Frequently Asked Questions
Q: What does the XL designation mean on the SU S151-XL wheel?
A: The XL designation indicates an extended or oversized variant of the base S151 design. The exact specifications differ from the standard S151, typically involving different bore diameter, width, or material composition. Always verify part numbers match your equipment requirements. Do not assume XL and standard versions are interchangeable.
Q: Can I replace a standard SU S151 with an SU S151-XL wheel without modifications?
A: Not necessarily. The bore diameter, hub width, or diameter may differ between the standard and XL versions. Before installing the S151-XL, measure your jack fork bore and hub width dimensions. If the bore diameter is larger on the XL, it will not fit a standard axle. Contact the manufacturer with your model number and existing wheel measurements to confirm compatibility.
Q: What tools do I need to install the SU S151-XL wheel?
A: You typically need a socket wrench set, bearing puller (for wheels on tapered axles), snap ring pliers if retaining rings are used, and a rubber mallet. Some installations require a wheel hub removal tool. Check your equipment manual for exact tool requirements and axle design. Do not force wheels on axles, as this damages bearings. Use proper pressing or tapping methods.
Q: What is the load capacity of the SU S151-XL?
A: The SU S151-XL is rated for the full capacity of the equipment on which it is installed, typically between 3,000 and 6,000 pounds for electric lift trucks. The XL design does not increase the jack load limit. Your equipment nameplate specifies the maximum safe load. Never exceed this limit regardless of wheel type.
Q: How often should I replace the SU S151-XL wheel?
A: Replace the SU S151-XL when you observe flat spots, cracks, uneven wear, or loss of steering control. Under typical warehouse duty, expect 12 to 24 months of service. High-speed operations, outdoor use, or rough concrete accelerates wear. Inspect wheels monthly. Record replacement dates to establish patterns for your operations and plan maintenance cycles.
