One New Aftermarket Replacement Rotating Group-Pump for Caterpillar (Cat) Compactors
This aftermarket replacement rotating group-pump rebuilds or restores the hydraulic piston pump on Caterpillar (Cat) compactor models. The rotating group is the core pumping assembly inside a piston pump, consisting of a cylinder barrel driven by the pump shaft with pistons that travel in and out of the bore to generate hydraulic flow. Replacing a worn or damaged rotating group restores full pump output and hydraulic system performance, making it a cost-effective alternative to full pump replacement.
Compatible Models
Caterpillar Compactors: 825C, 826C
Associated Engine Platforms: 3406E, C11, C13, C15, C27
