Figure 17 - Lubrication Point
TRAILER WHEEL BEARINGS
The trailer axles are equipped with a grease zerk fitting
to allow lubrication of the wheel bearings without the need
to disassemble the axle hub. To lubricate the axle bear-
ings, remove the small rubber cap, attach a standard
grease gun fitting to the grease zerk fitting and pump
grease into the fitting until new grease is visible around
the castle nut. Use only a high quality grease made
specifically for lubrication of wheel bearings. Wipe any
excess grease from the hub with a clean cloth and replace
the rubber cap when finished.
Note: It is recommended to check bearing adjustment
after the first 50 miles (80 km) to maximize bearing life.
Figure 18 - Wheel Bearing Cross Section
The minimum recommended lubrication is every 12 months or 2,000 miles (3,219 km). More frequent lubrication
may be required under extremely dusty or damp operating conditions. Every six months, or depending on usage,
check for play in each bearing by jacking up the trailer, then trying to rock the wheel. If further assistance is required,
contact Generac Mobile Products Technical Service at 1-800-926-9768.
