remove the cover with the switching drive
• Disconnect the shift fork and axle, gaining access to the spring-ball retainer
• Inspect or replace parts of the retainer
• Reassemble the axle and fork in reverse order

Clutch brake repair

The working mechanism of the brake consists of movable and fixed disks and a rod system connected to the pedal. The surface of the discs is protected by friction linings, which, when compressed, stop the clutch and the input shaft of the unit.

Design and diagram of the MTZ-82 front axle

We will study this mechanism in full, but first we need to fully understand the circuit and devices of this mechanism. To do this, we present its complete diagram and give a breakdown of the details.

The main task of the front axle of the Belarus MTZ-82 tractor is to transmit torque from the engine to the steering front wheels. The mechanism itself consists of: transmission, front differential and wheel gearbox.

The transmission design is made of two bevel gears with spiral teeth. The drive gear (37) is placed on a tapered roller bearing (40) in the cup (39). The driven one (25) fits into the belt of the differential housing (27) and the splines, using a nut (24) it is secured against any axial movements.

We recommend at the best prices:

Works performed

During the disassembly process, faulty parts are replaced and those surfaces that are subject to the most wear are inspected.

The MTZ front drive axle is driven from the gearbox through a transfer case and a cardan drive with an intermediate support.

PTO repair for models MTZ-82 and MTZ-80

One of the main problems is sticking of the shaft control lever or difficult control of the clutch driver when switching modes. Most likely, this is a malfunction of the reinforcement mechanism (spring cup) and wear of the claw coupling. To accurately determine the breakdown, it is necessary to remove and disassemble it.

During disassembly, you must be careful and perform it strictly in a certain sequence. First, you need to move the power take-off shaft control lever to a position where the technological holes in the shift shaft lever (5) and the rear axle shift. Then the locknut (3) must be loosened and the adjusting bolt (2) must be screwed all the way into the roller shift lever, and the locking bolt (4) into the cup.

After making sure that it is well fixed, remove the glass assembly. Then we clamp it under a press and turn out the bolt (4). We replace all faulty mechanisms.

If the dog clutch is faulty, then it is necessary to disconnect the gearbox from the rear axle and replace the parts.

We adjust the tension of the tapes and the lever according to the diagram below.

If an oil leak appears from under the shank, then to replace it you need to unscrew the cuff, remove the brake band, compress the carrier and remove the retaining ring. The most important disassembly points are shown in the figure below.

He's fine. But for this you need to carefully park the car closer to the gate.

Disassembly is carried out in the following sequence: Place the car on a level surface and secure it with wheel chocks. Belarusians are valued much more! In turn, because of this, the friction discs 26 and

The axes are stopped from moving using bars. Connecting disk linings or connecting disk assemblies are replaced when worn to a thickness of less than 11 mm, and pressure disks are replaced when worn to a thickness of less than 10.8 mm. Maintenance of the wheel gear In order not to bring the wheel gear to a state where it needs major repairs, the structure must be constantly maintained.

This may require partial disassembly of the part, but it is necessary to solve the problem, otherwise the components of the gearbox may fail. In theory it should disappear. And this is important not only in terms of aesthetics and visual appeal of your car, but also for the purpose of additional protection of the body and paintwork of the car from the corrosive effects of a wide variety of salts and reagents.

We recommend: MTZ with plow

The MTZ 82 axle shaft is mounted on two tapered roller bearings 14, and the vertical shaft is supported by bearings 14 and mounted in the bore of the pipe by a pin 13, which is attached with a seal housing 44 to the body of the upper conical pair. The bearings used in them are practically the same as in the base model , except, of course, for additional equipment. At the end, it is important to check the oil level in the rear axle gearbox of the Chevrolet Niva. If there is a shortage, you need to insert a hose of a suitable diameter into the filler neck with a watering can at the end, where the lubricant is poured.

Press the cuff with the cuff flap towards the roller bearing into the oil seal race flush with the end of the race. Unscrew the nut securing the swing arm and remove the arm assembly from the swing pin. Place the disc spring onto the steering axle.

Very economical. The lower conical pair is sealed using a rubber ring, which is placed in the glass 6, as well as a lip and paronite gasket along the plane of the housing cover. The force of the steering linkage when turning the tractor is transmitted through the swing arms and steering rods to the gearbox housings, which rotate relative to the pin pipes 13 together with wheels. Gearboxes consist of lower and upper pairs of bevel gears, which also serve as joints of equal angular angular velocities. The list of bearings used in all these tractors is very similar.

They consist of pairs of bevel gears, which serve as joints of equal angular velocities. Distortions and damage to the oil seal are unacceptable. Replacing the bearing in the axle shaft of the MTZ 892 tractor, first day, beginning
