Frequently Asked Questions
Q: Is SU 9131-A equivalent to SU 9131-XL?
A: Yes. SU 9131-A is a direct equivalent to SU 9131-XL. Both are 8 inch by 4 inch polyurethane load wheel assemblies with the same 97A durometer Cushothane XL compound and XL3 chemical bond. You can use cross-reference numbers SU9131XL, 9131XL, and SUS9131-XL-A interchangeably. Verify your equipment compatibility before ordering.
Q: What equipment is the SU 9131-A compatible with?
A: The SU 9131-A 8x4 load wheel is engineered for Crown RR5200 series electric pallet jacks, including the RR5225-45 model. It is a mid-duty class wheel suitable for standard warehouse and material-handling applications. Always verify the mounting pattern and axle diameter on your specific equipment before purchase to ensure proper fitment.
Q: What are the specifications of the SU 9131-A?
A: Specifications: Outside diameter is 8.000 inches (203.20 mm). Width is 4.000 inches (101.60 mm). Material is polyurethane with 97A durometer hardness, providing good grip and cut-tear resistance. The wheel features an XL3 chemical bond between the polyurethane tread and steel core for durability under heavy cycling.
Q: How do I know when to replace the SU 9131-A load wheel?
A: Replace the SU 9131-A when the tread is worn flat, visibly cracked, or chunked. If the wheel does not spin smoothly or makes grinding sounds, the bearings are likely damaged. Excessive wobble when rotated by hand, or visible flat spotting indicates replacement is needed. Most polyurethane wheels last 2 to 4 years in active duty service.
Q: How do I install the SU 9131-A on my Crown pallet jack?
A: Installation steps: (1) Raise the truck on jack stands and secure it. (2) Remove the cotter pin and axle bolt. (3) Slide the old wheel off the axle. (4) Position the SU 9131-A onto the axle, aligning the bearing races with the axle bore. (5) Install the axle bolt and tighten hand-tight, then add the cotter pin. (6) Spin the wheel to confirm free rotation. Do not over-tighten, which damages the precision bearings.
