Maintenance - Husky 31318 Assembly, Installation, Operation And Maintenance Instructions

1. Inspect the hitch each time before connecting a trailer, check to ensure all fasteners are tight and there are no
cracks or excessive wear on the hitch; and also make sure that the jaw mechanism moves freely. Check that
King Pin Indicator in the hitch is working correctly by pulling the handle out, then while holding the handle
forward letting it slide back into the hitch. The Jaw should not close all the way. If the Jaw closes all the way
with no King Pin in place then the hitch is defective and must be repaired or replaced. If excessive wear or
damage is found, contact your installing dealer or HUSKY technical support staff at
1-877-544-4449
2. After the first 100 miles, and at least once a year thereafter, inspect all bolts for proper tightness. Retighten
nuts if needed. All fasteners ½" diameter, torque to 75 ft-lbs.
3. Apply bearing grease to top plate before coupling, or use a lubrication plate min diameter 10", max thickness
3/16".(See Husky Dealer.)
Lubrication.
1. The moving parts of the hitch require regular lubrication. (Every 3 to 6 month). Particular attention should be
paid to the Slide Arm, Cam Track, Jaw Pivot and Indicator Mechanism. (As shown in the sketch)
2. For best use apply a White Lithium Grease liberally to all moving surfaces including Pivot Pin holding the
Head and Yoke to the Cross Beam. To ensure thorough lubrication, take the Head and Yoke off the Cross
Beam by removing the Pivot Pin and turn the Head and Yoke upside down beam to gain access to the
underneath of the Hitch. It is not recommended that the Hitch be disassembled any further than removing the
Pivot Pin. It should be noted the bolts holding the Head to the Yoke are tightened to 240 ft/lbs of torque.
Reassemble the Hitch taking care to replace the Safety Lock Pin in the Castle Nut of the Pivot Pin.
3. Alternatively the Hitch mechanism may be liberally sprayed with "Spray White Lithium Grease" (Obtainable
in Auto Part Stores) every couple of months. Note warnings on Spray Can.
4. Caution: The latch mechanism can close with heavy force. Use extreme care to keep fingers, hands,
extremities & clothing out of the path of the mechanism. Failure to do so could result in severe
injury.
5. Grease Zerk fitting periodically, located on plate side of pivot pin.
