Frequently Asked Questions
Q: Is SU 9139-A compatible with Crown GPW Series pallet trucks?
A: Yes. SU 9139-A is engineered as a direct replacement load wheel for Crown GPW Series electric pallet trucks. Cross-reference part numbers GW 9139-A and SU 9139-EZ-A are equivalent. Verify your truck model uses standard GPW load wheel mounting before ordering.
Q: What material is the wheel tread and core on SU 9139-A?
A: SU 9139-A features a machined steel core with bonded maroon polyurethane tread. The polyurethane provides grip and wear resistance in industrial environments. Sealed bearings are pre-installed.
Q: How do I diagnose if SU 9139-A needs replacement?
A: Replace the wheel if you observe: flat spots or chunks missing from the tread, squealing or grinding sounds from the bearing, visible cracks in the polyurethane, or reduced traction on smooth floors. Jack should not wobble or pull to one side during operation.
Q: What tools and steps are required to install SU 9139-A?
A: Installation requires an adjustable wrench or hex key sized to your truck model, typically 5mm to 8mm. Raise the truck fully. Remove the retaining cotter pin or clip from the axle, slide off the old wheel, and slide the new SU 9139-A onto the axle shaft. Reinstall the cotter pin or clip and lower the truck. Verify the wheel spins freely with no binding.
Q: What is the recommended maintenance interval for SU 9139-A?
A: Inspect the wheel monthly for tread wear and bearing noise. Bearings are sealed and cannot be relubricated. Under normal industrial use, expect 2 to 4 years of service life depending on floor type and load frequency. Replace immediately if tread wear reaches 50 percent or bearing noise develops.
