4.7.1 Valve Plate Removal
1. Park the vehicle on a firm level surface, fully retract
all hydraulic cylinders and ground attachment, (if
any). Place the travel selector lever in the (N)
NEUTRAL DETENT position, engage the park brake
switch and shut the engine OFF.
2. Place an Accident Prevention Tag on both the
ignition key switch and steering wheel, stating that
the vehicle should not be operated. (Refer to Section
1.5, “Accident Prevention Tag Usage.”)
3. If the vehicle has dual batteries, disconnect both
negative battery cables (1 and 2) from both
batteries.
To access the lower battery (3), loosen the knob (4)
far enough so that the lip (5) on the upper battery box
clears the knob. Lift up the upper battery box (6) and
swing it out, so that the box clears the hydraulic tank
support bracket, to gain access to the lower negative
battery cable (1). Disconnect the lower negative
battery cable.
4. Attach a suitable lifting device to the cab step (7) and
remove the slack.
5. Remove four capscrews (8) and washers (9) from
the cab step (7) and lower the cab step to the
ground.
6. Support the valve plate (10) with a suitable lifting
device.
7. From under the valve plate (10), remove the two
capscrews (11) and washers (12) securing the plate
to the cab mount frame (13). Lower the valve plate.
8. Disconnect the two tethers (14) from the cab mount
frame (13).
