Flywheel service / driving disk

For performance described below works the following special equipment is required: tsiferblatny measuring instrument of plunzherny type and suitable source of heat (blowtorch or gas torch).

For ensuring access to a flywheel / it is necessary for driving disk to remove either the engine, or transmission. The choice is left to the discretion of the performer depending on existence near at hand the corresponding elevating equipment.

Removal and installation



    Remove the engine, or transmission. On models from RKPP mark the adjusting provision of a basket of coupling on a flywheel. Gradually weaken and turn out fixing bolts, remove a basket from directing pins and take coupling assembly. Block from a provorachivaniye a flywheel / a driving disk and turn out bolts of its fastening (see an accompanying illustration).
1 — the directing bearing
2 — bolts
    Having marked the adjusting provision of a flywheel / a driving disk on a pin of a cranked shaft, remove it from the car.



    Installation is made upside-down. Track correctness of combination of the landing labels put in the course of dismantle. Tighten bolts of fastening of a flywheel / a driving disk with demanded effort. On models from RKPP center a conducted disk of coupling on the directing plug of a cranked shaft, having used for this purpose old primary shaft of a transmission or the special centering tool. In stages, operating in a diagonal order, tighten bolts of fastening of a basket of coupling with demanded effort.

Condition check


    Estimate size of palpation contacting to a disk the coupling/converter of rotation (working) surface of a flywheel / a driving disk. If the size of palpation both removed from a cranked shaft, and the flywheel put on it / a driving disk exceeds 0.1 mm, it is necessary to replace knot. Check a working surface of a flywheel on existence of cracks, deep scratches and задиров. Check a wreath teeth on existence of chips, cracks and operation signs.

Replacement of a gear wreath of a flywheel is possible, the driving disk - is not present!

Replacement of a gear wreath of a flywheel


    Remove a flywheel from the car and drill an opening of ø 3 mm between two teeth of a wreath.

The opening should not be through in order to avoid damage of a flange of a flywheel.

    Place a chisel over the drilled opening and sharp blows of a hammer split a wreath. Remove a wreath from a flywheel, then remove from a landing surface the agnails left at removal and teases. Zapoliruyte an emery paper some sites on повит a new gear wreath also start to heat up the last until the polished sites will not get a dark blue shade. Quickly put on a wreath a flywheel facets of a teeth up and from a flywheel flange. Make sure of reliability of landing of a wreath and density of its pressing to a flange.

Let's to a wreath cool down a natural way, at all do not pour over it water!
