This aftermarket replacement hydraulic pump piston assembly (Piston As-Pump) fits Caterpillar equipment across a wide range of excavator, backhoe loader, skid steer, multi-terrain loader, motor grader, challenger, cold planer, and earthmoving compactor models. The piston assembly is a core rotating group component in axial piston hydraulic pumps -- as the cylinder block turns, pistons travel in and out of the bore to generate hydraulic flow. Service note: when replacing pistons, it is recommended that all pistons in the pump be replaced at the same time.
