11.3.5 Rear Wear Pad Replacement
Note: The attachment should remain attached to the
quick attach for this procedure.
1. Park the vehicle on 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. Leave the transfer carriage completely retracted.
3. Fully extend the boom. The attachment must remain
slightly off the ground. Turn the vehicle OFF.
4. Remove the two capscrews (1) holding each wear
pad and shims to the transfer carriage (2).
5. Replace old wear pads with new wear pads (4) and
shims (3).
6. Coat the capscrews (1) with Loctite
®
242 (blue).
Secure in place with the two capscrews (1). Torque
capscrews to, 28 - 49 lb-ft (38 - 67 Nm).
11.3.6 Front Upstop Wear Pad Check
The front upstop wear pads (5) are located under the
frame rails at the front of the transfer carriage.
Each wear pad (5) is manufactured with a convenient
wear pad indicator. This is the angled cut (6) at each end
of all wear pads.
The total thickness (7) of a new wear pad (5) is 0.625"
(16 mm). The angled cut (6) will provide a total wear
thickness (8) of 0.25" (6 mm). This will leave
approximately 0.375" (10 mm) of total unused base
material.
The pads must never be worn past the angled cut
indicator because the metal pad insert (9), that holds the
pads in place, will begin to wear into the rail surfaces. If
the pad wears past this point, the metal insert in the pad
will begin to gouge the metal surfaces.
11.3.7 Front Upstop Wear Pad Gap Check
Note: The attachment should remain attached to the
quick attach for these checks.
1. Park the vehicle on 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. Check the gap (10) between the top of the wear
pad (5) and the bottom of the rail (11). The maximum
gap should be 0.12" (3 mm).
