Frequently Asked Questions
Q: What is the MO 609 roll pin and what does it secure?
A: The MO 609 is an OEM slotted spring pin designed for Mobile manual pallet jack chassis and subassembly applications. It functions as a press-fit retention pin for pivot points and articulation linkages where precise alignment and secure retention are required.
Q: What are the dimensions and specifications of the MO 609?
A: The MO 609 roll pin is 1.18 inches in length with a nominal diameter of 0.20 inches. It is manufactured from oil-hardened spring steel in a plain, uncoated finish. The pin meets DIN EN ISO 8752 specifications for spring pin construction and performance.
Q: Which Mobile pallet jack models use the MO 609 roll pin?
A: The MO 609 is designed for Mobile manual pallet jack models, with cross-reference to ML55 equipment. This spring pin is a standard component in Mobile frame assemblies. Confirm your pallet jack model matches before ordering.
Q: Why is the MO 609 made from oil-hardened spring steel?
A: Oil-hardened spring steel provides the MO 609 with elasticity and strength required for secure press-fit retention. The material resists shear forces from load cycles and maintains dimensional stability over time. Spring hardness prevents the pin from backing out or loosening during equipment use.
Q: Can the MO 609 be reused if removed?
A: Spring pins like the MO 609 lose elasticity and retention force after removal. Best practice is to replace the pin with a new one during reassembly. Reusing a worn spring pin can result in inadequate retention and potential component failure during operation.
Q: What problems occur if the MO 609 pin fails or backs out?
A: A missing or failed MO 609 pin can cause chassis misalignment, frame play, loss of pivot stability, and component separation during lift cycles. This results in unsafe equipment operation, damage to frame assemblies, and potential load handling failures. Replace immediately if the pin is missing or loose.
