8.2.3. Service of a starter
Check on the car
|
|
At refusal of a starter during start of the engine execute the checks described below. |
|
|
- Check a state and level of a charge of the battery.
- Smooth out battery plugs, paying special attention to purity of the positive plug and its clip.
- Check a state and reliability of fastening of ground contacts.
- Include head headlights and ignition. If headlights burn, but the starter does not function, it can be regarded as a sign of existence in a starting contour of short circuit. Check whether the engine or assembly of a gear wheel of a starter in a gear wreath of a flywheel is jammed (in these cases symptoms will be similar).
- If headlights do not burn and the starter does not function, check serviceability of the lock of ignition an electrical wiring for break.
- Examine an external electrical wiring on existence of signs of break. If it was not succeeded to find defects, it is necessary to remove a starter for performance of detailed diagnostics.

- Remove a starter from the car.
- Clamp a starter in adjusting situation in a vice with soft sponges (for a cover from the drive).
- Weaken a nut of the plug of a polar winding and disconnect a wire from the traction relay.
- Having drawn risk, mark the mutual provision of covers and the case.
- Give fixing bolts and remove a back face cover from a starter.
- Remove from a cover from the drive the case, an anchor and the brush holder assembled. Remember situation on the case of a sealing ring.
- Release brush springs and take brushes from the brush holder.
- Take the brush holder and an anchor from the case.
- Having drawn risk, mark position of the traction relay in relation to a cover arm from the drive.
- Give fixing bolts and remove from a cover the traction relay, a plunger, a spring, the drive lever, a rubber sealant and adjusting washers (if such are established). Try to remember the adjusting provision of components.
- Clamp a cover from the drive in a vice with soft sponges (a driving gear wheel up) and give screws of fastening of a casing of a gear wheel to a cover.
- Remove a casing and take assembly of a gear wheel from a cover
- Clamp a gear wheel in a vice with soft sponges, wring out the plug down and remove a lock ring from a gear wheel.
- Remove from a gear wheel the plug with a spring, then take a gear wheel from a clutch coupling.
- In case of need it is possible to take by means of pair of screw-drivers from a clutch coupling bearings. Remember situation bigger of them.
- In case of need remove bearings from an anchor, having used a stripper for this purpose.
- Carefully clear all components. Do not immerse the case, an anchor or a clutch coupling in solvent at all.

Check of a state
|
|
- By means of an ohmmeter check the insulator of the brush holder for conductivity existence. Connect one of device probes to a positive side of the brush holder, the second - to negative. If conductivity takes place, execute necessary repair, or replace the brush holder.
- Measure length of brushes, compare result of measurements to requirements of size tables and adjustments. In case of need replace brushes. Brushes have to slide freely in holders - check.
- Check the efforts developed by brush springs, compare results to standard requirements (see size tables and adjustments at the end of the Management). In case of need replace springs.
- Check a collector for existence of cavities and progar. Wipe with its rags moistened in gasoline and polish with a thin emery paper. In case of strong wear of the collector it is possible to clamp in a cartridge of the lathe and to pierce slightly very sharp cutter on high turns of rotation. After end of a pro-point measure the outer diameter of a collector and compare it to standard requirements (see size tables and adjustments at the end of the Management). Cut isolation between segments on the required depth.
- Connect one of ohmmeter probes to a shaft of an anchor or the core and move the second for the forming collector surface. If in any of points conductivity takes place, the anchor is faulty and is subject to replacement.
- Check polar windings for existence of conductivity between a wire of a winding and each of brushes. If conductivity takes place, the wire of polar windings is torn off.
- Connect one of ohmmeter probes to a wire of a polar winding, and the second - to the case. If conductivity takes place, it is necessary to replace polar windings with the case.
- Check teeth of a driving gear wheel for existence of signs of wear and chips.
- Make sure that the clutch coupling transfers rotation only in one direction. In an opposite direction the coupling has to be turned easily and smoothly, and all assembly has to move freely along screw shlits.

- Grease planetary gear wheels, a cogwheel with internal gearing and the drive lever high-temperature lubricant.
- Put on planetary assembly, adjusting washers and an intermediate forward cover a shaft of a driving gear wheel.
- Put on a washer and a lock ring a gear wheel shaft.
- Put on a driving gear wheel, persistent and lock rings a shaft.
- Install the lever of the drive and a driving gear wheel in a cover from the drive.
- Install a tension spring of the lever and if removed, adjusting plates on the electromagnetic traction relay. Carefully install on a cover from the drive the traction relay. Track correctness of its arrangement concerning the drive lever. Screw fixing bolts of the traction relay and tighten them with the required effort.
