continued
Inspection – Locking Mechanism
1. Check the operation of the fifth wheel locking mechanism using a Holland
TF-TLN-5001 (2˝ kingpin) Lock Adjustment Tool. Inspect for proper locking as
described in “Operating Instructions.”
Adjustment – Locking Mechanism
1. Using ONLY a Holland TF-TLN-5001 Lock
Adjustment Tool, lock the fifth wheel.
2. Close the locks using a Holland lock tester.
3. Check the release handle – it must be fully retracted.
4. Rotate the rubber bushing that is located between the
adjustment nut and the casting.
5. If the bushing is tight, rotate the nut on the yoke shank
counter-clockwise until the bushing is snug, but rotatable by hand.
6. Verify the adjustment by locking and unlocking several times using the Lock
Adjustment Tool; check for proper locking.
7. If there is a large amount of fore and aft movement with the adjustment tool when
verifying adjustment, check to make sure the lock is fully engaged.
Improper adjustment can cause improper locking of the fifth wheel.
If the fifth wheel does not operate properly, DO NOT USE IT!
Attempting to couple with the trailer at an improper height may result in a false or
improper coupling, allowing tractor and trailer separation which, if not avoided, could
result in death or serious injury.
Repeat the adjustment procedures or contact your nearest Holland representative for
assistance.
