maintenance — TRAILERS

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

Adjustable Channel

Your trailer may be equipped with an adjustable channel (Figure 21) that allows the coupler to be raised or lowered to a desired height. Periodically check the channel bolts for damage or loosening.

Figure 21. Adjustable Channel

Wheel Bearings

Wheel bearings (Figure 22) 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.

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!

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.

Follow the steps below to disassemble the wheel hub and service the wheel bearings. See Figure 22.

„„After removing the dust cap, cotter pin, spindle nut and spindle washer, remove the hub to inspect the bearings for wear and damage.

„„Replace bearings that have flat spots on rollers, broken roller cages, rust or pitting. Always replace bearings and cups in sets. The inner and outer bearings are to be replaced at the same time.

„„Replace seals that have nicks, tears or wear.

„„Lubricate the bearings with a high quality EP-2 automotive wheel bearing grease.

Wheel Hub Adjustment

Every time the wheel hub is removed and the bearings are reassembled, follow the steps below to check the wheel bearings for free running and adjust.

„„Turn the hub slowly, by hand, while tightening the spindle nut until you can no longer turn the hub by hand.

„„Loosen the spindle nut just until you are able to turn it (the spindle nut) by hand. Do not turn the hub while the spindle nut is loose.

„„Install a new cotter pin through the spindle nut and axle.

„„Check the adjustments. Both the hub and the spindle nut should be able to move freely (the spindle nut motion will be limited by the cotter pin).
