Frequently Asked Questions
Q: What equipment does the SU S9142-A Load Wheel Assembly fit?
A: The SU S9142-A is a load wheel assembly designed for electric lift trucks and pallet jacks. Verify the mounting bore diameter and axle type on your equipment before ordering. This is a complete wheel assembly, not just the wheel alone. Check your equipment documentation for the exact OEM part number to confirm compatibility.
Q: What is the difference between SU S9142-A, SU S9142-EZ, and SU S9142-XL?
A: All three are 4 x 2 poly load wheels with the same basic dimensions. The -EZ designation indicates a High Traction polyurethane compound designed for material handling equipment in wet floors and cold storage applications. The -XL designation provides enhanced load, cut, and tear resistance. Choose based on your operational environment: standard duty use (SU S9142-A), wet or cold storage (SU S9142-EZ), or heavy-duty demanding conditions (SU S9142-XL).
Q: Does SU S9142-A require special tools for installation?
A: Installation complexity depends on whether this is a press-fit assembly or bolt-on configuration. You will need the proper bearing puller tool if the wheel bearings must be removed from the old assembly. Verify the axle retention method on your specific pallet jack model. Consult the equipment manual or contact technical support with your model and serial range before attempting removal.
Q: What maintenance is required for the SU S9142-A assembly?
A: Inspect the wheel for flat spots, cracks, or uneven wear every 200 operating hours or monthly, whichever comes first. If the bearing assembly is sealed, no lubrication is required. If grease-packed, apply lightweight lithium grease annually or if bearing play becomes noticeable. Replace the entire assembly if the wheel separates from the core, bearings fail, or tread damage prevents safe operation.
Q: What is the load capacity for the SU S9142-A?
A: The SU S9142-A is rated for use on material handling equipment with standard duty cycles. Total load capacity depends on the number of wheels installed and the equipment design. A 4 x 2 wheel assembly typically handles 1000 to 1500 pounds per wheel in standard applications. Consult your equipment nameplate and the wheel specification sheet for exact ratings and never exceed the equipment manufacturer maximum load limit.
Q: Can SU S9142-A be cross-referenced to other OEM part numbers?
A: The SU S9142-A is a Superior brand part. To find cross-references, provide the complete OEM part number from your equipment and the equipment model and serial range. Equivalent assemblies exist from Crown, Toyota, Raymond, Yale, Hyster, and other lift truck manufacturers. Always verify wheel bore diameter, tread width, and bearing compatibility before substituting. Mismatched parts can cause handling problems and safety issues.
