Transfer Carriage
11.3.3 Rear Wear Pad 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. Leave the transfer carriage completely retracted.
3. If there is no attachment on the boom, extend the
boom 2/3 of the way out to simulate the weight of an
attachment. Shut engine OFF between gap checks.
4. 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.
5. At the rear of the transfer carriage, use a feeler
gauge to check the gap (12) between the wear
pads (13) and the top of the rail (14). This gap
should not be more than 0.06" (1,6 mm) at the
tightest location. If the gap is greater than 0.06"
(1,6 mm) the wear pads require shimming.
Note: Additional shims are available by calling JLG
Parts Department at (717) 485-6472.
6. Check the thickness of the wear pads. The wear pad
has a total thickness of 0.75" (19 mm). When the
wear pad is worn down to 0.5" (13 mm) the pads
should be replaced.
11.3.4 Rear Wear Pad Shimming
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 (15) holding each wear
pad and shims to the transfer carriage (16).
5. Add the required shims (17) between the wear
pad (18) and the transfer carriage (16).
6. Coat the capscrews (15) with Loctite
®
242 (blue).
Secure in place with the two capscrews (15). Torque
capscrews to, 28 - 49 lb-ft (38 - 67 Nm).
