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.

Clean the 

5th wheel hitch

After each use 

and before long term 

storage

For optimal service life, clean your 5th wheel hitch after each use with warm soapy water 

and dry with towels or compressed air. It is also recommended that the 5th wheel is removed 

from the vehicle or covered when not in use for extended periods of time. Spray exposed 

surfaces with a light coat of rust inhibitor before long term storage.
