LOAD WHEEL ASSY, XL
Frequently Asked Questions
Q: What vehicles is the SU S9122-XL-A load wheel assembly compatible with?
A: The SU S9122-XL-A is an XL load wheel assembly designed for heavy-duty electric lift trucks and pallet jacks. Verify your truck model and serial range against the application chart, as XL wheels require reinforced axle brackets. Confirm mounting diameter and load rating before ordering to ensure proper fitment.
Q: How do I diagnose if the SU S9122-XL-A wheel assembly needs replacement?
A: Replace the assembly if you observe: wobbling or lateral play exceeding 1/8 inch when the wheel is rotated, flat spots or visible tread wear, bearing noise or squeaking that does not stop after cleaning, or the wheel does not roll freely under light hand pressure. A dragging sensation during operation also indicates bearing failure or wheel damage requiring replacement.
Q: What is the load capacity of the SU S9122-XL-A assembly?
A: Load capacity depends on the truck configuration and axle design. The XL designation indicates increased diameter and width for higher load distribution. Refer to the vehicle nameplate or specification sheet for maximum load per wheel. Exceeding rated capacity causes premature bearing wear and wheel damage.
Q: Is installation of the SU S9122-XL-A a plug-and-play replacement?
A: Installation requires removing the axle pin or bolt, sliding off the old assembly, and installing the new one. No modifications are needed if you are replacing an identical original assembly. If upgrading from standard to XL, verify bracket compatibility first. Use appropriate hand tools and secure the axle pin firmly to prevent wheel separation during operation.
Q: How often should the SU S9122-XL-A wheel assembly be maintained?
A: Inspect monthly for bearing play, tread wear, and debris accumulation. Clean wheels weekly if operating in wet or dirty environments. Bearings do not require lubrication on sealed units. Replace the entire assembly when bearings fail or tread depth falls below 1/16 inch. Expected lifespan is 2 to 5 years depending on duty cycle and load.
