4.2.12. Service of a flywheel

Implementation of the procedures described below will require the dial measuring instrument of plunger type and a source of heat (for example a blowtorch).

For ensuring access to a flywheel it is necessary to remove the engine, or transmission from the car. The choice depends on existence of the lifting equipment.

Removal and installation

Removal

 PERFORMANCE ORDER

  1. Remove the engine or transmission.
  2. Mark situation on a coupling basket flywheel. Gradually weaken and turn out fixing bolts, remove a basket from the directing pins of a flywheel and take coupling from the car (components of coupling are shown on an accompanying illustration).
1 — bolts
2 — assembly of a basket with a press disk
3 — a diaphragm spring
4 — a frictional slip
5 — a nave
6 — the conducted disk
7 — a flywheel
  1. Block a flywheel from a provorachivaniye and turn out bolts of its fastening.
  2. Having marked the provision of a flywheel on a bent shaft, carefully remove it.

Installation

Installation is made upside-down.

 PERFORMANCE ORDER

  1. Accurately try to obtain combination of all landing tags put in the course of dismantle and tighten all fixture with the required effort (see size tables and adjustments at the end of the Management).
  2. Center the conducted clutch plate on the directing plug of a bent shaft by means of a spare main shaft of transmission or the special tool. Gradually in a diagonal order tighten bolts of fastening of a basket.

Check of a state

 PERFORMANCE ORDER

  1. Measure the size of a beating of the worker (contacting to a clutch plate) the flywheel surface. If the result of measurement exceeds 0.1 mm both on put on a bent shaft, and on the flywheel removed from it, the last should be replaced.
  2. Check a working surface of a flywheel for existence of cracks, zadir and deep scratches.
  3. Examine wreath teeth on existence of chips, cracks and other damages. The gear wreath is subject to replacement separately from a flywheel.

Replacement of a gear wreath

 PERFORMANCE ORDER

  1. Remove a flywheel from the car and drill an opening of ø of 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.

  1. Place a chisel over the drilled opening and sharp blows of the hammer split a wreath.
  2. Remove a wreath from a flywheel, then remove from a landing surface the agnails left at removal and teases.
  3. Zapoliruyte an emery paper on povit several sites a new gear wreath and begin to heat the last until the polished sites do not get a dark blue shade.
  4. Quickly put on a wreath a flywheel facets of 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 a wreath cool down in the natural way, do not pour over it water at all!
