Frequently Asked Questions
Q: What is the difference between the SU S9141-XL-A and the SU S9141-XL?
A: The SU S9141-XL-A is a complete assembly variant, while the SU S9141-XL is the wheel core only. The -A designation indicates the wheel arrives as a finished, bolt-on assembly with bearings and hub ready for immediate installation. Both use identical Cushothane XL polyurethane compound and 97A Shore hardness. Choose the -A version if you need a plug-and-play replacement.
Q: What are the exact dimensions of the SU S9141-XL-A assembly?
A: The SU S9141-XL-A measures 3.250 inches outer diameter by 6.500 inches tread width. The bearing bore is 25mm (0.984 inch). Outside bore diameter is 2.0467 inches with a 1.938-inch ID. Hub width is 6.500 inches. Internal bore depth and shoulder dimensions match standard 25mm bearing specifications.
Q: Which OEM pallet jacks accept the SU S9141-XL-A assembly?
A: The SU S9141-XL-A is a heavy-duty load wheel assembly for electric and manual pallet jacks from Crown, Toyota, Raymond, Yale, and Hyster that use 25mm bore load wheel assemblies in 3.25-inch diameter by 6.5-inch width configuration. Cross-reference your equipment serial range and model number against the load wheel assembly specification. No formal OEM cross-reference is published.
Q: How do I install the SU S9141-XL-A assembly on my pallet jack?
A: Remove the jack from service and lower the mast fully. Unbolt the axle assembly or axle pin holding the old wheel. Slide the SU S9141-XL-A assembly onto the axle shaft, aligning the bore. Verify the assembly seats fully and rotates without resistance or grinding noise. Reinstall and torque all fasteners per your truck manual. Test rotation before operating under load.
Q: What bearing type does the SU S9141-XL-A use?
A: The SU S9141-XL-A accommodates standard 25mm bore ball bearings. Sealed or shielded bearing designs are common for warehouse duty to reduce contamination. If bearings require replacement, use 25mm ID x 52mm OD x 15mm width deep-groove ball bearings or equivalent sealed specification. Do not substitute sealed bearings with open bearings without re-greasing intervals.
Q: What is the expected service life of the SU S9141-XL-A assembly?
A: The SU S9141-XL-A assembly typically lasts 24 to 36 months in heavy-cycle warehouse duty. XL polyurethane and 97A Shore hardness provide extended wear life. Bearing life depends on lubrication and load conditions. Inspect quarterly for tread wear depth, cracks, bearing noise, or hub-to-polyurethane separation. Replace the entire assembly if the hub delaminates.
