Frequently Asked Questions
Q: What is the SU S9631-A and what jack models does it fit?
A: The SU S9631-A is a polyurethane load wheel assembly designed for electric lift trucks and pallet jacks. It is the manufacturer designation for the same product marketed as OEM part number SU S9631. Always verify your jacks model and serial number against your equipment documentation to confirm fitment.
Q: Is SU S9631-A compatible with both manual and electric pallet jacks?
A: The SU S9631-A is engineered for electric lift truck and powered pallet jack applications. Manual (hand) pallet jacks typically use different wheel profiles and dimensions. Do not assume cross-compatibility. Confirm your jacks specifications and required wheel dimensions before ordering.
Q: What is the wheel bore size and axle compatibility for SU S9631-A?
A: The SU S9631-A features a sealed ball bearing with a standard bore diameter compatible with most electric truck axles. Contact our parts team with your jack model and serial number to confirm exact axle diameter and mounting requirements. Mismatched bore sizes will prevent proper installation.
Q: What is the expected lifespan of the SU S9631-A wheel?
A: The SU S9631-A polyurethane tread typically lasts 12 to 24 months depending on floor type, load cycles per day, and environmental conditions. Smooth concrete extends life; rough or oily floors accelerate wear. Monitor tread depth and replace when wear reaches 50 percent of original thickness or when bearing damage appears.
Q: Can you repair the SU S9631-A or must it be replaced as a complete assembly?
A: The SU S9631-A is a sealed assembly and cannot be repaired. If the polyurethane tread is damaged, the bearing is worn, or the steel core is bent, you must replace the entire wheel assembly. Attempting to reglue or patch the tread compromises safety and load stability.
Q: What tools do I need to replace the SU S9631-A?
A: You typically need a socket wrench or adjustable wrench to remove the axle fastener (bolt or cotter pin), a shop rag to clean the axle, and a new lock pin or fastener if the old one is bent or damaged. Ensure the jack is on a level surface and secured to prevent movement during wheel replacement.
