Secure the lever through the side hatch with 20 bolts 5 and secure them with a locking plate. Place lock washer 4 and gasket on plug 5 ( ) and tighten until tight. Screw plugs 5 in the same way into the threaded holes of the remaining bosses. Install the right gear shift mechanism in the same way as installing the left gear shift mechanism.

The movement of the rollers with forks must be free, with clear fixation of the neutral and working positions. The rotation of the levers of the clamp rollers must be free, with the gear shift lever in the neutral position and in positions corresponding to the full engagement of any gear.

When the clamps are locked, movement of the gear shift rollers is not allowed, which must be ensured by adjusting the gap between the end of the clamp and the shaft using cardboard spacers 15 ( ) installed under the housing of the clamp roller. Glue ring 21 ( ) into the groove of the flange of the box body using 88NP glue. The outer end surface of the ring must be clean of glue.

Running in and testing the gearbox

Place the gearbox on the stand, fill the housing with 25 liters of tractor transmission oil (see operating instructions). Run in without load for two minutes in each gear, starting from the lowest. The rotation speed of the upper shaft of the gearbox should be 500...800 min-1.

During the break-in process, check the clutch shifts in all forward and reverse gears. Switching should occur freely, without jamming. During break-in, slight gear noise is allowed. Individual impacts, knocks and fractional rolls with increased noise are not allowed. The temperature in the gearbox after break-in should not exceed the ambient temperature by more than 50 °C. Oil leakage through the seals during break-in is not allowed.

After break-in, remove the gearbox from the stand, drain the oil and install it on a wooden floor. Cover the box bearings with parchment paper and drive wooden plugs into the grease inlet and outlet holes for the lower shaft and oil pump. Wash the oil receiver screen.

It is allowed to test the gearbox during testing of the tractor power transmission. When running the tractor, check the operation of the gear shift locking mechanism. The gearbox is run-in in all forward and reverse gears.

The movement of the rollers with forks should be easy, without jamming and with clear fixation of the neutral and working positions. The rotation of the clamp roller levers should be free, without jamming, in the neutral position of the gear shift lever and in positions corresponding to the full engagement of any gear.

Check if there is pressure in the transmission lubrication system when the transmission upper shaft rotates. If there is no pressure in the lubrication system, a ruby-colored light on the instrument panel lights up. Operating the tractor without pressure in the lubrication system is not allowed.
