Frequently Asked Questions
Q: What does the SU S4001-A wheel assembly include, and how does it differ from ordering the SU S4001 wheel separately?
A: The SU S4001-A is a complete wheel assembly pre-mounted on a shaft or hub assembly with bearing hardware, ready for installation onto your lift equipment. The SU S4001 is the wheel only and requires you to have existing axle and bearing components. Order the SU S4001-A when replacing worn or damaged assemblies or when upgrading equipment. The wheel specifications are identical: 2.750 inch diameter x 2.000 inch width with 95A durometer poly material.
Q: What models and lift truck types is the SU S4001-A compatible with?
A: The SU S4001-A fits standard pallet jacks, hand trucks, walkie stackers, and low-profile lift equipment designed for 1.25 inch bore wheels. Verify compatibility by checking your equipment documentation for load wheel specifications or contacting your equipment manufacturer. The assembly dimensions are 2.75 inch OD x 2 inch width with a 1.4562 inch bore outside diameter. If your equipment manual does not reference this SKU, contact technical support before ordering to prevent installation issues.
Q: How do I install the SU S4001-A wheel assembly, and what tools are required?
A: Installation requires a basic socket set, adjustable wrench, and possibly a bearing puller if removing the old assembly. Raise and support the lift equipment safely on jack stands or blocks. Remove the cotter pin and axle nut from the existing wheel assembly. Use a bearing puller to remove the old assembly if necessary. Slide the SU S4001-A assembly onto the axle, align it with the equipment frame, and secure with the axle nut and cotter pin. Verify the wheel spins freely and check all fasteners for tightness before operating the equipment.
Q: What is the lifespan of the SU S4001-A wheel assembly, and how often should it be inspected?
A: The SU S4001-A assembly typically lasts 2 to 5 years depending on load capacity, frequency of use, and maintenance. Inspect the assembly monthly for worn or cracked wheel material, bearing noise, wobbling, or resistance when rotating by hand. If the bearing housing is leaking grease or the wheel does not spin freely, the assembly requires replacement. Replace the assembly immediately if you observe safety hazards such as flat spots, chunks missing from the wheel, or axle damage.
Q: Is the SU S4001-A assembly universal, or do I need to verify fitment before installation?
A: The SU S4001-A is not universal. You must verify that your lift equipment has a matching axle size, equipment frame geometry, and load wheel mounting configuration. Incompatible installation can result in misalignment, premature wear, or equipment failure. Check your equipment documentation, compare part numbers, or consult technical support before purchasing. Do not attempt to modify the assembly or equipment frame to force fitment, as this creates safety risks.
