Frequently Asked Questions
Q: What does the XL designation mean on the SU S487-XL wheel?
A: XL indicates this is a heavy-duty or extended load variant, though the SU S487-XL maintains identical physical dimensions to SU S487 and SU S487-A. The XL designation may indicate enhanced bearing or cast core specifications. Refer to your truck specifications to confirm if your application requires XL-rated wheels. SU S487-XL is interchangeable with SU S487 and SU S487-A.
Q: What are the dimensional specifications of the SU S487-XL?
A: The SU S487-XL has an outside diameter of 8.000 inches (203.20 mm) and width of 2.500 inches (63.50 mm). Bore inside diameter is 1.938 inches. Bore outside diameter is 2.0467 inches. Bore depth is 0.785 inches. Hub width is 2.5 inches. These match SU S487 and SU S487-A specifications for direct compatibility.
Q: Can I replace only one SU S487-XL wheel if the others are older SU S487 wheels?
A: Technically yes, because dimensions are identical. However, best practice is to replace wheels in matched sets (all four load wheels at once) to ensure even wear characteristics and consistent handling. If one wheel is significantly worn and others are new, the truck will not roll evenly. Replace in pairs at minimum.
Q: What is the proper procedure to install an SU S487-XL wheel onto a lift truck axle?
A: Clean the axle thoroughly. Align the wheel bore with the axle. If bolted on, insert bolts and tighten in crosshatch pattern (alternating opposite sides) to ensure even seating. If press-fit, use a bearing press or wheel installation tool. Do not force the wheel by hammering. After installation, spin the wheel freely by hand and verify no wobble. Test run the truck and listen for grinding sounds.
Q: How should I diagnose if an SU S487-XL wheel has a bent or damaged bore?
A: A bent bore will cause the wheel to wobble or rub against the truck frame when the truck is in operation. Remove the wheel and place it on a flat surface. Roll the wheel and observe if it tracks straight or wobbles. Measure the bore opening with calipers to verify it matches 2.0467 inches OD specification. If the bore is out of round or the wheel does not roll true, the core is damaged and must be replaced.
