LOAD WHEEL
Frequently Asked Questions
Q: What load capacity does the SU S553 load wheel support?
A: The SU S553 supports standard electric lift truck loads up to 3000 lbs per wheel depending on truck configuration. Check your truck manual for exact capacity. Exceeding rated load causes premature bearing wear and wheel failure.
Q: Is the SU S553 compatible with my electric lift truck model?
A: SU S553 fits most standard 4-wheel electric lift trucks with 3-inch bolt patterns and 6-inch wheel diameter. Verify your truck documentation before ordering. If your truck uses a 5-inch or 8-inch diameter wheel, you need a different SKU.
Q: How do I diagnose if my SU S553 wheel needs replacement?
A: Replace the wheel if you see flat spots, cracks, or excessive wear on the tire surface; if the wheel pulls to one side during operation; or if bearing noise increases during use. Test by spinning the wheel by hand - it should rotate freely without grinding sounds.
Q: What is the installation process for the SU S553?
A: Lift the truck on jack stands, remove the four bolts holding the old wheel, slide off the assembly, align the new SU S553 wheel with the axle, insert bolts, and torque to 45 foot-pounds in a cross pattern. Do not over-torque or the wheel may crack.
Q: What maintenance is required for the SU S553 wheel?
A: Inspect wheels monthly for damage, cracks, or flat spots. Clean wheels every 3 months to prevent debris buildup. If wheels begin to squeak or bind, bearing grease may be depleted - service or replace bearings immediately. Expected lifespan is 2-3 years with normal use.
Q: Can I use the SU S553 as a direct replacement for my old wheel?
A: Yes, the SU S553 is a direct bolt-on replacement for OEM wheels on compatible trucks. However, verify bolt pattern and wheel diameter match your truck first. Do not mix wheel types on the same truck - all four wheels should be the same model.
