LOAD WHEEL
Frequently Asked Questions
Q: What is the load rating for SU S338 load wheels?
A: SU S338 load wheels are rated for 2500 lbs per wheel in standard electric lift truck applications. Verify your truck model and serial range to confirm compatibility, as some older models may use a reduced load capacity.
Q: Is SU S338 equivalent to any other brand load wheel?
A: SU S338 is equivalent to Yale EL-25 and Hyster H25 load wheels. All three use the same 1.5 inch bore diameter and hub spacing. Always verify the bolt pattern on your existing wheel before ordering a cross-brand replacement.
Q: Can I replace SU S338 with SU S339 on my truck?
A: No. SU S338 and SU S339 have different hub diameters and load ratings. SU S338 is a standard steel wheel; SU S339 is a lighter-duty alternative wheel. Mixing them on the same axle will cause uneven load distribution and may damage the steering linkage.
Q: How do I diagnose a worn SU S338 load wheel?
A: Signs of wear include flat spots on the rubber tread, play or wobbling when you lift the truck and spin the wheel by hand, and uneven tire wear patterns. If the wheel rattles on the axle or the truck pulls to one side, the wheel bearing or hub may be damaged and the entire wheel assembly should be replaced.
Q: What tools do I need to replace SU S338 load wheels?
A: You will need a 3/4 inch socket, jack, jack stands, and a torque wrench. The hub bolts must be torqued to 65 ft-lbs in a star pattern. Do not exceed this torque or you risk stripping the bolt threads and damaging the wheel hub casting.
Q: What is the typical lifespan of an SU S338 load wheel?
A: Under normal warehouse operation (40-50 hours per week on level floors), an SU S338 load wheel lasts 3-5 years. High-temperature environments or outdoor use will reduce lifespan to 2-3 years. Grease the wheel bearing every 6 months to extend life.
