Frequently Asked Questions
Q: How does SU 9X5X5-SF-R-SIPED-A differ from the tire-only SU 9X5X5-SF-R-SIPED?
A: SU 9X5X5-SF-R-SIPED-A is a complete drive wheel assembly with the siped rubber tire pre-molded and secured to a cast steel hub. The tire-only version (SU 9X5X5-SF-R-SIPED) is just the rubber tire that requires pressing onto your existing hub. The assembly model is designed for direct bolt-on replacement, eliminating the need for a tire press. Choose the assembly when you need fastest replacement; choose the tire-only when preserving existing hubs.
Q: What is the hub bore diameter on SU 9X5X5-SF-R-SIPED-A, and does it fit standard electric pallet jack axles?
A: The SU 9X5X5-SF-R-SIPED-A assembly has a 5 inch bore (inner diameter) standard for Superior and equivalent electric pallet jack drive axles. Verify your axle shaft diameter is 1.5 inches or your specific mounting flange size. Most current Superior models use a 1.5 inch shaft; older units may vary. Before ordering, confirm your axle dimensions. Incorrect bore sizing prevents installation. If uncertain, check your jack serial number against the compatibility matrix or contact your parts supplier with the lift truck model number.
Q: Can I install SU 9X5X5-SF-R-SIPED-A without specialized tools?
A: Yes. The SU 9X5X5-SF-R-SIPED-A assembly is a plug-and-play replacement. Lift the truck, remove the two cotter pins or retaining rings holding the old wheel, slide the old assembly off the axle, slide the new assembly on, and secure with cotter pins. No tire press, no hub removal, no machining required. Total replacement time is 10 to 15 minutes per wheel. Recommended tools: socket wrench, cotter pin pliers, and jack stands for safety. Ensure the truck is safely elevated on jack stands before removing wheels.
Q: How do I know when SU 9X5X5-SF-R-SIPED-A assemblies need replacement?
A: Replace SU 9X5X5-SF-R-SIPED-A assemblies when: (1) siped tread depth becomes shallow or uneven, (2) truck experiences drive wheel slip or hesitation on level floor, (3) tire shows visible cracks or chunking, (4) bear wobbles or rotates erratically on the axle, or (5) rubber surface is hardened and no longer grips. Visual inspection every 500 operating hours is recommended. Compare to a new tire for tread visibility. If tread is half or less than new, schedule replacement.
Q: What is the weight rating per assembly on SU 9X5X5-SF-R-SIPED-A?
A: Each SU 9X5X5-SF-R-SIPED-A assembly is rated for approximately 2,600 to 2,800 lbs at 6 mph. Two assemblies on a drive axle share the load of a standard 5,000 to 6,000 lb pallet jack. Do not exceed the truck nameplate weight limit. Overloading reduces tire lifespan and causes premature wear, slip, and potential axle damage. Always verify the pallet jack load rating before placing loads beyond specified weight.
