Removal (Fig. 65)
1. Before removing any parts from the hydraulic sys-
tem, park the machine on a level surface, engage the
parking brake, lower the cutting units, and stop the en-
gine.
CAUTION
Before continuing further, read and become fa-
miliar with General Precautions for Removing
and Installing Hydraulic System Components.
2. Remove screw (28) and steering wheel cap (27)
from the steering wheel (5).
3. Remove steering wheel nut (6) from the steering
column assembly (15).
4. Remove screws (13) from the speed nuts (25) and
steering valve cover (16). Remove cover from the steer-
ing cover assembly (14).
5. Cut and remove cable tie (37) from the hose assem-
blies. Label all hydraulic connections for assembly pur-
poses.
Note: Three different styles of steering control valve
have been used on Greensmaster 3250--D machines.
Figure 65 illustrates machines with serial number under
220999999. Machines with serial number from
230000000 to 270999999 use four hydraulic fittings on
the control valve (Fig. 66). Machines with serial number
above 280000000 use a control valve without a steering
column (Fig. 67). Use appropriate illustration as a guide
when removing steering control valve.
6. For hydraulic hoses that attach to fittings in steering
control valve, disconnect hoses from fittings and re-
move O--rings. Allow hoses to drain into a suitable con-
tainer.
7. For remaining hydraulic hose(s) that thread directly
into control valve, disconnect opposite end of hose from
fitting on hydraulic manifold or steering cylinder. Allow
hose(s) to drain into a suitable container. Note routing of
hydraulic hose(s) for assembly purposes.
8. Remove cap screws from the steering arm cover
and steering control valve. Carefully pull control valve
with attached hydraulic hose(s) free of the machine.
9. Remove hydraulic fittings and O--rings from the con-
trol valve. Remove hydraulic hose(s) and O--rings from
the steering control valve.
10. If equipped, remove steering column assembly
from the steering control valve.
