Frequently Asked Questions
Q: What are the material and hardness specifications of the HY 91526 roll pin?
A: The HY 91526 is constructed from spring steel per SAE J403, specifically SAE 1070-1090 grade, with a hardness rating of HRC 44-52 (Rockwell C). This hardness range ensures durability under pivot and retention duty without brittleness.
Q: Which Hyster models does the HY 91526 roll pin fit?
A: The HY 91526 is compatible with multiple Hyster electric lift truck models. Verify your specific model and assembly location to confirm this part number is correct for your equipment.
Q: What part numbers does the HY 91526 replace or cross-reference?
A: The HY 91526 replaces the older part number 302456 and cross-references to equivalent part number 66333 across different Hyster model lines and service bulletins.
Q: What is the surface finish on the HY 91526 roll pin?
A: The HY 91526 has an uncoated finish. The bare spring steel surface is exposed, so corrosion protection depends on the operating environment and any protective measures in the equipment assembly.
Q: Is the HY 91526 a direct replacement for part number 302456?
A: Yes. The HY 91526 supersedes and replaces the older Hyster part number 302456. Installation and retention function remain the same, making it a straightforward field replacement.
Q: How long does the HY 91526 roll pin typically last in service?
A: The HY 91526 is engineered for durability in mechanical pivot and retention applications. Service life depends on duty cycle intensity, load frequency, environmental exposure, and maintenance practices. Replace if bent, cracked, or worn.
