Steering Control Unit Removal and Installation - Greensmaster 3100 (Fig. 41)
Figure 41
1. Remove six (6) capscrews (Item 21) and remove the
steering cover (Item 25).
2. Clean the outside of the steering valve and the area
around the hydraulic fittings. Disconnect the hydraulic
hoses from the steering valve (Item 24). Put caps or
plugs on all the fittings and hoses and tubes to prevent
contamination.
NOTE: To ease reassembly, tag each of the hoses to
show their correct position on the steering valve.
3. Remove the steering wheel cap (Item 9) from the
steering wheel (Item 11). Remove the locknut (Item 10)
that secures the steering wheel to the shaft. Pull the
steering wheel off the shaft.
NOTE: It may be necessary to use a jaw-type puller to
remove the steering wheel from the steering shaft.
IMPORTANT: DO NOT hit the steering shaft with a
hammer. This could damage the steering valve com-
ponents.
4. Remove four capscrews (Item 7) and lower the steer-
ing valve (Item 24) and steering column (Item 23) out of
the steering arm.
5. Reverse steps 1 - 4 to install the steering valve.
Tighten the steering wheel nut so the top surface of the
nut is flush with the top of the steering column.
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 steering valve, avoid over-
tightening fittings. Check hydraulic lines for cracks
or breaks. If a hydraulic leak should appear after
replacement of lift cylinder, replace the fitting or line
that is leaking. Check hydraulic reservoir for level
of hydraulic fluid after replacement of lift cylinder.
