Frequently Asked Questions
Q: What is included in the SU S9157-A load wheel assembly?
A: The SU S9157-A is a complete load wheel assembly that includes the polyurethane wheel (5.0 x 4.12 inches) with the bore and hub components pre-assembled. This eliminates the need to press or slide the wheel onto a separate axle. Verify that the assembly bore diameter (2.441 inches) fits your equipment axle before installation.
Q: What are the dimensional specifications for the SU S9157-A assembly?
A: The SU S9157-A has an outside diameter of 5.0 inches, width of 4.12 inches (127 x 104.65 millimeters), inside diameter of 2.125 inches, bore depth of 0.826 inches, and a bore outside diameter of 2.4406 inches. The tread profile features a 3/8 inch radius. These dimensions ensure compatibility with standard electric lift truck axles.
Q: Is the SU S9157-A a complete plug-and-play replacement?
A: The SU S9157-A is designed as a plug-and-play assembly replacement. Simply remove the retaining hardware from the existing wheel assembly and slide the SU S9157-A into position on the axle. Secure with the original retaining nut or clip. No pressing, adjustments, or tools are required beyond a wrench. Verify axle diameter compatibility before installation.
Q: How does the SU S9157-A compare to the standard SU S9157 wheel?
A: The SU S9157-A comes as a pre-assembled unit with the hub and wheel integrated, whereas the standard SU S9157 is a wheel core only. The -A designation indicates assembly form. Both use polyurethane tread and have identical bore specifications (2.441 inches). Choose the assembly (-A) if you need a complete replacement or the wheel core if your hub assembly is reusable.
Q: What maintenance is required for the SU S9157-A assembly?
A: Inspect the wheel regularly for tread wear, flat spots, or separation. Clean debris from the tread to maintain grip. Check the retaining hardware monthly to ensure it remains tight. In moderate duty, the SU S9157-A lasts 18-36 months. Replace the entire assembly if the tread is severely worn or if the bore or hub shows damage or play.
Q: Can the SU S9157-A assembly be repaired if the wheel becomes damaged?
A: The SU S9157-A is a sealed assembly unit and cannot be disassembled for repair in the field. If the wheel experiences tread separation, cracking, or large chunks missing, the entire assembly must be replaced. This design ensures safety and eliminates improvised repairs that could fail during operation.
