Frequently Asked Questions
Q: What are the exact specifications of the HY 4081632 roll pin?
A: The HY 4081632 is a hardened spring steel roll pin manufactured to OEM Hyster specifications. Diameter: 3/16 inch. Length: 1-3/4 inch. Finish: black oxide. Material: hardened spring steel conforming to ASTM A109/A684, SAE 1070-1095 grade. Hardness: Rockwell C45 minimum. These specifications ensure high shear strength for critical pinned connections.
Q: What equipment is the HY 4081632 roll pin compatible with?
A: The HY 4081632 is designed for Hyster electric pallet jacks and lift truck applications. It is compatible with the W40 XL/XT series and other Hyster models requiring a 3/16 inch diameter by 1-3/4 inch length roll pin. Verify your equipment model before ordering.
Q: What is the cross-reference part number for HY 4081632?
A: The HY 4081632 cross-references and replaces Hyster OEM part number 66333. This pin is equivalent in form, fit, and function to the 66333. When sourcing this pin, reference either HY 4081632 or 66333 as the original Hyster part number.
Q: Why is the black oxide finish important and does it rust?
A: Black oxide finish provides mild corrosion resistance and helps prevent seizing in pinned connections. However, black oxide is not as durable as galvanizing or plating. In wet, salty, or humid environments, these pins can develop surface rust over time. The hardened steel substrate remains strong, but inspect for rust accumulation that could affect fitment.
Q: What makes the HY 4081632 suitable for high-shear applications?
A: The HY 4081632 achieves high shear strength through hardened spring steel (SAE 1070-1095), Rockwell C45 minimum hardness, and precision manufacturing to ASTM and SAE standards. These specifications allow the pin to withstand the repeated shear stresses from pallet jack and lift truck mast pivots, steering linkages, and load cell connections without plastic deformation or breaking.
