2.8.5. Removal and installation of a two-mass flywheel (cars from a manual transmission)

Fig. 2.311. Components of a two-mass flywheel: 1 – a two-mass flywheel; 2 – a special bolt; 3 – the needle bearing; 4 – an epiploon crankshaftа from outside a chain drive; 5 – a cranked shaft



Removal
Remove a check point.
Remove press a coupling disk.
Mark position of a two-mass flywheel in relation to the engine.

Fig. 2.312. Clamp installation on a two-mass flywheel


Use a clamp for untwisting of bolts (fig. 2.312).

Fig. 2.121. Проворачивание a two-mass flywheel



THE NOTE
That do not admit damage of a two-mass flywheel at removal, bolts In cannot be unscrewed pneumatic винтовертом (fig. 2.121). To unscrew bolts it is authorised only by hand.

Turn a two-mass flywheel And so that bolts have risen on the centre concerning apertures (fig. 2.121).
Watch at twisting of bolts that has not occurred залегание heads of bolts on a two-mass flywheel, otherwise the flywheel will be damaged at a twisting of bolts.

Installation
Installation is carried out in return sequence.

THE NOTE
The needle bearing is located in a flywheel, at replacement of its flywheel follows запрессовать.
For fastening use new bolts.

Rearrange a clamp for a twisting of bolts.
Establish press a coupling disk.
Establish a check point.

The inhaling moments
Flywheel to crankshaftу:
– Length of bolts 22,5 мм* – 60 Нм +90 **
– Length of bolts 35,0 мм* – 60 Нм +180 ***
– Length of bolts 43,0 мм* – 60 Нм +180 ***
* Replace bolts.
** 90 there correspond turn quarters.
*** 180 correspond to half of turn.
