Removal

Fig. 8-1. Hydraulic drive of coupling: 1 – tank; 2 – a hose of supply of liquid to the main cylinder of the drive of coupling; 3 – cranked branch pipe; 4 – laying; 5 – main cylinder of the drive of coupling; 6 – bolt, 20 N · m; 7 – sealing ring; 8 – a tube with couplings, 15 N · m; 9 – washer; 10 – plug; 11 – arm; 12 – bolt, 25 N · m; 13 – washer; 14 – a tube with couplings, 15 N · m; 15 – bolt; 16 – an arm, 17 – a protective cap; 18 – union of pumping, 4,5 N · m; 19 – working cylinder of the drive of coupling; 20 – transmission



By means of a clip press a hose of 2 (fig. 8-1) of supply of liquid to the main cylinder of coupling.

Fig. 8-2. An arrangement of bolts (1, 3) of fastening and connection of a tube (2) to the main cylinder of the drive of coupling



Unscrew the coupling and disconnect a tube from the main cylinder (fig. 8-2).
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).

Fig. 8-3. The place of measurement of distance from a pusher axis to a flange of the main cylinder: and = (114±0,5) mm



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.
