Frequently Asked Questions
Q: What material is the PR 20686 roll pin made from and what are its specifications?
A: PR 20686 is manufactured from high-carbon spring steel (SAE 1070-1095) per ASME B18.8.2 standards with Rockwell hardness rating C44-C50. This material composition provides the spring tension and wear resistance needed for shaft retention in drive assemblies.
Q: Which equipment models use PR 20686 and what are the cross-reference part numbers?
A: PR 20686 is an OEM replacement for Prime Mover electric lift trucks. Cross-reference part numbers include PM20686, PM 20686, and TSA/PMP 110373-33. Use these numbers when searching for equivalent inventory or OEM documentation.
Q: What is the function of a roll pin in a pallet jack drive assembly?
A: The roll pin provides secure press-fit retention of shafts within the drive assembly. It prevents shaft rotation or axial movement under load, maintaining proper engagement between motor and transmission components.
Q: How do I identify if a PR 20686 roll pin needs replacement?
A: Replace the roll pin if you observe shaft slippage, excessive play in the drive assembly, or visible deformation. A worn or failed pin will cause inconsistent drive performance or complete loss of power transmission.
