(Item 19) to remove wheel motor (Item 22) and brake
brackets (Item 12) from frame.
6. Reverse steps 1 - 6 to install the wheel motor. Tighten
nut (Item 4) to a torque of 250 - 400 ft-lb.
IMPORTANT: When disassembling hydraulic lines
make sure hydraulic plugs are placed in the open
end of the hydraulic line to prevent foreign debris
from contaminating hydraulic oil. It is also a good
idea to tag the hydraulic lines when disassembling
so they can be properly reassembled. Keep all hy-
draulic lines clean and free from foreign debris.
During replacement of wheel motor, avoid overtight-
ening fittings. Check hydraulic lines for cracks or
breaks. If a hydraulic leak should appear after re-
placement of lift cylinder, replace the fitting or line
that is leaking. Check hydraulic reservoir for level
of hydraulic fluid after replacement of lift cylinder.
