Light switch or extend/retract switch?
Two switches sit next to each other on the jack head, but they perform different jobs. 2020104072 switches the light on and off. Part 2020102614 is the separate extend/retract control that drives the jack leg. Use the corresponding factory part number rather than selecting a switch by its black housing alone.
Side plug versus manual-override plug
The 225875 side plug closes an opening on the side of the head. The original 225876 and current 321807 manual-override plugs instead cover access to the crank drive. Lippert also identifies the current override plug under pack number 733924. Compare which opening needs a plug before replacing it.
Footpad and retaining hardware
The 165253 footpad supports the jack leg on the ground. The illustrated assembly uses a 382844 clevis pin and 118105 cotter pin to secure the pad. Check the condition of both fasteners whenever the footpad is removed or replaced.
Jack specifications and installation
- Jack model: 285318
- Rated lifting capacity: 3,500 lb
- Maximum stroke: 18 inches
- Electrical: 12V DC with a manufacturer-specified 30A fused circuit
- Lighting: four integrated LED lights

The complete 285318 aftermarket jack is supplied by Lippert with a footpad and manual crank handle. For installation, emergency manual operation and jack troubleshooting, see the Lippert Power Tongue Jack installation and owner's manual (PDF).
Chock the trailer wheels and follow the trailer manufacturer's support instructions before removing the jack or its footpad. This jack is intended to raise and lower the trailer tongue, not to act as a stand-alone trailer stabilization or under-trailer support system.
