Coupling

Excavator coupling parts for aftermarket replacement and repair.

This collection includes flexible rubber couplings, CF-A and CF-H style coupling elements, aluminum inserts, hubs and related drive coupling parts used on excavators, hydraulic pumps, engines and air compressors.

To confirm the correct coupling before ordering, please check the part number, outside diameter, inner hole size, bolt hole pattern, straight-hole or step-hole type, spline or hub dimensions and photos of the old part. Couplings with similar names can have different sizes or mounting details.

If you are not sure which coupling fits your machine, send us the part number, excavator model, pump model or clear product photos. We can help compare the details before shipment.
