Do not use any fifth wheel which does not operate properly.
2. Fifth Wheel Locking Mechanism: Measure Fore-Aft Movement
A. Test the operation of the fifth wheel locking mechanism using a Holland
TF-TLN-5001, 2˝ Kingpin or TF-TLN-1500, 3-1/2˝ Kingpin Lock Tester. Inspect for
proper locking.
B. Check the adjustment of the fifth wheel locks by moving the lock tester fore
and aft when locked in the locking mechanism. Fore and aft play should be
adjusted to less than 0.06˝ (1/16˝). Adjust the fifth wheel locks as described in
Holland Publications “Fifth Wheel Owner’s Manual” XL-FW483 Rev A or
XL-FW489 Rev A for the particular type of locking mechanism. If the locks
cannot be properly adjusted due to wear, the fifth wheel should be repaired
or replaced. Your HOLLAND Distributor has parts, part kits and fifth wheel top
plates available.
Improper adjustment can cause improper locking the mechanism.
C. The trailer kingpin should also be inspected for wear and damage.
A HOLLAND Kingpin Gauge (TF-0110) is available to aid this inspection.
