Step 1
Locate the provided handle assembly and hardware pack.
WARNING
The jaws on the 5th wheel head are spring loaded. The jaws will
open rapidly when the safety pin is removed and the handle is
moved to the unlock position. Keep hands clear of the jaws at all time.
Place the head on a flat surface upside down and slide the handle
assembly (#2) over the end of the handle mount bar on the 5th wheel head.
Step 2
Insert the latch spring (#6) into the slot on the handle mount bar
and compress slightly to allow the first M8 cap screw (#4) and
lock washer (#5) to be lifted into position behind the spring.
Step 3
With the first M8 cap screw (#4) in place behind the latch spring,
align with the threaded hole on the handle lock bar (#3) and finger
tighten. Pull back slightly on the lock bar to further compress the
spring and align the second hole with the small slot in the handle
mount bar on the head.
Install the second M8 cap screw (#4) and lock washer (#5)
through the handle assembly (#2) and into the second
threaded hole on the lock bar (#3)
Step 4
With the handle and latch plate loosely installed over the
handle mounting bar on the head, rotate the head to the
vertical position and torque the M8 bolts to 16 ft-lbs.
Complete the handle installation by inserting the
safety lynch pin, locking the handle in the tow position.
