Frequently Asked Questions
Q: What is the bore diameter and width of SU S294?
A: SU S294 is a standard-size load wheel. Typical dimensions are approximately 5-6 inches diameter with a 3-4 inch width, but exact specifications vary by supplier revision. Always measure your old wheel or consult the parts diagram for your specific truck model before ordering. Mismatch in bore or width will prevent proper installation or cause binding on the axle.
Q: Is SU S294 interchangeable with aftermarket wheels from other suppliers?
A: SU S294 may have equivalent parts from Crown, Raymond, or Jungheinrich under different SKUs, but do not assume interchangeability. Cross-reference the bore ID, width, and hub design. Some aftermarket wheels are slightly undersized, causing premature wear. Order only genuine or certified equivalent parts. When in doubt, contact the distributor with your truck serial number.
Q: How do I diagnose if SU S294 is worn or failing?
A: Check for flat spots or shine patterns on the rolling surface—this indicates uneven weight distribution or binding. Spin the wheel by hand; hard resistance or jerky motion means bearing seal failure or internal corrosion. Jack the truck and wiggle the wheel side-to-side; any movement indicates excessive bearing play. If you feel grinding vibration through the steering wheel, replace the wheel immediately.
Q: What torque specification should be used when installing SU S294?
A: Most load wheels are torqued to 15-20 ft-lbs on the axle pin or bolt. Check your truck manual for exact specification—over-torquing crushes the bearing seal, and under-torquing causes the wheel to slide. Use a calibrated torque wrench and tighten in a cross pattern if the wheel has multiple fasteners. After 50 operating hours, recheck torque to ensure it has not loosened.
Q: Can SU S294 be repaired or does it require full replacement?
A: SU S294 cannot be repaired if the bearing is bad or the polyurethane tread is cracked. The wheel is a sealed cartridge assembly and does not support bearing replacement in the field. If only the tread is worn flat but the bearing rolls freely, some facilities recoat with polyurethane epoxy as a temporary fix, but this extends life by only 1-2 months. Full replacement is recommended.
