Series 640 3/4 Ton Long Handle Puller Liftwheel

Product Description

Product Description:
This CM liftwheel is a replacement drive component for the Series 640 3/4 Ton long handle puller. CM’s official parts documentation identifies part number 40130 as the liftwheel used in the 3/4 Ton configuration.

The liftwheel engages the puller’s load chain and transfers movement from the manually operated lever and gear assembly to the chain. Its formed chain pockets help guide the links through the puller while maintaining the required relationship between the chain, chain guide, frame, and internal drive components.

This replacement component is intended for repair of a puller with a worn, damaged, bent, or contaminated liftwheel. Correct chain seating is essential because excessive pocket wear or foreign material around the liftwheel can cause binding between the chain and frame. The complete Series 640 Puller is designed for lifting, pulling, dragging, and stretching in heavy-duty construction and industrial applications.
