Browse aftermarket replacement parts for the Bobcat 643 skid steer loader, the compact frame of Bobcat's classic 40-series generation.
Use filters or search by OEM part number to find the right part. Compatibility details are listed on each product page.
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.
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.
Order by the OEM number from your parts manual where possible, and send your serial number to our team when a listing's range needs confirming for your build.
