Frequently Asked Questions
Q: What are the exact dimensions and material specifications for the HY 91527 roll pin?
A: The HY 91527 is a precision-engineered roll pin measuring 3/16 inch diameter by 1.75 inches long. It is manufactured from hardened carbon steel per SAE J429 Grade 8 with a minimum Rockwell C45 hardness rating. This roll pin is designed for press-fit retention in mechanical assemblies requiring high shear strength and dimensional precision.
Q: Which Hyster pallet jack models are compatible with the HY 91527 roll pin?
A: The HY 91527 roll pin is compatible with Hyster W40XL and W40XT electric pallet truck models. It is designed for press-fit installation into nominal 3/16 inch bore holes in mechanical retention assemblies on these platforms.
Q: What is the purpose of the HY 91527 in Hyster electric pallet trucks?
A: The HY 91527 roll pin functions as a mechanical retention fastener in control mechanisms, linkages, and structural assemblies. It is used in press-fit applications where a precision fit and high shear strength are required to prevent component movement and maintain assembly integrity under load.
Q: Is the HY 91527 roll pin durable for repeated use and field removal?
A: The HY 91527 is manufactured to Grade 8 hardened carbon steel specifications, making it durable for material handling environments. However, repeated press-fit removal and reinstallation can degrade the fit tolerance over time. For critical assemblies subject to frequent disassembly, inspect the pin bore for wear and consider replacement if the press fit becomes loose.
Q: Are there cross-reference or equivalent part numbers for the HY 91527?
A: The HY 91527 is the OEM manufacturer part number issued by Hyster. When ordering or cross-referencing, verify the exact bore diameter and length specifications (3/16 inch by 1.75 inches) to ensure compatibility with your equipment, as similar pins may differ in material grade or hardness.
