Lubricating the Lippert Electric Trailer Jack # LC285318


How do i lube the jack screw of LCI electric tongue jack. Turning it over and squirting lube did nothing.


Expert Reply:

According to the Lippert Service Manual for the Lippert Electric Trailer Jack # LC285318.

1. Before each use, inspect the Power Tongue Jack and replace if bent or damaged.
2. If wiring is connected to battery terminal, inspect at least twice each year for corrosion. Clean with a
solution of baking soda and water, then apply a thin coat of grease.
3. To avoid ground continuity concerns check the mounting bolts for secure contact and keep mounting
bolts free of corrosion.
4. Once each year, extend the jack as far as possible and clean leg. Coat the leg with a light coat of
silicone spray lubricant."

They do not offer any guidance on lubricating the jack screw and there are no manuals showing disassembly for cleaning or replacing any of the gears or internal parts.
