TRAILER MAINTENANCE

The following trailer maintenance guidelines are intended to assist the operator in preventive maintenance.

Adjustable Channel

Your LT6D trailer comes standard with a fixed 2" ball coupler.The tow bar channel provides a fastening option to place other couplers (height-adjustable 2" ball and height adjustable pintle/eye - Figure 31) that can be raised/lowered to a desired towing height. Periodically check the channel bolts for damage or loosening. When ordering couplers please reference Table 10.

NOTICE

When replacing channel mounting hardware (nuts, bolts and washers), NEVER substitute substandard hardware. Pay close attention to bolt length and grade. ALWAYS use manufacturer's recommended parts when replacing channel mounting hardware.

Wheel Bearings

Wheel bearings (Figure 32) must be inspected and lubricated once a year or 12,000 miles to insure safe operation of your trailer.

If trailer wheel bearings are immersed in water, they must be replaced.

If the trailer has not been used for an extended amount of time, have the bearings inspected and packed more frequently, at least every six months and prior to use.

DANGER

If trailer wheels are under water for a long period of time, wheel bearings may fail. If this is the case, service wheel bearings immediately.

The possibility exists of the wheels falling off causing equipment damage and severe bodily harm even death!

Follow the steps below to disassemble the wheel hub and service the wheel bearings. See Figure 32.
