Maintenance Procedures
8. Verify the proper adjustment by locking
and unlocking fifth wheel several time
with lock tester. Verify that there is at
least 1/16" 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 33).
NOTE: A minimum of 1/16" free play
is critical to proper operation of
the fifth wheel.
If there is NOT 1/16" minimum freeplay
in the lock, the fifth wheel lock adjustment
pin must be rotated counterclockwise
to the next lower position. Reverify that
1/16" minimum play exists using 1/16"
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.
