2. Install the spring washer on the input shaft with the concave side toward the first gear.
3. Install the input shaft in the clutch housing.
4. Clean the mating surfaces of the gearbox housing and clutch housing of dirt and install the housing on the clutch housing. Tighten the 8 mm bolts to 28 Nm and the 10 mm bolts to 45 Nm.
5. Tap the input shaft with a plastic hammer.
6. Install the collar and shaft holder of the 07GAJ-PG20101 end play tool on the input shaft and tighten the 3 bolts into the groove below the splines. Make sure they fit properly and don't pinch the splines.
7. Set the indicator dial so that the pointer lies on the outer circumference of the end of the shaft.
8. Turn the bolt clockwise and determine the gap.
Do not turn the bolt more than 60°after the pointer on the dial stops moving.
9. Clearance tolerance for 1988 model gearboxes is 0.14-0.21mm. For 1989-91 models. - 0.10-0.16 mm. If the gap does not meet the tolerance, then the entire procedure above should be repeated. Assembly should not be continued until the appropriate gap has been selected.
10. Once the clearance is correct, disassemble the transmission and completely reassemble the input shaft assembly.
