Bumper-Level Crank Assembly Rebuild Kit for Coleman Campers
This rebuild kit is designed to repair the lower crank assembly used on Coleman and Fleetwood pop-up campers equipped with a bumper-level crank system. These systems transfer motion from the crank handle through a gear-driven assembly to the central whiffletree — raising and lowering the roof.
This kit includes the most commonly worn or damaged components within the lower crank mechanism, such as the drive shaft, hub, ratchet pawl, and associated washers and pins. It is ideal for fixing issues like:
- Slipping or unresponsive crank
- Grinding or inconsistent motion during cranking
- Worn or failed ratchet components
- Loose or damaged pressure assembly
Important: Verify Before Ordering
The complete lower crank assembly is no longer available as a full pre-assembled unit. This rebuild kit includes only the individual replacement parts listed below. Please inspect your camper’s crank assembly and ensure the parts you need are included.
Note: If you are missing the entire crank housing or additional structural components, this kit may not be sufficient.
Kit Contents:
- 1x Drive Shaft (5")
- 1x Drive Hub (7.5")
- 1x Ratchet Wheel
- 1x Ratchet Pawl with Spring (Mounting bolt not included)
- 1x Pressure Plate
- 2x Pressure Washers
- 1x Shaft Bushing
- 1x Nylon Washer & 1x Steel Washer
- 1x Hex Head Nut (Coarse Thread)
- 4x Roll Pins
Replacing all worn components at once is the best way to restore function and reliability to your lift system. However, this kit is not a plug-and-play assembly — it is a collection of parts intended for rebuilds and repairs where the main housing is still usable.
Installation: Crank & Sprocket Assembly Rebuild
Safety: Support the roof with solid props before servicing.
- Identify your crank style first — Butterfly Key, 3000 Series, 6311 Direct Drive, Chain-Drive Upper Crank, or LH Drive (identification photos and specifications are in the guide).
- Follow the Crank and Sprocket Assemblies section of the guide for your style, then set the chain tension (1"–1½" gap between chain halves).
- Tip for a roof that will not stay up: with the roof fully up, add ½–1 extra turn to re-engage a compression-style clutch — if it will not hold, rebuild the crank.
