Ball HitCH Coupler
Before each tow, coat the ball with a thin layer of
automotive bearing grease to reduce wear and ensure
proper operation. Check the locking device that secures
the coupler to the ball for proper operation.
If you see or feel evidence of wear, such as flat spots,
deformations, pitting or corrosion, on the ball or coupler,
immediately have your dealer inspect them to determine
the proper action to prevent possible failure of the ball and
coupler system. All bent or broken coupler parts must be
replaced before towing the trailer.
The coupler handle lever must be able to rotate freely and
automatically snap into the latched position. Oil the pivot
points, sliding surfaces, and spring ends with SAE 30W
motor oil. Keep the ball socket and latch mechanism clean.
Dirt or contamination can prevent proper operation of the
latching mechanism.
pintle Coupler anD pintle HooK
The coupler on the trailer connects to the hook assembly
attached to the hitch on the tow vehicle. The coupler, hook
and hitch transfer the towing forces between the tow vehicle
and the trailer. Before each tow, check the locking device
that secures the coupler to the pintle hook assembly.
See the coupler manufacturer’s manual for other inspection
and maintenance activities. The pintle hook lever must be
able to operate freely and automatically snap into place into
the latched position. Lightly oil the pivot points and sliding
surfaces with SAE30W motor oil to prevent rust and help
ensure proper operation of the latching mechanism.
If you see or feel evidence of wear, such as flat spots,
deformations, pitting or corrosion, on the pintle hook or
coupler, immediately have your dealer inspect them to
determine the proper action to prevent possible failure of
the ball and coupler system. All bent or broken coupler
parts must be replaced before towing the trailer.
FiFtH wHeel Kingpin
Before each tow, inspect the fifth wheel and kingpin for wear,
and coat the contact surface of the fifth wheel plate with
water-resistant lithium-base grease. If you see evidence
of wear on the fifth wheel or kingpin, immediately have
your dealer inspect them to determine the proper action to
prevent failure of the fifth wheel and kingpin system. See
the manual prepared by the manufacturer of the fifth wheel
and kingpin for other inspection and maintenance activities.
lanDing leg or JaCK
If a grease fitting is present, you must use a grease gun to
lubricate the jack mechanism. Grease the gears in the top of
hand-cranked jacks once a year, by removing the top of the
jack and pumping or hand packing grease into the gears.
