One New Aftermarket Replacement Rotary Group (Drive) for Caterpillar (Cat) Construction Equipment
This aftermarket replacement Rotary Group (Drive) is an internal subassembly for Caterpillar (Cat) hydraulic piston pumps and motors. The rotary group is the core rotating assembly within a piston-type hydraulic pump or motor, comprising the cylinder barrel, drive shaft interface, pistons, and related components that generate hydraulic flow. Replacing a worn or damaged rotary group restores proper hydraulic output and pressure, helping get Cat equipment back to full operating capacity.
