Frequently Asked Questions
Q: What are the key differences between SU 9631-A and other load wheel models?
A: The SU 9631-A is a load wheel assembly variant. The -A designation typically indicates an assembly with bearing and hub pre-mounted and pre-aligned. Compare the diameter and tread width to your current wheel to verify compatibility. Do not assume all load wheels are interchangeable across electric lift truck brands and models.
Q: Is the SU 9631-A sealed and how should it be maintained?
A: Most load wheel bearings are sealed or shielded to prevent water and debris ingress. Do not attempt to clean, repack, or disassemble the bearing. Wipe the wheel tread clean as needed. If water leaks from the bearing or the wheel makes grinding noise, replace the assembly immediately.
Q: What torque specification should be used when installing the SU 9631-A wheel?
A: Check your truck service manual for the correct axle bolt torque. Typical range is 35 to 75 foot-pounds depending on axle diameter and bolt grade. Over-tightening can crush the bearing preload and cause premature failure. Under-tightening causes the wheel to shift and creates noise and wear.
Q: Can the SU 9631-A bearing be replaced separately or must the entire wheel be discarded?
A: Bearing replacement on the SU 9631-A assembly is not recommended in field service. The bearing is pressed and sealed as a unit. Attempting to remove and install a new bearing risks damaging the hub or bore. Always replace the complete wheel assembly for reliability and warranty coverage.
