Front Roller Gap Check
(50 Hour Intervals)
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 vehi-
cle OFF.
3. 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.
4. With the transfer carriage all the way retracted, use a rawhide hammer to
tap the rollers (1) against the rails (2). Check the gap (3) between the roller
and the existing shims (4) with a feeler gauge. Check both front rollers and
record the gap on each side.
5. 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 (3) between the roller and the existing shims of
each roller with the transfer carriage in this position. Record the gap of
each roller.
6. 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 (3) between the roller and the existing shims
of each roller with the transfer carriage in this position. Record the gap of
each roller.
7. 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 .06" (1,5 mm).
8. If the total gap is larger than .06" (1,5 mm), the rollers need to be shimmed.
