  • - control lamp,
  • - screwdriver,
  • - spanners 10, 13 and 17 mm,
  • - pliers.


Step 1

In preparation for the remanufacturing of the starter, it is necessary to establish the cause of its failure. For this purpose, a control lamp is connected to the battery, and after turning the key in the ignition lock to the "Starter" position, the degree of heating of its spiral is visually determined.

Step 2

If the light from the lamp dims, then this fact indicates that there is a short circuit in the armature windings. Restoring the starter's performance in case of such a malfunction may require rewinding the rotor coils of the device, which is almost impossible in a garage. Therefore, it is better to replace it with a new one.

Step 3

When, after turning the key, the glow of the spiral at the lamp does not weaken, then the cause of the malfunction lies in the retractor relay.

Step 4

To carry out repairs, the on-board network is de-energized by removing the ground cable from the battery. The starter is dismantled from the engine and placed on the workbench. Then, using a 13 mm key, the bus connecting the power windings is disconnected from the rear cover of the solenoid relay.

Step 5

A screwdriver unscrews three bolts of the solenoid, its tip is disengaged from the clutch fork that moves the drive gear, after which the electromagnetic coil is dismantled from the starter.

Step 6

Restoring the working capacity of the solenoid relay is reduced to repairing its contacts located in the back cover. After flaring the housing of the solenoid coil, access to the copper bolts and the solenoid ring is opened.

Step 7

The tightening of the bolts, simultaneously performing the functions of contacts, is loosened, then they are turned half a turn around their axis, and tightened.

Step 8

Further, the retaining ring is removed from the solenoid axis, due to which it becomes possible to turn the copper "penny". After changing the plane of its fit, it is again fixed in its original place.

Step 9

By inserting the ebonite cover into the solenoid body, its edges are rolled up, and the solenoid relay is mounted on the starter. After checking, it is installed on the engine.
