Dismantling

 PERFORMANCE ORDER

1. Turn off clamps 82.
2. Turn off bolts 71.
3. Uncover the case of valves 72 the case of valves 74.
4. Remove a sealing plate 73. All 12 balls are located in the case of valves, four 75 of which - plastic, other 8 76 - steel.
5. Turn off covers of the case of valves. Plugs and pistons of adjusting valves 72.2, 72.8 and 74.18 should not be mixed. The valve of switching B2 can be removed and installed when the case of valves is uncovered.


Assembly

 PERFORMANCE ORDER

Assembly is carried out as it should be, the return to dismantling. Implant the directing finger 59 into the case of valves (shooter).
