10.6.4. Starter repair

Before dismantling of a starter be convinced of its serviceability by simple checks.

1. Check ease of moving of the coupling of a drive along a shaft. Turn a drive gear wheel. It should be turned easily concerning a coupling nave in the direction of rotation of an anchor and should not be turned in an opposite direction.

2. Connect wires for "prikurivaniye" the minus plug of the storage battery removed from the car to the starter case. The second wire connect one end to the plus plug of the storage battery, and another – to a conclusion of an operating wire of the traction relay. If the traction relay is serviceable, click will be distributed and the drive coupling will be put forward. Otherwise the traction relay is subject to replacement.

3. Disconnect a wire from an operating conclusion of the traction relay and connect to the bottom contact bolt of the traction relay. The rotor of a starter should start to rotate with frequency more than 5000 ^mines-1. Otherwise repair a starter.

It be required to you: keys «on 8», «on 13», screw-drivers with a flat and crosswise edge, пассатижи with narrow sponges, a hammer, a tester, a calliper.

1. Remove a starter from the car (see. «Removal and starter installation»).

2. A key «on 13» unscrew a nut of fastening of the tire to a contact bolt of the traction relay.	3. Turn out two screws of fastening of the traction relay...

4.... also remove the relay.	5. Take from the traction relay an anchor...

6.... and returnable spring.	7. A key «on 8» turn out two coupling bolts.

8. Remove a back cover of a starter.	9. Turn out two screws of fastening to a cover of shchetochny knot...

10.... also take shchetochny knot from a cover.	11. Check moving of brushes in the case. They should move easily, without jammings. Measure height of brushes. If height of brushes it is necessary to replace less than 7 mm, shchetochny knot.

12. Examine a back cover of a starter. If the plug in a cover is worn-out or on it teases, sinks and other defects are found, it is necessary to replace the plug or a cover assembled with the plug.	13. Separate the starter case (stator) and a forward cover assembled with a reducer.

14. Remove from a stator a sealing ring.	15. Take a rotor from a stator.

16. Examine a rotor. If the collector is polluted or on it there are risks, scratches and other defects, прошлифуйте a collector a small glass skin. At a considerable roughness of a collector or a mica vystupaniya between its plates pierce a collector on the lathe and then прошлифуйте a small glass skin. Collector palpation concerning pins of a shaft should not exceed 0,05 mm. Check reliability of the soldering of conclusions of a winding of a rotor to collector plates. Examine a winding on rotor end faces, diameter of a winding should be less package of iron of a rotor. Otherwise replace a rotor.

17. Examine a condition of a gear wheel of a shaft of a rotor on absence of damages to a look забоин and roughnesses. At possibility insignificant damages remove with a fine-grained nazhdachny skin.

18. Check an anchor winding on short circuit by means of a tester included in a mode of measurement of resistance. Resistance should aspire to infinity.	19. Take a damper of a support of the lever of a drive.

20. Take an overlay of a support of the lever of a drive.

21. Take from a forward cover a drive shaft assembled with the coupling of a free wheeling.

22. Examine a forward cover of a starter and at detection of cracks replace it.	23. Remove the lever from the drive coupling.

24. Remove from axes drove three satellites.	25. Take out from an opening of a shaft of a drive a basic ball.

26. Check a drive. Teeths of a gear wheel of a drive should not have considerable wear. The gear wheel should be turned easily concerning a coupling nave in the direction of rotation of an anchor and should not be turned in an opposite direction. If teeths of a gear wheel are worn-out or damaged or the gear wheel is turned in both directions, replace details of a drive or a drive assembled.	27. Shift on an anchor shaft a restrictive ring.

28. Hook a screw-driver...	29.... also remove a lock ring.

30. Remove a restrictive ring.	31. Remove a drive gear wheel with the coupling of a free wheeling...

32.... and solar gear wheel of a planetary reducer.	33. Examine a solar gear wheel. Teeths of a gear wheel of a drive should not have considerable wear. If the basic plug established in an opening of a gear wheel, is worn-out or on it there were teases, sinks and other defects, it is necessary to replace a solar gear wheel.

34. Examine a drive shaft. On its working surfaces there should not be a considerable wear, задиров, sinks and so forth.

35. Collect a starter in sequence, return dismantling, taking into account the following features:

– grease a gear wheel of a shaft of a rotor with siliceous General Electric CG321 greasing or similar;

Prevention In use it is not necessary to grease the coupling of a drive. However it is necessary to clear it of dirt. Do not apply to cleaning of a drive of means which can wash up the greasing put in its coupling.

– grease with engine oil bearings (plugs) in which the starter rotor rotates;

– before installation of the traction relay put on the surface of the relay contacting to a cover of a starter from a drive, a thin layer of silicone hermetic.
