The MTZ-82 gearbox is installed on the tractor "Belarus" (the photo is shown below). It has nine speeds. The device has only one bearing housing. The secondary shaft at the gearbox is used with 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 a crankcase with a pressure 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 are fixed with bushings. The work of the shaft is provided by the discharge mechanism. A locking mechanism is used to shift into neutral.
Switch pattern
The MTZ-82 gearbox (shift diagram is shown below) is designed for nine speeds. Reverse gear is engaged with double clutch release. The modification lever is used with a crank adapter. First gear engages without stalling. The box switches to neutral speed without much effort.
Crankcase Modification
The 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 needs to be checked 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 lining can wear off. It should also be noted that replacing the gear is quite problematic.
Injection mechanism
The pressure mechanism at the gearbox is a set of disks. Gaskets under them are selected with low elasticity. Racks are used with small ledges. The lower support in this case is securely fixed. Experts say that the supercharger can periodically clog. At the same time, a large amount of engine oil is collected on it. It needs to be cleaned periodically.
Device crankshaft
The crankshaft in the device is fixed on two supports. Linings are used only in the lower part 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 blocker is applied with a ring. Gaskets on the block are used with a small width. It should also be noted that at the topmechanism has a stem. It is secured with two fasteners. The shifter is used with a bushing.
In some cases, it may sink. In such a situation, you should immediately check the pads. Intermediate discs can also fail. It is very difficult to get them on your own. In this situation, you will have to use the help of a friend. The discs of this gearbox are closed with a cover. It is fixed on narrow clips in this model. Additionally, screws are installed in the side of the cover. Disks are removed quite difficult. In this case, the supports will have to be knocked out a little with a hammer. After that, it will be possible to inspect the bushings and evaluate the integrity of the linings on the driven gear.
Plunger mechanism
The plunger in this gearbox is used with a switch. Experts say that the pads are used in small thicknesses. The MTZ-82 gearbox is made with a gearbox on the blocker. The discs in the plunger are of small diameter. The glasses of the modification are made with overlays. There are two stems at the bottom of the plunger. Clamping mechanisms are used to fix them. Quite often, problems are observed with the blocker.
He can fly out 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. In addition, it is important to inspect the bearing housing. If they are not lubricated, there is a lot of pressure on the rods. The intermediate shaft in the gearbox is not designed for suchloads. The stems 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 block cover. To do this, you will have to disconnect only the top bar.
Device seal
The gearbox of the MTZ-82 tractor 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 the gear. Direct connection to the shaft is carried out using a rod. At the top of the mechanism is an adapter. The bushings of the modification are used of considerable width. If necessary, they can be cleaned. The top cover does not need to be removed for this.
Seal replacement
The seal in the gearbox is quite easy to change. To do this, it is recommended to first remove the crankcase. The top cover is fixed with screws. The stops in the mechanism are removed in order. It should also be noted that the seal is under the chamber. Gears must be removed with a wrench. The seal is not needed in this case. 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 stop, then it is L-shaped. It does not come into contact with the output shaft.
Saddle Inspection
The MTZ-82 gearbox is made with a saddle, which is located in the central part of the block. The clamp is located directly under the glass. Experts say that the mechanism is very easy to disassemble. Only one key is required to release the saddle. The seat cover is fixed on the clamp. Experts point out that the glasses are removed quite simply. In this case, the clamping sleeves can not be touched. At the top of the seat is the secondary screw. It is the shaft holder. To disconnect the transmission gear, you will have to hammer the rack a little with a hammer. If the MTZ-82 gearbox is very noisy, the repair of the device must begin with an inspection of the seat block.
Plunger repair
The plunger in this gearbox often breaks due to a flying support. In order to correct this situation, you must immediately inspect the rack. To do this, the cover 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, then the safety pin has deviated to the side. This is very easy to fix. There is a small retainer on the top of the block, and it has a screw. The gear unit must be screwed. The support is adjustable with a screw.
Replacing the ring
The MTZ-82 gearbox could not work without the ring, which is under the glass. Under heavy loads, it can be deformed. As a result, the central rod is locked. As a result, the gearbox is inoperative. How to get the ring? To do this is quite simple. First of all, you need to remove the protective gear and inspect the box.
Sometimes there may be foreign objects. As a rule, we are talking about screwedscrews. They often block the work of the glass and rub against the ring. The sleeve near the mechanism is removed with a key. The glass must be tapped with a hammer towards the gearbox. The ring comes off pretty easy. After replacing it, you will have to reinstall the screw and securely clamp the box.
Inspection of the second gear
The MTZ-82 gearbox works with a second speed gear, and it is fixed above the central shaft. The disc is behind the hub. Fixing of a detail is carried out on a short rack. How to remove second gear? This can only be done by first fixing the gearbox.
After that, the cover is pulled back and the screw is unscrewed. Next, you need to remove the cover and inspect the condition of the plate. In this case, the top plate should not be touched. The gear must be carefully tapped with a hammer towards the gearbox. Next, it will be possible to detach the clamping rod. After that, it remains only to remove the gear. To put it in its original place, you will 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.
Repair adapter
The MTZ-82 gearbox has an adapter located at the bottom of the oil seal. Sometimes it gets dirty or flies. To this end, it is necessary to prepare first of all a set of keys. Additionally, you will need a clamp and a hammer. First you just need to detach the cover and then stick out the gasket. shaft stuffing boxin this case, you do not need to touch.
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 inspect the bottom of the adapter. If the problem is dirt, the dust can be removed with a cloth. When replacing the adapter, it is important to pay attention to the diameter of the fastening mechanism.
