Replacement
Note: The attachment should remain attached to the

1. Park the vehicle on firm level ground. Place the
travel select lever in the (N) NEUTRAL DETENT
position, engage the parking brake switch and raise
the boom to a horizontal (level) position.
2. Fully retract the boom and fully retract the transfer
carriage. Shut the vehicle OFF.
3. Lift the boom with a hoist to remove pressure off the
front rollers. There should be a gap between the
rollers and the rails.
4. Shut the engine OFF.
5. Place an Accident Prevention Tag on both the
ignition switch and steering wheel, stating that the
vehicle should not be operated. (Refer to Section
1.5, “Accident Prevention Tag Usage.”)
6. Open the engine compartment cover. Allow the
engine, transmission and hydraulic fluid to cool.
7. 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.

locknut (10) from the front roller pin (11) and transfer
carriage (12).
9. Remove the front roller pin (11), front roller (13) and
shims (14). Count and label their positions for later
replacement.
Note: It is reccomended to replace both rollers at the
same time. Roller replacement includes bearings.
10. Inspect front rollers (13) for cracks and flat wear
spots. If front roller is damaged, replace it with a new
front roller.
