Starter Assembly

1. Before assembly, lubricate the screw splines of the armature shaft and freewheel hubs, gear and cover bushings with engine oil. Lubricate the driving ring of the drive with Litol-24 grease.

2. Before assembling, check the axial free play of the armature shaft by first assembling the covers, body and armature together and tightening the tie rod nuts. In this case, the anchor can be without a drive, and the front cover - without a lever.

3. The axial free play of the armature shaft of the ST-221 starter must be within

0.07–0.7 mm. Changing the amount of free play is achieved by selecting the number or thickness of shims 22 (see fig. Starter parts), located at the front end of the armature shaft.

4. For starter 35.3708, the axial free play of the armature shaft must be no more than 0.5 mm. It is adjusted by selecting the thickness of the shim 5 (see fig. Details of the back of the starter 35.3708), located between the lock washer of the armature shaft and the cover on the collector side.

5. Having picked up the shims, proceed with the assembly, which is performed in the reverse order of disassembly.

6. For starter CT-221, put insulating plastic tubes on the tie rods, and for starter 35.3708, put an insulating plastic tube on the tie bolt passing under the bus of the stator service coils.

7. After assembly, check the starter on the stand.
