Transmission MTZ-82 for the tractor "Belarus": the gearshift and the device

A MTZ-82 transmission is installed on the Belarus tractor (photo below). It is designed for nine speeds. The device has only one bearing seat. The secondary shaft at the gearbox is of a small width. Also among the features worth mentioning are quality pads. In order to disassemble the gearbox in detail, it is recommended to study the modification device.

Box device

Transmission MTZ-82 in a section is a set of gears and a crankcase with a discharge mechanism. The drive shaft is mounted on the unit. The plunger mechanism in the gearbox is used with the stuffing box. The crankshaft is mounted at the bottom of the gearbox. Gear gears are fixed with bushes. The work of the shaft is provided by the discharge mechanism. To switch to neutral gear, a locking mechanism is used.

Switching scheme

The MTZ-82 transmission (the switching scheme shown below) is designed for nine speeds. The rear gear is engaged with a double clutch survivor. The lever at the modification is used with a cranked adapter. The first gear turns on without sinking. At a neutral speed, the box switches without much effort.

Carter modification

The transmission MTZ 80-82 is made with a two-gear caterpillar. Experts say that the modification has strong supports. At the bottom of the crankcase is a wide block. Periodically it must be inspected. On the block there are two overlays. The lower cylinders of the device are mounted on a stand. The glasses at the modification are fixed in the side part of the block. They have wide bushings. With large loads, the pads can be erased. It should also be noted that replacing the gear is quite problematic.

The blowing mechanism

The discharge mechanism at the gearbox is a set of disks. Gaskets for them are selected for low elasticity. Racks are used with small protrusions. The lower support in this case is securely fixed. Experts say that the supercharger can sometimes be clogged. At the same time, a large amount of engine oil is collected on it. It must be cleaned periodically.

Crankshaft of the device

The crankshaft in the device is fixed to two supports. The cover plates are only used at the bottom of the gearbox. If we consider the top of the mechanism, then there is a wide block. The support is L-shaped. In the central part of the modification there are two gears. The blocking device is used with a ring. Gaskets on the block are of small width. It should also be noted that the top of the mechanism has a rod. It is fixed by means of two latches. The gear selector is used with the bushing.

In some cases, it may fall. In this situation, you should immediately check the lining. Intermediate discs can also fail. Getting them yourself is very difficult. In that situation, it is necessary to take the help of a friend. The discs of this gearbox are closed with a lid. It is fixed in this model on narrow terminals. In addition, screws are installed in the side of the cover. Disks are removed quite difficult. In this case, the support will have to be slightly hammered. After this, it will be possible to inspect the bushings, and evaluate the integrity of the lining on the driven gear.

Plunger mechanism

The plunger of this gearbox is used with a switch. Experts say that the lining is of low thickness. The gearbox MTZ-82 is made with a reducer on the blocker. The discs in the plunger are of small diameter. Glasses in the modification are made with overlays. At the bottom of the plunger there are two stem. Clamping mechanisms are used to fix them. Quite often problems are observed with the blocker.

He can fly the bar. This is due to overloads on the central part of the rod. To put the bar in place, it is recommended to twist the plunger cover beforehand. It is also important to inspect the bearing housing. If they are not lubricated, the rod is subjected to a lot of pressure. The intermediate shaft in the gearbox is not designed for such loads. Stocks in this model is quite easy to get. In this case, the reducer is not required to be removed. It should also be noted that the rods can be disconnected through the cover of the unit. To do this, you only need to detach the top bar.

The gland of the device

The MTZ-82 tractor gearbox is installed with an oil seal above the block. On the sides of the mechanism are gears. In the central part of the modification there is only one disk. Also it should be noted that the stops are made with small racks. Experts say that the stuffing box works on the gear. Direct connection to the shaft is carried out with the help of a rod. At the top of the mechanism is an adapter. The bushings of the modification are of considerable width. If necessary, they can be cleaned. To do this, remove the top cover.

Seal replacement

Seal in the gearbox is quite easy to change. For this, it is recommended to first remove the crankcase. The top cover is fixed to the screws. The stops in the mechanism are removed in order. Also it should be noted that the seal is under the camera. Gears must be removed with a key. Omentum in this case is not needed. In the lower part of the gearbox there is also a seal. It is fixed on the roof of the unit. If we consider the central stop, then it is L-shaped. With the secondary shaft, it does not touch.

Inspection of the saddle

The MTZ-82 transmission is made with a saddle, which is located in the central part of the block. The clamp is directly under the glass. Experts say that the mechanism is very easy to disassemble. To disconnect the seat, only one key is required. The seat cover is fixed to the clamp. Experts point out that the glasses are removed quite simply. At the same time, the clamping bushings can not be touched. At the top of the seat is a secondary screw. It is the fastening of the shaft. To disconnect the transmission gear, you will have to hammer the rack slightly. If the gearbox MTZ-82 is very noisy, the device must be repaired with a saddle block inspection.

Repair of plunger

The plunger in this gearbox often breaks due to the departing support. In order to remedy this situation, we must immediately inspect the rack. To do this, the lid is removed and the lining is carefully removed. In this case, the secondary shaft does not need to be removed. If the support is at an angle, then the protective pin has deflected to the side. This is very easy to fix. In the upper part of the block there is a small clamp, and it has a screw. The gear unit must be unscrewed. The support is adjusted with a screw.

Replace the ring

The MTZ-82 transmission could not work without the ring, which is under the glass. At high loads, it can be deformed. As a result, the central rod is locked. As a result, the gearbox is in an inoperative condition. How to get the ring right? It is quite easy to do this. First of all, you need to remove the protective gearbox and inspect the box.

Sometimes there may be extraneous premedies. As a rule, we are talking about screwed screws. They often block the work of the glass and rub against the ring. The bushing near the mechanism is removed with a key. The glass must be hammered in the direction of the reducer. The ring is removed quite simply. After replacing it, you have to re-install the screw and secure the box securely.

Inspection of the second gear gear

The MTZ-82 gearbox operates with a gear of the second speed, and it is fixed above the central shaft. The disk is behind the bushing. The workpiece is fixed on a short rack. How do I remove the gear of the second gear? This can be done only after fixing the gearbox.

After this, the cover is loosened and the screw is unscrewed. Next, you need to remove the lid and inspect the condition of the plate. In this case, the top plate should not be touched. Gear must be gently hammered in the direction of the reducer. Then it will be possible to disconnect the clamping rod. After that, it remains only to remove the gear. To put it in its original place, you'll have to ask for help from a friend. It is problematic to install a part. In this case, it is important to hold the side sleeve.

Repair Adapter

The MTZ-82 transmission has an adapter, which is located in the lower part of the stuffing box. Sometimes it gets dirty or flies. To this end, it is necessary to prepare a set of keys first. Additionally, you need a clamp and a hammer. First you just need to detach the lid and then stick out the gasket. The shaft of the stuffing box in this case does not need to be touched.

Most experts say that the adapter should be removed from the sides of the plate. At this stage it is important to monitor the position of the gear. In the gearbox they are fixed to the stop. Next, you'll have to look at the bottom of the adapter. If the problem is contamination, the dust can be removed with a rag. When replacing the adapter, it is important to pay attention to the diameter of the fastening mechanism.
