8.2.5 Trailer Connection to Tow Vehicle
8.2.5.1 Coupler and Ball
The coupler on the trailer connects to the ball attached to the hitch on the
tow vehicle. The coupler, ball and hitch transfer the towing forces
between the tow vehicle and the trailer. Before each tow, coat the ball
with a thin layer of automotive bearing grease to reduce wear and ensure
proper operation; and check the locking device that secures the coupler
to the ball for proper operation.
See the coupler manufacturer’s manual for other inspection and
maintenance activities. If you do not have this manual, call Bri-Mar
Manufacturing LLC at 1-717-263-6116 for more information.
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 pocket and latch
mechanism clean. Dirt or contamination can prevent proper operation of
the latching mechanism.
When replacing a ball, the load rating must match or exceed the GVWR
of the trailer.
8.2.5.2 Ring and Pintle
The ring on the trailer connects to the pintle attached to the hitch on the
tow vehicle. The ring, pintle and hitch transfer the towing forces
between the tow vehicle and the trailer. Before each tow, coat the ring
with a thin layer of automotive bearing grease to reduce wear and ensure
proper operation; and check the locking device that secures the pintle to
the ring for proper operation.
