Frequently Asked Questions
Q: What does SU S9112-XL-A include compared to SU S9112-XL?
A: SU S9112-XL-A is the complete assembly package for the XL wheel. It includes the larger SU S9112-XL wheel, bearing, mounting boss, and all fasteners and spacers needed for installation. SU S9112-XL is the wheel component only, so order SU S9112-XL-A if you need the full ready-to-install assembly.
Q: Is SU S9112-XL-A a complete plug-and-play assembly?
A: Yes, assuming your Superior jack frame accepts the XL-A mounting pattern. The assembly includes all internal components and hardware. You will not need additional fasteners or tools beyond standard wrenches. However, always verify your jack model compatibility before purchasing, as installation on incompatible frames can cause damage.
Q: Does SU S9112-XL-A fit on models that use standard SU S9112-A?
A: No. The XL-A assembly has a larger wheel diameter and may use different mounting geometry. Forced installation on a frame designed for SU S9112-A will cause misalignment, uneven wear, and accelerated failure. Always verify OEM compatibility before substituting assembly variants.
Q: What maintenance and replacement intervals apply to SU S9112-XL-A?
A: Inspect the assembly monthly for cracks, debris, and bolt tightness. The larger wheel diameter typically extends service life by 20 to 40 percent compared to standard assemblies under equivalent load conditions. Replace the assembly when visible wear exceeds 1/4 inch depth or when bearing play becomes audible during operation.
