4.1.16. Removal and installation of a flywheel / driving disk

Removal

 PERFORMANCE ORDER

1. The car also establish to Poddomkratta it on props. Remove the transmission (see the Head Korobk of gear shifting).
2. On models remove coupling assembly from RKPP (see the Head Stsepleniye and power shafts). At once check a condition of components of coupling and the directing bearing.

3. Turn out bolts of fastening of a flywheel / a driving disk to a bent shaft (see an accompanying illustration). If in the course of weakening of bolts the shaft begins to be turned, remove a starter (see the Head Elektrooborudovaniye of the engine) and jam the screw-driver between teeths of a wreath of a flywheel (RKPP), or pass a long drift throughout one of openings of a driving disk, having rested it against a ledge on the block (AT).

4. Remove a flywheel / a driving disk from a bent shaft.

The flywheel / a driving disk is rather heavy component – it will be reasonable to resort to the help of the assistant.


5. Carefully wipe a flywheel, having completely removed from it traces of oil and lubricant. Check a working surface of a flywheel for existence of cracks, the furrows left heads of rivets of a frictional clutch plate, traces of an overheat and zadir. Minor defects can be eliminated by means of a fine-grained emery paper. Check a gear wreath for existence of cracks and chips of teeths. Lay a flywheel on a flat surface for the purpose of assessment of its planeness (use the planeness measuring instrument).
6. Wipe the interfaced flywheel surfaces / a driving disk and a bent shaft. If signs of leak of oil through a back epiploon of a bent shaft take place, make its replacement (see Replacement of a back epiploon of a bent shaft).

Installation

 PERFORMANCE ORDER

1. Establish a flywheel / a driving disk on a bent shaft.

On some engines the directing pin is provided, or fixing openings are located asymmetrically that guarantees unambiguity of landing of a detail. Before rolling fixing bolts, grease from a carving part with the fixing sealant.


2. Having blocked a flywheel / a driving disk from a provorachivaniye (see paragraph 3), tighten fixing bolts with the required effort in a diagonal order.
3. Further installation is made as it should be, the return to a dismantle order.
