Frequently Asked Questions
Q: What does XL designation mean on the SU S9141 XL wheel?
A: The XL designation indicates an extended-life or upgraded version compared to the base S9141. It features precision-finished machined steel core construction for improved durability and load distribution in electric lift truck applications.
Q: What are the cross-reference part numbers for SU S9141 XL?
A: The SU S9141 XL is cross-referenced as SU9141-XL, SU9141XL, and 9141XL. Always verify the exact part number on your equipment nameplate before ordering, as similar-looking part numbers may not be identical.
Q: How does SU S9141 XL compare to standard SU S9141 in terms of load capacity?
A: Both wheels share the same nominal 3.25 inch by 6.5 inch dimensions. Load capacity is determined by the equipment model and axle assembly, not the wheel alone. The XL variant offers enhanced core rigidity and precision finishing for extended service life under equivalent loads.
Q: Can I retrofit SU S9141 XL wheels onto equipment originally fitted with standard S9141 wheels?
A: Retrofitting is possible if the bore diameter, bore depth, axle fastening system, and hub width match exactly. Measure your existing wheel bore specifications and consult your equipment manual or OEM parts diagram to confirm fit. Incorrect bore size will cause wobbling or not mount at all.
Q: What maintenance is required for the SU S9141 XL wheel assembly?
A: Inspect bearings periodically for play or grinding noise. Verify fasteners remain tight. Clean polyurethane tread regularly to remove debris. Lubricate bearings according to your equipment manual interval, typically every 250 to 500 operating hours or quarterly.
