Unscrew two bolts 1 and 3 fastenings of the main cylinder of the drive of coupling.
Having pulled, remove the main cylinder.
Installation
Installation is carried out to the sequences, the return to removal, taking into account the following.
When replacing the main cylinder of coupling check that the distance and from a pusher axis to a flange of the main cylinder made (114±0,5) mm (fig. 8-3).

At installation use new laying.
Before a vvinchivaniye 15 (see fig. 8-1) it is necessary to apply the kontrovochny list of D on a carving of a bolt 185.
Remove air from the hydraulic drive of coupling.
