Install the bracket onto the reverse idle gear axle.
Screw a stud 118x10 mm in size into the threaded hole of the bracket for the axis of the intermediate gear of the reverse gear parallel to the axes of the gear blocks (pic. 4-42).
Apply a coat of sealant to the mating surfaces of the clutch housing and gearbox housing. Attach gearbox housing with mounting bolts to clutch housing. Aligning the holes of the gearshift forks with the holes for the fingers of the forks, using a screwdriver inserted into the hole in the gearbox housing for the gearshift drive, insert the fingers of the forks and tighten the bolts of their fastening (pic. 4-43). Make sure the shift mechanism is in the neutral position. Insert the gearshift drive shaft into the hole in the gearbox housing, making sure that the shaft pin enters the inner driver, and the shaft protrusion is 8 the crankcase cutout (pic. 4-44).
Install the fastener cover. Hand-tighten the outer bolt of the bracket for the reverse intermediate gear axle, unscrew the previously wrapped stud, tighten the inner bolt of the bracket and tighten the bolts, starting with the outer bolt.
On a five-speed gearbox, use a suitable mandrel to press the driven gear of the 5th gear onto the output shaft. Install the retaining sleeve and tighten the mounting bolt. Press the needle bearing and 5th gear onto the input shaft (pic. 4-45). Install the synchronizer blocking ring on the 5th gear cone and check the degree of wear of the blocking ring with a feeler gauge.
Using a suitable mandrel, press on the 5th gear synchronizer as follows. so that the hub shoulder and the pointed teeth of the sliding clutch face the 5th gear. Starting with gearbox no. 03050, the 5th gear synchronizer sliding sleeve is made with a shoulder (pic. 4-46). This coupling is interchangeable with the previous design.
At the same time, turn on the V gear and any other gear, wrap the bolts in the shaft shanks and tighten them with a torque of 4.0 kgf·m. Install the 5th gear fork and tighten the two fork mounting bolts. Adjust the V gear engagement drive (pic. 4-47). To do this, turn on the 5th gear using the sliding clutch, loosen the drive bracket bolt, insert two probes 1.2 mm thick in two diametrically opposite places between the sliding clutch and the 5th gear gear, set the gearshift drive to the 5th gear position, acting as a lever with a screwdriver, press the bracket towards the synchronizer and tighten the bracket bolt. Disengage the 5th gear and make sure that the spring and the synchronizer blocking ring are mobile.
Connect the gearbox housing to the clutch housing by installing a sealing gasket and tighten the fastening bolts to a torque of 2.5 kgf·m, then tighten them by 90°.
Using a suitable mandrel, press a new oil seal into the clutch release bearing guide bushing and lubricate the seal lips with oil.
Slide a new O-ring onto the clutch release bearing guide bush and fix it with grease, then install the guide bush onto the clutch housing.
Install the speedometer drive gear.
Using a suitable mandrel, press the oil seals into the housings of the differential housing and fill the space between the oil seal lips with grease.
Install new circlips on the differential output shafts and insert the output shafts into the differential side gear splines.
Pour oil into the gearbox and tighten the plug of the oil filler and control holes (pic. 4-48).
