Keep your slide-out running smoothly with this direct-replacement 16-tooth spur gear engineered for Schwintek in-wall slide-out systems. Whether your current gear is chipped, cracked, or worn flat, swapping it out with the correct Lippert component restores consistent, reliable slide travel without replacing the entire drive assembly.
The Schwintek in-wall slide-out system uses a rack-and-pinion style drive mechanism where small spur gears engage a continuous gear track mounted inside the slide room wall. Over time -- especially with heavy use or if the slide is operated without adequate lubrication -- these gears wear down, chip, or strip, leading to jerky movement, grinding noise, or a slide that refuses to extend or retract fully.
Lippert part 238893 is the correct 16-tooth replacement spur gear for this system. The continuous tooth engagement design delivers smooth, even power transfer from the drive motor to the gear track, restoring proper slide-out operation when the original gear is damaged.
Matches the original Schwintek spur gear tooth count for accurate gear ratio and smooth rack engagement throughout the full slide travel range.
Gear profile maintains constant mesh with the rack for consistent, jerk-free slide extension and retraction under normal load conditions.
Listed as a direct replacement under Jayco, Keystone RV, Thor, and Winnebago part numbers -- one part covers a wide range of brand-name coaches.
One gear per package. Order the quantity you need -- most Schwintek systems use two gears per slide room, one at each drive point.
Unlike traditional cable-and-pulley or hydraulic slides, the Schwintek system embeds the entire drive mechanism inside the wall of the slide room itself. Two small electric motors -- one on each side of the room -- each drive a spur gear that rides along a continuous rack gear track. This keeps the mechanism hidden, reduces external hardware, and allows for low-profile slide rooms in today's lightweight travel trailers and fifth wheels.
Because the gears are load-bearing components in direct contact with the rack under motor torque, worn or broken teeth cause immediate performance problems. Replacing just the failed spur gear is almost always faster and less expensive than replacing a motor or the entire drive assembly.
Schwintek slides have a drive motor and spur gear on each side of the slide room. If one gear is visibly worn, inspect the opposite side as well. Uneven wear can cause the slide to rack (skew) during travel. Replacing both gears at the same time restores balanced drive force and prevents a repeat service call.
This Lippert gear is sold under multiple OEM part numbers depending on which brand built your RV. If your service manual or parts list shows any of the numbers below, Lippert 238893 is the correct replacement:
Schwintek in-wall slide-outs were introduced around 2010 and have been used across many lightweight travel trailers and fifth wheels. Confirm your coach uses the Schwintek in-wall system (not a traditional under-bed or cable-drive system) before ordering. The Schwintek rack-and-pinion track is visible inside the slide room wall cavity and the motors are mounted at the upper corners of the slide opening.
Spur gear replacement is a hands-on repair that typically requires partial disassembly of the slide room wall panel to access the drive motor and gear assembly. Most experienced DIY RV owners complete this repair with basic hand tools. Key steps typically include:
After replacing the spur gear, apply a lithium-based or dry PTFE lubricant to the full length of the gear rack inside the wall cavity. Schwintek recommends periodic lubrication to reduce wear on both the rack and the spur gear. Avoid petroleum-based greases that can attract grit and accelerate wear.
