Rebuild Procedures
5. Lock Installation
1.
Lubricate the lock pin holes of the lock jaws with Never-
Seez (provided with the kit) (Figure 9).
IMPORTANT: Only use Never-Seez when lubricating the
lock pin holes of lock jaws. DO NOT use a
substitute lubricant.
2.
Attach the lock spring onto the lock jaws and force them
closed, extending the lock spring (Figure 9).
3.
Slide the closed lock jaws into the top plate casting,
lining up the lock pin holes of the lock jaws with the lock
pin holes in the casting. Be sure to position the lock jaws
with the kingpin guides facing away from the casting
(Figure 9). The yoke will hold the locks closed once they
are in place.
4.
With the lock jaws properly positioned in the casting,
drive the lock pins up from underneath the casting,
through the aligned lock pin holes of the casting and
lock jaws until the heads are flush with the casting
(Figure 10).
NOTE: The spring on the lock jaws may pull the lock pin
holes out of alignment when installing the lock
pins. If needed, insert a bracket pin through the
lock pin holes from the top to align the lock pin
holes while installing the lock pin from the bottom.
5.
Install the lock pin washers and M27 x 3 lock nuts onto
the lock pins to secure (Figure 10). Torque to 140-160
ft-lb (190 to 217 N•m). Use the hex feature on the end
of the lock pins to hold the lock pin stationary while
torquing the lock nut.
