MTZ-82 gearbox for the Belarus tractor: gearshift scheme and devices

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

Box device

Transmission MTZ-82 in the context is a set of gears and crankcase with a delivery mechanism. The drive shaft is mounted on the block. The plunger mechanism in the gearbox is used with an oil seal. The crankshaft is mounted at the bottom of the gearbox. Gears gears are fixed with bushings. The shaft is provided by a discharge mechanism. To switch to neutral gear, a locking mechanism is used.

Switching circuit

MTZ-82 gearbox (shift pattern shown below) is designed for nine speeds. The reverse gear is engaged with a double clutch release. The lever of the modification is used with a cranked adapter. First gear engages without retraction. The gearbox switches to neutral speed without much effort.

Carter Modifications

MTZ 80-82 gearbox is made with a crankcase for two gears. Experts say that the modification has strong supports. A wide block is installed at the bottom of the crankcase. It must be inspected periodically. There are two pads on the block. The lower cylinders of the device are mounted on a stand. The glasses of the modification are fixed in the side of the block. They have wide bushings. Under heavy loads, the linings may wear out. It should also be noted that replacing the gear is quite problematic.

Delivery mechanism

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

Device crankshaft

The crankshaft in the device is fixed on two bearings. The linings 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 installed L-shaped. In the central part of the modification, two gears are installed. The lock is applied with a ring. Gaskets on the block are of small width. It should also be noted that in the upper part of the mechanism there is a stock. It is fixed using two clips. Gear shift used with bushing.

In some cases, it may sink. In this situation, immediately check the pads. Intermediate discs can also fail. Getting them yourself is very difficult. In that situation you will have to take the help of a friend. The disks on this gearbox are covered by a cover. This model is fixed on narrow clamps. Additionally, screws are installed in the side of the cover. Disks are removed quite difficult. In this case, the supports will have to be slightly knocked out with a hammer. After that, it will be possible to inspect the bushings, and evaluate the integrity of the pads on the driven gear.

Plunger mechanism

The plunger for this gearbox is used with a switch. Experts say the pads are thin. The MTZ-82 gearbox is made with a reducer on a lock. Disks in the plunger are used small diameter. The glasses of the modification are made with overlays. There are two rods at the bottom of the plunger. Clamping mechanisms are used to fix them. Quite often, problems are observed with the blocker.

He can fly the bar. This happens due to overloads on the central part of the rod. To put the bar in place, it is recommended to twist the plunger cover in advance. Additionally, it is important to inspect the bearing housing. If they are not lubricated, high pressure is applied to the rods. The intermediate shaft in the gearbox is not designed for such loads. The stocks of this model are quite easy to get. In this case, the gearbox does not need to be removed. It should also be noted that the rods can be disconnected through the unit cover. To do this, only the upper bar will have to be disconnected.

Oil seal device

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

Seal replacement

The seal in the gearbox is pretty easy to change. To do this, it is recommended that the crankcase be removed first. The top cover is fixed on the screws. The stops in the mechanism are removed in order. It should also be noted that the seal is under the camera. Gears must be removed with a key. The gland in this case is not needed. There is also a seal at the bottom of the gearbox. It is fixed on the roof of the block. If we consider the central emphasis, then it is made of an L-shaped form. It does not come into contact with the secondary shaft.

Saddle inspection

MTZ-82 gearbox is made with a saddle, which is located in the central part of the block. The clamp itself is located under the glass. Experts say that the mechanism is very easy to disassemble. To disconnect a saddle, only one key is required. The seat cover is fixed to the clamp. Experts point out that glasses are removed quite simply. In this case, the clamping sleeves can not be touched. At the top of the seat is a secondary screw. It is a shaft mount. To disconnect the gear wheel, you have to knock a little stand with a hammer. If the MTZ-82 gearbox is very noisy, repair of the device should begin with an inspection of the saddle block.

Plunger repair

The plunger in this gearbox often breaks due to a flying out support. In order to correct this situation, you must immediately inspect the rack. To do this, the lid is removed and the lining is carefully removed. The secondary shaft in this case does not need to be removed. If the support is at an angle, it means that the safety pin has deviated to the side. This is very easy to fix. There is a small catch at the top of the unit and it has a screw. The gear unit must be unscrewed. The support is adjustable with a screw.

Ring replacement

The MTZ-82 gearbox could not work without the ring, which is under the glass. Under heavy loads, it can deform. As a result, the central stem is locked. As a result, the gearbox is inoperative. How to get the ring? This is pretty easy to do. First of all, it is necessary to remove the protective gear and inspect the box.

Sometimes there may be extraneous measures. As a rule, we are talking about screwed screws. They often block the glass and rub against the ring. The sleeve near the mechanism is removed using a key. The glass must be knocked down with a hammer towards the gearbox. The ring is removed quite simply. After replacing it, you will have to reinstall the screw and tighten the box securely.

Second gear gear inspection

The MTZ-82 gearbox operates with a second-speed gear, and it is fixed above the central shaft. The disc is located behind the hub. The part is fixed on a short stand. How to remove the gear of the second gear? This can only be done by first locking the gearbox.

After that, the cover slides open and the screw is unscrewed. Next, you need to remove the cover and inspect the condition of the plate. In this case, do not touch the top plate. The gear must be carefully knocked with a hammer towards the gearbox. 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 have to ask for help from a friend. Installing the part yourself is problematic. In this case, it is important to hold the side sleeve.

Adapter repair

The MTZ-82 gearbox has an adapter, which is located at the bottom of the gland. Sometimes it gets dirty or flies. For this purpose, it is necessary to first prepare a set of keys. Additionally, a clamp and a hammer are required. First you just need to detach the cover and then stick out the gasket. The stuffing box shaft in this case does not need to be touched.

Most experts say that the adapter must 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 on the stop. Next, you will have to examine the lower part of the adapter. If the problem is contamination, dust can be removed with a rag. When replacing the adapter, it is important to pay attention to the diameter of the mounting mechanism.
