Jack Maintenance

Before each use, check each jack foot for damage and
remove any mud or debris. The jacks must be clean and
in good operating condition to properly support the unit.

Trailer Wheel Bearings

The trailer axles are equipped with a Zerk grease fitting
to allow lubrication of the wheel bearings without the
need to disassemble the axle hub. Use only a high
quality grease made specifically for lubrication of wheel
bearings, such as Valvoline W615 or equivalent.
See Figure 4-2. To lubricate the wheel bearings:

grease fitting (C).
Pump grease into the Zerk fitting until fresh grease
3.
is visible around the nozzle of the grease gun.
Wipe any excess grease from the axle hub with a
4.
clean cloth and replace the rubber plug.
The minimum recommended lubrication is every 12
months or 12,000 miles (19,312 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
