18:11. Starter of petrol engines

Removal and installation

 PERFORMANCE ORDER

  1. Disconnect a wire from the negative plug of the rechargeable battery.
  2. Disconnect a cable of the drive of a speedometer and gear shifting.
  3. Disconnect from a starter the socket and a wire from the plug.
  4. Turn out bolts and remove a starter.

Check and replacement of elements of the stator

Adjustment of a gap of a gear wheel

 PERFORMANCE ORDER

  1. Disconnect a starter engine wire from the plug "M".
  1. Additional wires connect plugs of the rechargeable battery to the S and M plugs.
  1. Include ignition, at the same time the gear wheel of a starter will be pushed forward.

This check needs to be executed during 10 with as, otherwise, the solenoid of the traction relay can fuse.

  1. The probe check a gap between a gear wheel and a stopper. If the gap differs from demanded, adjust it, adding or removing laying between the traction relay and a forward cover. Gear wheel gap: 0,5–0,2 mm.

Check of the traction relay of a starter

 PERFORMANCE ORDER

  1. Disconnect a starter engine wire from the plug "M".
  1. Additional wires connect plugs of the rechargeable battery to the S and M plugs.
  1. Include ignition, at the same time the gear wheel of a starter will be pushed forward. If the gear wheel does not move forward, replace the traction relay.

This check needs to be executed during 10 with as, otherwise, the coil of the traction relay can fuse.

Check of the holding winding of the traction relay

 PERFORMANCE ORDER

  1. Disconnect a starter engine wire from the plug "M".
  2. Additional wires connect plugs of the rechargeable battery to the S plug and the case of the traction relay.

This check needs to be executed during 10 with as, otherwise, the coil of the traction relay can fuse.

  1. If the gear wheel remains on the place, so the holding winding of the traction relay is damaged and, it is necessary to replace the traction relay.

Check of return of a plunger of the traction relay

 PERFORMANCE ORDER

  1. Disconnect a starter engine wire from the plug "M".
  2. Additional wires connect plugs of the rechargeable battery to the plug M and the case of the traction relay.

This check needs to be executed during 10 with as, otherwise, the coil of the traction relay can fuse.

  1. The gear wheel of a starter has to be pushed forward. After a detachment of wires the starter gear wheel quickly has to return to a starting position.

Operational tests (idling)

 PERFORMANCE ORDER

  1. For carrying out tests of idling collect the scheme shown in the drawing.
  1. Establish a rheostat cursor in such situation at which the voltmeter will show tension 11,5 B, at the same time check the current consumed by a starter, and be convinced that the shaft of a starter is turned easily and smoothly. Current: no more than 60 And.

Gear wheel with the obgonny coupling

To remove the obgonny coupling from a rotor shaft, it is necessary to remove a persistent ring previously.

Move a persistent ring to a gear wheel and remove a spring ring. Now the persistent ring can be removed from a shaft.

Check of a winding of a rotor

 PERFORMANCE ORDER

  1. Ohmmeter check conductivity between a collector and a rotor. With conductivity replace a rotor.
  1. In the special device check a rotor winding. In the presence of short circuits replace a rotor. If the steel strip attached to a rotor vibrates, so in windings of a rotor there are short circuits.
  1. Ohmmeter check conductivity between collector segments. In the absence of conductivity replace a rotor.

Check of coils of the stator

 PERFORMANCE ORDER

  1. Ohmmeter check conductivity of coils of the stator. In the absence of conductivity replace stator coils.
  1. With the coil installed in the case check conductivity between a conclusion of the coil and the case of a starter. With conductivity replace stator coils.

Check of brushes

If the brush is worn-out to the designated limit, replace it.

Check of the brush holder

Ohmmeter check conductivity between each isolated brush and a plate. With conductivity replace the brush holder.

Check of the obgonny coupling

 PERFORMANCE ORDER

  1. Check a condition of teeths of a gear wheel of the obgonny coupling and, in the presence of damages, replace it. Also check a condition of teeths of a gear wreath of a flywheel.
  1. Turn a gear wheel. The gear wheel has to be turned freely clockwise and be blocked at a provorachivaniye counterclockwise

Replacement of brushes

 PERFORMANCE ORDER

  1. Remove a worn-out brush, at the same time be careful not to damage a wattled wire.
  2. Emery paper smooth out the end of a wattled occasion to provide reliable contact it with a new brush.
  1. Solder a wattled wire.

Replacement of the back plug

 PERFORMANCE ORDER

  1. Before to remove the plug, it is necessary to measure depth of its installation.
  1. The plug can be removed by means of a stripper, as shown in the drawing.
  1. Install the new plug on previously measured depth.

Assembly of a starter

 PERFORMANCE ORDER

  1. Install the obgonny coupling on the forward end of a shaft of a rotor.
  1. Establish a persistent ring and a spring ring from the forward party of a shaft of a rotor then move a persistent ring completely to a spring ring.
  1. At installation of the lever in a forward cover pay attention to its situation. If to install the lever on the contrary, the gear wheel will be put constantly forward outside and will not be able to work properly.

Switch of blocking of ignition

Check that installation height, the free wheeling and a gap of a pin with a head and an opening under the forelock of a pedal of coupling are in normal limits.

Check of the relay of a starter

Remove the relay of a starter and check conductivity between its plugs. If conductivity does not correspond to demanded, replace the relay.

Check of the switch of blocking of ignition

Check conductivity between plugs of the switch of blocking of ignition.
