JACK MAINTENANCE
The following procedures should be performed annually.
Side-Wind Models
• The internal gearing and bushings of the jack must be kept lubricated. Apply a small amount of automotive
grease to the internal gearing by removing the jack cover, or if equipped, use a needle nose applicator or
standard grease gun on the lubrication point found on the side of the jack near the crank. Rotate the jack
handle to distribute the grease evenly.
• A lightweight oil must be applied to the handle unit at both sides of the tube.
• If equipped, the axle bolt and nut assembly of the caster wheel must also be lubricated with the same
lightweight oil.
Top-Wind Models
• Apply a lightweight oil to the screw stem.
Figure 4-1. Lubrication Points
TRAILER WHEEL BEARINGS
Some trailers 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 bearings, remove the small rubber plug on the grease 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 nozzle of the grease gun. 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 plug when finished. 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.
