Frequently Asked Questions
Q: How does the SU S635-A assembly differ from the SU S635 single wheel?
A: The SU S635-A is a complete assembly that includes the wheel, sealed bearing, axle bracket, and mounting hardware. The SU S635 is the wheel only. Order the SU S635-A if you need a drop-in replacement assembly or if bearings are damaged.
Q: What tools and skills are required to install the SU S635-A Load Wheel Assembly?
A: Installation requires basic mechanical skills, a socket wrench set, and a torque wrench. Remove the axle pin, slide off the old assembly, position the new SU S635-A, and torque bolts to 35 foot-pounds. No frame modification is necessary. Installation time is typically 10-15 minutes per side.
Q: Can the SU S635-A be retrofitted to older Yale or Hyster models?
A: The SU S635-A fits Yale forklifts series GLC040-080 and Hyster models E25-E35 with original 1.625-inch axle bore. Check the axle diameter and truck serial number before ordering. Some serial ranges require axle sleeve adapters not included with the assembly.
Q: What is the warranty and expected service life of the SU S635-A?
A: The SU S635-A carries a 12-month parts warranty from the date of shipment. Expected service life is 4-6 years under typical warehouse conditions with normal maintenance. Sealed bearings do not require greasing but should be inspected annually for cracks or corrosion.
Q: What symptoms indicate the SU S635-A needs replacement?
A: Replace the assembly if you notice grinding noise from the wheel, lateral play greater than 1/8 inch at the rim, polyurethane chunks missing from the tread, or the truck pulling to one side during operation. These symptoms indicate bearing failure or wheel degradation.
