Identify the right replacement components for a Lippert Schwintek In-Wall slide-out. The in-wall design uses powered drive columns, upper and lower gear racks, motor harnesses and a synchronization controller; similar-looking systems can have different motor ratios and drive parts. Compare the original motor label, gear ratio and controller before selecting replacement parts.

Schwintek replacement parts: photos and part numbers

Compare the numbered motor, controller and bearing-block photos with your installed Schwintek system. Check the original gear ratio, label and wiring connectors.

Original Schwintek in-wall slide-out reference schematic: upper motor, upper and lower rack, common shaft, controller, harness and under-room roller
Simplified view of one H-column. A complete slide has drive components on both sides. The separate J-38 support roller is not the same as the column V-roller. The component overview shows where the drive columns, gear racks and control components are used. Match the motor and rail version before ordering.

How to identify the correct in-wall slide-out part

Before purchasing a motor or controller, record the full motor label, gear ratio, controller model and revision, and any H-column or slide variant code. Confirm the manufacturer-required motor/controller pairing. The early 229466 motor must not automatically be replaced with 236575, and the 287298 motor is a different high-torque 500:1 version. Parts that fit physically may still have incompatible drive ratios or electronics.

236575 — 300:1 in-wall slide-out motor

Lippert 236575 300:1 in-wall slide-out motor catalog product photo

Manufacturer 300:1 drive motor. Match the current versus obsolete form and controller pairing; do not treat 229466 as a drop-in substitute.

Other Schwintek drive and bearing components

Motors and controller generations

229466 — older 300:1 motor (not a presumed substitute for 236575). 326876 — 8-amp controller, which Lippert says will not replace other controller versions.

Drive and bearing parts

238893 — standard spur gear; 292435 — copper-infused spur gear; 285085 — hex spur gear; 292801 — column V-roller assembly. These are different configurations.

Shafts and couplers

238462 — aluminum shaft; 259065 — steel shaft; 295873 — hex shaft; 238461 — motor-shaft coupler (old/new designs). Match the original geometry.

Compare these part numbers with the gear-rack, shaft and motor-coupler versions installed on your slide-out.

Manufacturer service illustrations and repair cautions

Review the Lippert In-Wall Slide-Out technical document library for motor/controller compatibility, drive-column variants, rack identification, repair kits and troubleshooting. The Lippert In-Wall slide-out owner's manual (PDF) includes component drawings and dated manufacturer part-number lists; confirm revisions before ordering.

Safety: A slide room is heavy and can move unexpectedly. Do not loosen structural drive assemblies, disconnect motor restraint hardware or work under an unsupported room. Follow the manufacturer's service procedures or use a qualified RV technician for structural and electrical repairs.
