11.3.9 Front Upstop Wear Pad Replacement
Note: The attachment should remain attached to the
quick attach for this procedure.
1. Park the machine on a firm, level surface, level the
machine, fully retract the boom, level the boom,
place the transmission control lever in
(N) NEUTRAL and engage the park brake.
2. Leave the transfer carriage completely retracted.
3. Fully extend the boom. The attachment must remain
slightly off the ground. Turn the machine OFF.
4. Remove the two capscrews (1) holding each wear
pad (3) to the plate under the rail at the front of the
transfer carriage.
5. Coat the capscrews with Loctite ® 242 (blue). Place the
new wear pads with original shims (2) in place and
secure with the two capscrews. Torque the

11.3.10 Rear Roller Gap Check
Note: The attachment should remain attached to the
quick attach for these checks.
1. Park the machine on a firm, level surface, level the
machine, fully retract the boom and transfer
carriage, level the boom, place the transmission
control lever in (N) NEUTRAL, engage the park
brake and shut the engine OFF.
2. This procedure will require the gap check to be
made in three separate locations. Transfer carriage
all the way retracted, transfer carriage all the way
forward and the transfer carriage moved forward
about halfway.
3. With the transfer carriage all the way retracted, use a
rawhide hammer to tap the rollers (4) against the
rails (5). Check the gap (6) between the roller and
the existing shims (7) with a feeler gauge. Check
both rear rollers and record the gap on each side.
4. Start the engine and move the transfer carriage all
the way forward. Shut the vehicle OFF. Use a
rawhide hammer to tap the rollers against the rails
and again check the gap (6) between the roller and
the existing shims of each roller with the transfer
carriage in this position. Record the gap of each
roller.
5. Start the engine and move the transfer carriage
about halfway back. Shut the vehicle OFF. Use a
rawhide hammer to tap the rollers against the rails
and once again check the gap (6) between the roller
and the existing shims of each roller with the transfer
carriage in this position. Record the gap of each
roller.
6. Find the location that had the smallest gap. This is
the position that the roller gap will be adjusted to, if
necessary. The maximum total gap of both sides
should not exceed 0.08 in (2 mm).
7. If the total gap is larger than 0.08 in (2 mm), the
rollers need to be shimmed.
