Instructions
Inspect integrated
wear plates
Before each use and
every 1,000 miles
Inspect the condition of the integrated wear plates on the skid plate's top surface (#1).
When the grooves have worn flush they should be replaced. (CURT# 19269) If you prefer,
you may use a lube plate installed on your trailer's kingpin (CURT# 16722) to further reduce wear.
Lubricate the
center pivot point
Before each use
Remove the center pivot pin (#2) and apply a light coating of high-pressure wheel bearing grease.
Replace the pin and ensure it is secured with the safety lynch pin.
Torque the
M14 hex bolts
Before each use and
every 1,000 miles
Torque the four M14 leg hex bolts to 100 ft-lbs. Re-torque after initial
500 miles and every 1,000 miles thereafter and prior to each individual use.
Lubricate the
locking pawl
Before each use
Open jaws and apply a small amount of grease to the curved surface of locking pawl (#5).
Pawl will be accessible through the operating handle opening in the head side plate.
Lubricate the
jaw pivot point
Every 3,000 miles
Use a grease gun to apply grease to both zerks (#6) located on the front of each jaw.
The jaws must be in the closed and locked position for the zerks to be accessible.
Lubricate the
linkage pivot
points
Before each use
Use an aerosol applicator to spray a small amount of rust inhibitor
or lubricant on the lock handle (#7), linkage bar (#7) and pawl pivot points (#7).
Lubricate the
head pivot points
Every 3,000 miles
Use a grease gun to apply grease to both zerks (#8) located on both sides of the head.

5th wheel hitch

storage
