Frequently Asked Questions
Q: What are the dimensions of the PU AA-27 clip pin?
A: The PU AA-27 has nominal dimensions of 1.5 inches length and 0.25 inch width. It is compatible with shaft diameters ranging from 0.1875 to 0.25 inches, making it suitable for various pivot points in the pallet jack assembly.
Q: What pallet jack models use the PU AA-27 retaining pin?
A: The PU AA-27 is designed for Pallet Mule AA5000 and AA5500 manual pallet jacks. It functions as an OEM carbon steel retaining component in hydraulic and linkage assemblies on these models.
Q: What is the material and hardness rating of the PU AA-27?
A: The PU AA-27 is manufactured from carbon steel with a hardness rating of Rockwell C40 minimum. This hardness specification ensures the pin resists bending and deformation during normal operation while maintaining tensile strength of minimum 100,000 PSI ultimate tensile.
Q: What cross-reference numbers are available for the PU AA-27?
A: The PU AA-27 can also be referenced as AA-27 or PUAA-27. These part number designations are interchangeable and refer to the same OEM hairpin-style retaining pin.
Q: What surface finish does the PU AA-27 have?
A: The PU AA-27 features a plain carbon steel surface with no coating. This finish provides the grip and friction characteristics necessary for secure retention in pivot and fastener applications.
Q: What is the function of the PU AA-27 in pallet jack hydraulic assemblies?
A: The PU AA-27 hairpin-style retaining pin secures pivot points and linkage connections in Pallet Mule hydraulic systems. It prevents components from separating under load and maintains proper alignment of the pump and valve mechanisms.
