Rebuild Procedures
2. Completely remove and discard all components for both
top plate versions EXCEPT the lube plates, bottom plate, and
handle support bracket along with their connecting hardware.
Refer to the exploded view illustrations and parts lists for
component identification.
IMPORTANT:
DO NOT remove the pocket inserts unless
they are cracked or worn. Refer to Section 9
for inspection information.
NOTE:
Lock pin and adjustment pins could be difficult to
dislodge and could require force to remove.
DO NOT hit steel parts with a steel
hammer as parts could break, sending
steel fragments flying in any direction
creating a hazard which, if not avoided,
could result in minor to moderate injury.
3. Thoroughly steam clean remainder of top plate.
4. Inspect fifth wheel top plate for cracks and flatness.
Fifth wheels with cracks MUST be replaced. The lock pin
and adjusting pin on FWAL Series are slip fit. They are
not designed to be press fit like other HOLLAND
®
fifth
wheels. However, if either hole is elongated, the top
plate must be replaced.
NOTE:
The maximum allowable lock pin hole diameter
is 1.426" (36.30 mm). The maximum allowable
adjusting pin hole diameters are 1.672" (42.47 mm)
(top) and 1.172" (29.77 mm) (bottom).
Failure to replace fifth wheels with
cracks, elongated lock pin or adjusting
pin holes could result in tractor trailer
separation which, if not avoided, could
result in death or serious injury.
