Operation and Adjustment
8. Verify the proper adjustment and operation by locking
and unlocking fifth wheel several times with lock tester.
Verify that there is at least 1/16" (1.5 mm) of forward
and backward play in the lock by sliding a 1/16" drill bit
between the front edge of the kingpin on the lock tester
and the front lock (radius) of the fifth wheel
(Figure 19)
.
IMPORTANT:
A minimum of 1/16" (1.5 mm) free play is
critical to proper operation of the fifth wheel.
If there is NOT 1/16" (1.5 mm) minimum free play in
the lock, the fifth wheel lock adjustment pin MUST be
rotated counterclockwise to the next lower position.
Re-verify that 1/16" (1.5 mm) minimum play exists using
1/16" (1.5 mm) drill bit as described above. Check that
the fifth wheel is properly locked.
9. Rotate lock adjustment tool from side-to-side to ensure
that the lock is not over tightened. The lock should NOT
grip the kingpin and the lock tester should rotate freely.
