CONSUMER MAINTENANCE CHECKLIST
|
|
MONTHLY clean and grease.
|
- If the ball socket or ball clamp show any signs of unusual wear or deformation, the entire coupler should be replaced.
The ball clamp is not replaceable.
|
|
|
|
REGULARLY check the hitch and ball for wear.
|
- All mounting hardware on the hitch should be tight and any worn bolts, washers, or nuts should be replaced.
The ball should not show any signs of unusual wear or scoring. If this is present, the ball should
be replaced and the coupler socket should be checked for dirt or obstructions and a film of grease applied
to the socket.
|
|
|
|
REGULARLY oil all sliding parts of the coupler
with S.A.E. 30 oil.
|
- The primary parts this pertains to are the bolt that the ball clamp and yoke latch swivel on and the thumb
latch.
|
|
|
|
REGULARLY inspect the coupler welds.
|
- Look closely for hairline cracks and if any are visible, grind the weld off and re-weld according to the instructions
provided in the product IOM. If the coupler is bolted to the frame, inspect the mounting bolts.
Tighten them or replace if necessary.
|
|
|
|
REGULARLY inspect the coupler body for any
cracks or deformities.
|
- If any exist, do not attempt to weld the cracks or straighten the body.
Replace the coupler.
|
|
|
|
REGULARLY check the latch mechanism to
see if it moves freely.
|
- If it does not, remove any obstructions. If the spring in the mechanism is damaged, replace
the entire yoke latch.
