Bobcat 643

Parts Compatible with the Bobcat 643 Skid Steer Loader

The 643 carried the compact end of Bobcat's classic lineup, small enough for confined sites while sharing its engineering with the larger 40-series frames. Listings reference serial ranges such as 501511001 and above, and the serial plate confirms coverage on parts that changed during the production run.

The 643's pivot and control hardware crosses widely within the classic family, so many parts here also list the 743 and 742 among their applications. Engine-side components are specific to the 643's smaller diesel, so check those application lists individually.

Common Replacement Parts for the Bobcat 643

The weld-on bushing replacing OEM 6702958 restores lift arm pivots, the vibration damper replacing OEM 6560633 and compression spring replacing OEM 6713040 refresh mounts and controls, and the rubber seal replacing OEM 6651709 is a common cab-sealing item. Fastener hardware, O-rings, and washers fill out the classic-machine rebuild pattern.
