Frequently Asked Questions
Q: What is the SU 9138-A load wheel assembly and what specifications are available?
A: The SU 9138-A Load Wheel Assembly is a mechanical load wheel component for electric lift trucks. Manufacturer Part Number: SU 9138-A. Limited technical specification data is documented in available sources, including material grade, surface finish, and rated load capacity. Contact the supplier or consult your lift truck manual to obtain complete dimensional and material specifications before ordering.
Q: How do I determine if the SU 9138-A is compatible with my electric lift truck?
A: Verify the OEM or manufacturer part number from your existing wheel or consult your lift truck manual. Cross-reference against the SU 9138-A part number to confirm compatibility. No cross-reference, OEM equivalent, or alternative part numbers are documented for the SU 9138-A. If you are unsure, measure your existing wheel diameter, tread width, and bore size, then provide those specifications to the parts supplier to confirm fitment.
Q: What material and surface treatment is the SU 9138-A made from?
A: Material grade and surface finish specifications are not specified in available sources for the SU 9138-A. The part is a load wheel assembly, which typically consists of a polyurethane tread bonded to a steel core with an integrated bearing pocket or bore. Request detailed material and surface finish documentation from the parts supplier before ordering to ensure the wheel meets your application requirements.
Q: What is the rated load capacity of the SU 9138-A?
A: The rated load capacity is not specified in available sources for the SU 9138-A. Load capacity is typically inherited from your electric lift truck rating rather than the wheel alone. Consult your truck manual or nameplate to determine the truck load capacity. Do not exceed the truck manufacturer maximum load rating, as overloading damages wheels, bearings, and the truck frame.
Q: How do I install the SU 9138-A load wheel?
A: Raise the truck safely on a level work surface. Remove the axle fastener or pin. Slide the old wheel off the axle journal. Inspect the axle and bearing for damage. Slide the SU 9138-A wheel onto the axle, aligning the bore with the journal. Reinstall the axle fastener and secure per the truck manufacturer specifications. Spin the wheel by hand to verify smooth rotation. Lower the truck and test operation before placing the truck in service.
Q: What should I do if the SU 9138-A arrives and does not fit my truck?
A: Do not force the wheel onto the axle. Stop and verify the bore diameter and axle journal diameter match. Measure your existing wheel and compare dimensions to the SU 9138-A specification. If dimensions do not match, contact the parts supplier immediately to confirm the correct part number for your lift truck model. Forcing an incorrect bore size damages the axle and bearing, resulting in costly repairs.
