Frequently Asked Questions
Q: What is the purpose of the BI 90820530 roll pin?
A: The BI 90820530 is a high-carbon spring steel roll pin that functions as a shear retention device for the hydraulic unit assembly on Bishamon BS-55 manual pallet jacks. It prevents the hydraulic unit from disconnecting or shifting under load.
Q: Which pallet jack models require the BI 90820530 roll pin?
A: The BI 90820530 is a direct OEM part for Bishamon BS-55 manual pallet jacks. Cross-references include 90820530 and BI90820530. Verify your equipment model matches BS-55 before ordering.
Q: What material is the BI 90820530 made from?
A: The BI 90820530 is manufactured from high-carbon spring steel with a plain finish coating. This material provides the spring tension and strength needed to reliably retain the hydraulic assembly under operating pressures and load conditions.
Q: What happens if the BI 90820530 roll pin fails or is missing?
A: A missing or failed BI 90820530 can allow the hydraulic unit to separate or shift, creating a safety hazard and loss of lifting function. The pallet jack cannot operate safely without this retention pin in place.
Q: How do I know if the BI 90820530 needs replacement?
A: Inspect the pin for corrosion, breakage, or loss of spring tension. If the hydraulic unit rocks or shifts side-to-side during operation, the roll pin may be compromised. A visual check during routine equipment maintenance identifies obvious damage.
