Disassembly
1. Loosen the fasteners (82) (refer to accompanying illustration).
2. Remove the bolts (71).
3. Remove the valve body cover (72) from the valve body (74).
4. Remove the sealing plate (73). All 12 balls are located in the valve body, four (75) of which - plastic, the rest 8 (76) - steel.
5. Turn away covers of the case of valves. Sleeves and pistons of control valves 72.2, 72.8 and 74.18 must not be interchanged. Changeover valve B2 can be removed and installed when the valve body cover is removed.
Assembly
Assembly is carried out in the reverse order of disassembly. Insert guide pin (59) into the valve body (arrow).
