This chain drive crank system is commonly located behind a rear body panel. This is the compression system and ratchet upper crank. When you turn the crank handle to the right, the brake engages within this unit. A chain then drives the lower lift and the roof raises.

Please note : Hard to raise roof issues are not fixed by replacing the crank assembly. This problem is typically caused by a failing thrust bearing. Please take a look at our products and video's covering hard to raise roof issues.

Designed to weld onto the plate to replace the entire upper crank assembly. Remove the old upper crank, and re-weld this assembly back in place. A bushing located in the mounting plate for the drive shaft makes for an easy alignment and installation.
