MAINTENANCE (TRAILER)
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 I) that allows the coupler to be raised or lowered
to a desired height. Periodically check the channel bolts
for damage or loosening.
Figure I. Adjustable Channel
Wheel Bearings
Wheel bearings (Figure II) 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 II.
Figure II. Wheel Hub Components
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 fl at 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).
