Browse aftermarket replacement parts for the Bobcat 645 skid steer loader, the upper compact frame of the classic 40-series line.
Use filters or search by OEM part number to find the right part. Compatibility details are listed on each product page.
The 645 rounded out the top of Bobcat's compact 40-series range, a step up in capacity from the 643 while staying on the small chassis. Its listings reference serials from 510511001 and above, one open range covering the run, which keeps parts matching straightforward for this model.
Like its 40-series siblings, the 645's pivot and control hardware crosses the family widely, so applications on parts here often span the 643, 653, and 743 as well. Confirm engine-adjacent parts individually, since the 645's powerplant differs from the smaller 643's.
The pivot rebuild trio anchors this catalog: weld-on bushing replacing OEM 6702958, wear bushing replacing OEM 6730997, and the fastener hardware to seat them. The vibration damper replacing OEM 6560633 and compression spring replacing OEM 6713040 refresh mounts and pedal feel, and shoulder bolts and socket head bolts replacing OEM 6728473 and 7255136 cover the fasteners that decades of service loosen or strip.
Order by the parts-manual OEM number where you have it, and send your serial number to our team when a listing needs confirming.
