Frequently Asked Questions
Q: What are the dimensions and specifications of the SU 9151-XL load wheel assembly?
A: The SU 9151-XL features a 5.00 inch diameter by 4.125 inch width polyurethane tread bonded to a cast iron core. The load wheel hardness is 97A durometer. It uses precision sealed bearings and SAE Grade 8 axle fasteners. The wheel has a maximum load rating of 5000 lbs and includes proprietary XL3 bonding technology with a machined core and anti-corrosive coating.
Q: Which electric lift truck models is the SU 9151-XL compatible with?
A: The SU 9151-XL is compatible with Crown, Toyota, Raymond, Yale, Hyster, Jungheinrich, Linde, Clark, Mitsubishi, CAT, and BT electric lift trucks. Cross-reference part numbers include S9151-XL-A. Verify your equipment model and wheel mounting specifications before ordering.
Q: What material is the tread made from and why does that matter?
A: The SU 9151-XL uses polyurethane tread bonded to a cast iron core. Polyurethane provides excellent wear resistance, load capacity, and floor protection compared to rubber or solid steel wheels. The 97A durometer rating indicates a harder compound suitable for general indoor material handling applications.
Q: What is the XL3 bonding technology and does it affect replacement?
A: XL3 is a proprietary bonding technology that bonds the polyurethane tread to the cast iron core. This technology enhances durability and prevents tread separation during normal operation. When replacing this wheel, the SU 9151-XL is the correct direct replacement assembly; the bonding technology is integrated during manufacturing.
Q: How do I know when the SU 9151-XL needs replacement?
A: Replace the wheel when tread wear exceeds 1/8 inch, visible cracks or flat spots appear on the tread, or the wheel does not spin freely due to bearing wear. Sealed bearings are maintenance-free but cannot be relubricated once installed. If bearing noise develops, the entire assembly must be replaced.
Q: What fasteners and hardware are required to install the SU 9151-XL?
A: The SU 9151-XL uses SAE Grade 8 axle fasteners. When replacing, reuse the existing Grade 8 axle bolt and nut from your equipment if they are undamaged. Do not substitute with lower-grade fasteners. Tighten fasteners securely but do not overtighten, as this can damage the sealed bearings. Verify axle diameter and length match your equipment before installation.
