REBUILDING PROCEDURES
1. Before attempting to rebuild, review each trouble-
shooting hint on page 2 of this manual. You may
find that rebuilding is not necessary.
2.
If rebuilding is required, check the front page of this
manual to be sure you have the correct kit for the fifth
wheel you are about to rebuild.
3.
Totally disassemble and clean the top plate.
4.
Inspect the top plate for cracks and a loose lock pin
hole. If the plate is cracked, or if the lock pin hole is
elongated, the top plate must be discarded.
Do not attempt to repair or
rebuild if the top plate is cracked
or distorted, or the lock pin does not fit tightly, as
the top plate may fail or the locks may malfunction.
Failure to properly install, operate, or maintain this
fifth wheel could result in tractor and trailer
separation causing death or serious injury to others.
NOTE:
When rebuilding, use only Holland rebuilding
kits and replace all roll pins, cotter pins, springs, bolts,
nuts, and washers. Also, check the rebuild kit and
verify that all parts are present (refer to page 3).
Fifth Wheel Reassembly
Before starting to reassemble the fifth wheel, it will be
helpful to fabricate a helper block. It can be made from
hardwood or steel. Refer to
FIGURE 1
for proper dimensions.
Primary Lock Installation
1.
Install the stationary lock (
6
) in
HOLE A
in the casting,
with the large counterbore facing down (see
FIGURE 2
).
Install the lock washer (
37
) and lock nut (
19
) onto the
threaded end of the stationary lock. Tighten until
tight, but still allow the lock to rotate slightly, in order
to ensure alignment with the kingpin. The lock nut will
be tightened fully when adjusting the fifth wheel locks
later in this procedure.
