Frequently Asked Questions
Q: What is the PU AA-02.3 piston and what does it do?
A: The PU AA-02.3 is a machined carbon steel piston component engineered for the hydraulic lift unit in Pallet Mule manual pallet jacks. It is the core component that reciprocates within the hydraulic cylinder to generate lifting force.
Q: Which pallet jack models use the PU AA-02.3 piston?
A: The PU AA-02.3 is the OEM piston for Pallet Mule AA5000 and AA5500 series manual pallet jacks. It mounts within the hydraulic unit assembly as a direct replacement component.
Q: What is the material construction of the PU AA-02.3?
A: The PU AA-02.3 is manufactured from machined carbon steel to Pallet Mule specifications. Carbon steel provides the hardness and wear resistance required for thousands of lift cycles within the hydraulic cylinder.
Q: What other components work with the PU AA-02.3 piston in the hydraulic unit?
A: The PU AA-02.3 piston mounts with the PU AA-03.3 washer for spacing and the PU AA-04 spring for return action. These components work as an assembly. The PU AA-76-5000 seal kit is also compatible with this piston assembly.
