Frequently Asked Questions
Q: What does the PU AA-15 spring do in the pallet jack?
A: The PU AA-15 is a compression return spring used in the hydraulic unit of AA5000 and AA5500 manual pallet jacks. It provides spring force to return the hydraulic piston to its original position.
Q: What material is the PU AA-15 spring made from?
A: The PU AA-15 is constructed from oil-tempered spring steel with an uncoated finish. This material resists fatigue and corrosion from repeated compression cycles and hydraulic exposure.
Q: Which Pallet Mule models use the PU AA-15 spring?
A: The PU AA-15 is compatible with Pallet Mule AA5000 and AA5500 series manual pallet jacks. Both models use the same compression spring in their hydraulic assemblies.
Q: What are the cross-reference part numbers for the PU AA-15?
A: The PU AA-15 has equivalent cross-references PUAA-15, AA-15, and PTAA-15. These designations may appear in different technical manuals or supplier databases.
Q: Is the PU AA-15 included in the PU AA-76-5000 seal kit?
A: The PU AA-15 spring is compatible with seal kit PU AA-76-5000, meaning they are often serviced together. When rebuilding the hydraulic unit, verify that both components are included in your service procedure.
Q: What is the lifespan of the PU AA-15 spring?
A: Oil-tempered compression springs typically last many years under normal operating conditions. Replace the spring if it loses tension, fails to return fully, or if the jack becomes difficult to lower during operation.
