Winch Mechanical Brake

The mechanical brake generates heat when loads are
lowered and the wire cable is powered out. Avoid
overheating the mechanical brake. Overheating the
mechanical brake may result in permanent damage to, or
failure of, the brake. Replace any damaged brake
components before resuming use of the winch.

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
See Figure 4-2. Proceed as follows to lubricate the
wheel bearings:
B
Figure 4-2. Wheel Bearing Cross Section
1. Remove the small rubber plug (A) from the metal
end cap (B).
2. Attach a standard grease gun fitting to the Zerk
grease fitting (C).
3. Pump grease into the Zerk fitting until fresh grease
is visible around the nozzle of the grease gun.
4. Wipe any excess grease from the axle hub with a
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
