Assembling the gearbox

Remove the bearing rings, the remaining parts of the housing in the sockets and replace all seals. Pick washer bearing preload adjustment differential. Install the new rings without preload washers.

Install the differential in the clutch housing and connect both parts of the gearbox; tighten the bolts to the specified torque.

Measure the dial indicator axial gap differential. Disconnect the crankcase and remove the differential bearing race from the transaxle case. Set in a nest on a ring washer thickness 0.20-0.25 mm larger than the measured axial displacement differential. Replace the bearing ring. Install the input shaft, pinion reverse gear and its axle spacer (Fig. 4.39) in the clutch housing. Tighten the bearing flange of the primary shaft. Install the secondary shaft. Replace the ball and the spring retainer, drive mechanism forks, fork with shock-absorbing inserts (Fig. 4.40), the stock forks and spring (Fig. 4.41). Check ease of rotation of the shafts. Apply a layer of sealant to the mating surface of the crankcase. Connect both sides of the transmission case and tighten the bolts to 30 Nm. Remove the cover at the end of the output shaft. Remove the stuffing box, and then adjusting ring and spacer. Measure the distance using a bore gauge (A) between the ring and the bearing surface of the crankcase (Fig. 4.42). Pick the thumbwheel, the thickness of which is defined by the formula

T = A + B - B, where A - the measured distance, in millimeters;

B - 0,18-0,25 mm; B - 2.5 mm (the thickness of the spacer).

Replace the adjusting ring (Fig. 4.43), picking up his tab. 4.3 gland and cover.
