Having removed the clutch shaft from the gearbox, wash it and inspect thoroughly.
Check condition of bearings, gear teeth (wear, scores, pitting), the tightness of the 4
th
gear fit, and condition of splines.
If any defects are revealed, dismantle the clutch shaft as follows:
1. Remove the roller bearing cone.
2. Use tool 139-212-3 to press off the gear.
3. Replace all the defective parts and reassemble in the reverse order.
When pressing in the gear, the bearing and the sleeve, make sure that the gear is fitted
with its flat end towards the shaft shoulder. Lay a rubber ring between the bearing and
the sleeve. Press in the sleeve with its larger chamfer facing out.
When replacing the roller bearing, be sure to change the race pressed into the clutch
shaft rear bearing housing. Use puller 345.441-3 for pressing-out the race. When
pressing in the roller bearing race, make sure that its end face with the mark of the
Manufacturing Works is facing out. When the clutch shaft is correctly assembled, the
dimension measured along the outer faces of both bearings should be within 134 to
133.39 mm / 5.2-5.3 in.
Main shaft. Having removed the main shaft, dismantle it and wash all the parts properly.
Check condition of all the parts, paying special attention to the wear of friction surfaces,
condition of teeth of the speed gears, as well as those of the gear engaging sleeves.
The gear engaging sleeves should travel freely along the main shaft sleeves, and the
shaft sleeves should move with ease along the main shaft splines.
Replace any damaged or excessively worn parts. Lubricate the main shaft splines with
motor oil, when reassembling. Fit the oil baffles with the bore facing out.
A properly assembled main shaft, should measure 106.74 to 106.264 mm / 4.2 - 4.1 in,
along the outer faces of bushings in the assembled set of gears, and 107 to 107.14 mm /
4.2 in between the oil baffles which thrust against the ends of the main shaft.
Kickstarter shaft.
Remove the kickstarter shaft, wash and inspect it thoroughly paying attention to
condition of the pawl working edge and the gear ratchet teeth. Rounded edges of the
pawl or ratchet teeth may allow the lever to suddenly disengage.
If any defects are revealed, dismantle the kickstarter shaft, as follows:
1. Press out the shaft bushing pin by slightly knocking with a hammer against the end of
the protruding portion, remove the shaft bushing, then the gear.
2. Remove the pin and the pawl spring from the shaft;
3. Press out the pawl axle and remove the pawl.
4. Wash all the parts of the shaft and replace worn-out ones. The pawl can be used
again by reversing, if the other working edge is still sharp.
5. To reassemble the shaft, reverse the sequence of the operations given above.
