Disassembly
1. With a socket wrench by 10 mm unscrew the nut securing the wire tip to the terminal (contact bolt) traction relay.
2. Remove the wire tip from the contact bolt of the traction relay.
3. Using a slotted screwdriver, unscrew the two screws securing the traction relay.
4. Remove the traction relay from the starter (in this case it is necessary to disconnect the relay core earring from the upper end of the drive lever).
Recommendation: Check the ease of movement of the traction relay core. Connect an ohmmeter to the terminals of the traction relay and, by pressing the anchor to the stop, make sure that the contact bolts close (electrical resistance is close to zero). The faulty traction relay must be replaced.
5. With a socket wrench by 10 mm unscrew the two nuts of the tie rods (1) and the nut of the drive lever axle (2).
6. Using a slotted screwdriver, unscrew the lever axle.
7. Remove the axle from the cover.
8. Using a screwdriver, rest against the upper part of the front cover of the starter, pry up the drive lever support.
9. Carefully disconnect the stator from the front cover, remove the stator from the studs together with the drive shaft, drive lever, and lever support.
10. With a hammer through an open-end wrench by 13 mm knock down the starter drive travel limiter ring (in this case, a wooden block or a piece of thick rubber should be placed under the gearbox gear).
11. Using a slotted screwdriver, remove the drive travel limiter retaining ring from the groove in the shaft and remove the retaining ring and travel limiter ring from the shaft.
12. Remove the drive assembly with the lever and clutch from the shaft.
Recommendation: Check the condition of the drive. The drive should move freely along the shaft splines without jamming. The drive gear should rotate freely in one direction only, chipped teeth and strong nicks on the lead-in part of the teeth are unacceptable. Minor defects can be removed with a diamond file or an abrasive stone. A faulty and heavily worn drive must be replaced (or starter assembly).
13. Using a puller, remove the retaining ring of the drive lever coupling.
14. Remove the retaining ring (6), washer (5), coupling (3) assembled with the drive lever (4) and washers (2) from the drive (1).
Note: When replacing only the drive, further work on disassembling the starter can be omitted.
15. Using a Phillips screwdriver, unscrew the two screws securing the cap.
16. Remove the cap and gasket.
17. Using a slotted screwdriver, pry up and remove the retaining ring.
18. Remove the adjusting washers from the shaft.
19. Remove the back cover and spacer washer.
20. Remove the outer part of the brush guide.
21. Remove the front support of the anchor shaft.
22. Using a thin slotted screwdriver, pry up...
...and we take out the four brush springs.
23. Overcoming the force of the magnets, we remove the anchor from the stator.
24. Check the collector and armature windings (for more details, see. "Starter 5712.3708 and its modifications").
Assembly
We assemble the starter in the reverse order of disassembly. Before installing the drive, dip it in engine oil and let the oil drain. We lubricate the bushings in which the anchor and drive shafts rotate, as well as the screw splines of the drive with engine oil.
Before installing the starter, make sure it is working properly (see the beginning of the section).
