Frequently Asked Questions
Q: What is the difference between SU S376-A and SU S376-XL?
A: Both are 5 x 3 Cushothane load wheels with identical core specs: 5.000 inch OD, 3.000 inch width, 2.625 inch ID, and 2.8341 inch bore OD. The -XL designation indicates extra load capacity or hub design for heavy-duty applications. Always verify your jack model and load rating before substituting one for the other.
Q: Will SU S376-A fit my pallet jack if I currently have a different 5 x 3 wheel brand?
A: SU S376-A will fit if the existing wheel has a 2.8341 inch bore OD, 2.625 inch ID, and 0.739 inch bore depth. Common equivalents include Yale, Crown, and Hyster OEM wheels with these exact dimensions. Measure your current wheel bore and hub width before ordering. Mismatched bore sizes will cause wobbling and premature bearing wear.
Q: How do I know if my SU S376-A load wheel needs replacement?
A: Replace the wheel if you observe: flat spots or chunks missing from the Cushothane surface, audible grinding or squealing during use, visible wheel wobble side-to-side, uneven wear patterns, or diameter loss exceeding 0.25 inch. Cushothane wheels typically last 3-5 years with regular use depending on load and floor conditions. Check the wheel before each shift by spinning it by hand and listening for bearing noise.
Q: What tools and steps do I need to replace an SU S376-A wheel?
A: Remove the wheel by: (1) lifting the jack frame on blocks to unload weight from the wheel, (2) removing the cotter pin and axle nut, (3) sliding the old wheel off the axle. Install the new SU S376-A by: (1) aligning the bore with the axle, (2) sliding the wheel onto the axle fully, (3) reinstalling the axle nut hand-tight then torquing to 25-35 ft-lbs, (4) inserting a new cotter pin. Do not over-tighten or the wheel will bind and overheat.
Q: What load capacity does the SU S376-A wheel support?
A: SU S376-A load wheels are rated for the combined load capacity of your jack model. The wheel itself handles approximately 2,500 to 3,500 lbs per wheel depending on bearing size and hub material. Do not exceed your jacks rated load limit. Overloading causes bearing failure, axle bending, and permanent wheel damage. Refer to your jacks nameplate for total capacity.
Q: How do I maintain SU S376-A wheels to extend lifespan?
A: Monthly: inspect for debris, cracks, and flat spots; spin each wheel by hand and listen for grinding. Quarterly: wipe wheels clean and check that bearings spin freely without noise or play. Annually: lubricate wheel bearings if grease fittings are present using a general-purpose wheel bearing grease. Avoid operating on splintered or debris-covered floors. Store the jack indoors when not in use to prevent Cushothane degradation from UV and temperature extremes.
