Frequently Asked Questions
Q: What equipment is the HY 4081632 roll pin compatible with?
A: The HY 4081632 is designed for Hyster electric lift truck applications. It is compatible with the W45ZHD model and other Hyster models requiring a roll pin. Verify your equipment model before ordering.
Q: What is the cross-reference part number for the HY 4081632?
A: The HY 4081632 cross-references and replaces Hyster 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: What makes the HY 4081632 suitable for high-shear applications?
A: The HY 4081632 achieves high shear strength through hardened spring steel, precision manufacturing to ASTM and sae standards, and a black oxide finish. These specifications allow the pin to withstand repeated shear stresses from lift truck mast pivots, steering linkages, and load cell connections without plastic deformation or breaking.
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 material is the HY 4081632 made from?
A: The HY 4081632 is manufactured from hardened spring steel conforming to ASTM a109/a684, sae 1070-1095 grade. It is finished with a black oxide coating to enhance durability and performance.
Q: How do I know if the HY 4081632 is the right replacement part for my equipment?
A: To ensure compatibility, verify that your Hyster lift truck or electric pallet jack model requires a roll pin. The HY 4081632 is specifically designed for Hyster equipment and replaces part number 66333. Consult your equipment manual or contact a Hyster service representative for confirmation.
