Replacement

PERFORMANCE ORDER
1) record a flywheel
2) weaken / clamp bolts evenly and on diagonal; use the directing tool A = 3176
3) reinstall the holder 10-201 in the course of tightening of bolts
Prevention

Press the disk has to contact completely with a flywheel before installation of assembly bolts.
4) for repair of coupling remove the transmission
Prevention

Press disks and clutch plates have a corrosion-resistant coating therefore it is necessary to clear only the rubbing surfaces. Otherwise service life of disks will considerably be reduced.
5) do not make efforts at installation of a press disk since it is possible to damage adjusting pins / openings

Check

PERFORMANCE ORDER
1) check regarding cracks, traces of burning and wear
2) maximum internal conicity: 0.3 mm
3) check slips and vents regarding wear, and rivets – regarding rigidity
4) check the ends of springs of a diaphragm (are specified by shooters)
