4-6.2 Periodic Maintenance of the Gooseneck
Lock Mechanism:
a. The gooseneck lock mechanism should be
inspected and adjusted as necessary or every
30,000 miles. The inspection should include a
check for cracks in the top plate, elongated
attachment holes, and excessive wear or fail-
ure of component parts. Any defective parts
must be replaced before the lock mechanism
is used.
b. Close the locks and insert a 2"
"
.005 plug in
the locks.
c. Check for a tight fit. The plug should be
snug, but you should be able to rotate it by
applying some force.
d. If the plug fits loosely, tighten by rotating the
nut on the shank counterclockwise. It may be
necessary to tap the end of the yoke shank
lightly to allow the nut to seat against the top
plate
(See Figure 4-5).
e. Repeat this procedure until the plug fits
snug, but can still be rotated.
f. Use a lock tester to verify the proper opera-
tion of the locking mechanism.
