See page 16.
2. Set POWER ON/OFF on Programmable Skipline
Controller to OFF.
3. Remove two bolts (30) and washers (31 and 32)
from left and right sides of hydraulic pump.
4. Remove two bolts (13 and 115) from plate (108)
behind pump. Remove plate.
CAUTION
Dust or dirt in the hydraulic system can damage the
hydraulic system components. Do not allow dust or
dirt to get into the hydraulic system when you service
the system.
5. Disconnect three hydraulic fittings (90 and 91) on
top of reducer (valve manifold) (84).
6. Loosen clamp (94), and remove hydraulic by-pass
hose (95) at rear of reducer (valve manifold) (84).
7. Loosen clamp (67), and remove hydraulic inlet
hose (89) from hydraulic vane pump (33).
8. Loosen clamp (94), and remove hydraulic return
hose (98) from hydraulic vane pump (33).
9. Remove hydraulic vane pump (33), reducer (valve
manifold) (84), and half of coupler (16).
10. Remove nipple (82), and remove reducer (valve
manifold) (84) from hydraulic vane pump (33).
11. Remove elbow (105), adapter (106), elbow (140),
and insert (141) from hydraulic vane pump (33).
Assembly
1. Install elbow (105), adapter (106), elbow (140),
and insert (141) on hydraulic vane pump (33).
2. Install nipple (82), and install reducer (valve
manifold) (84) on hydraulic vane pump (33).
