One New Aftermarket Replacement Retainer Plate for Caterpillar (Cat) Construction Equipment
This retainer plate is an internal hydraulic pump component used in Caterpillar (Cat) construction and mining equipment. Retainer plates in axial-piston hydraulic pumps hold the piston shoe assembly against the swash plate, maintaining proper alignment and pressure during pump operation. Replacing a worn or damaged retainer plate restores correct hydraulic pump function and prevents further internal damage.
