One New Aftermarket Replacement Rotating Group - Pump for Caterpillar (Cat) Excavators
This aftermarket replacement rotating group is an internal assembly for the main hydraulic piston pump on Caterpillar (Cat) excavators. The rotating group is the core wear component of a hydraulic piston pump, consisting of a cylinder barrel, pistons with slipper shoes, and related components that generate hydraulic flow to power the boom, arm, bucket, and track drive functions. Replacing a worn rotating group restores pump output pressure and flow, reducing cycle times and recovering digging force.
