Load Wheel Assembly
Frequently Asked Questions
Q: What applications is the SU S934-A Load Wheel Assembly designed for?
A: The SU S934-A is a load wheel assembly used in electric lift trucks and material handling equipment. It handles transverse loads in the wheel path and is typically mounted on the drive axle or steering axle of pallet jacks and electric hand trucks. It supports the full load capacity of the vehicle.
Q: Can the SU S934-A be cross-referenced to OEM part numbers from Crown, Yale, or Raymond?
A: Yes. The SU S934-A is a replacement for equivalent load wheel assemblies used across Crown, Yale, Raymond, and Hyster electric lift trucks. Always verify the wheel diameter, bearing size, and mounting plate dimensions match your specific jack model before ordering. Cross-reference your OEM part number with our technical team if you need confirmation.
Q: What tools and steps are required to install the SU S934-A?
A: Installation requires wheel removal from the axle, which typically involves a socket set, bearing pullers, and bearing presses. The assembly is press-fit onto the axle shaft. Do not attempt installation without a bearing press. Improper installation can damage bearings and seals, leading to premature failure and safety hazards. Lift the truck on a jack stand before removing wheels.
Q: How do I diagnose a failing load wheel assembly?
A: Signs of a failing SU S934-A include grinding or squealing noise from the wheel path, roughness or play when spinning the wheel by hand, and uneven tire wear. Lift the truck and manually spin each wheel. Excessive resistance, noise, or wobble indicates bearing failure or seal damage. Stop use immediately to prevent loss of control.
Q: What is the typical lifespan of the SU S934-A and when should it be replaced?
A: Under normal use in warehouse environments, the SU S934-A typically provides 2 to 4 years of service, depending on load cycles and floor conditions. High-traffic or cold storage applications may reduce lifespan to 18 to 24 months. Replace immediately if bearings show play, if noise develops, or if the assembly cannot be cleaned and repacked effectively.
Q: Does the SU S934-A require regular maintenance or repacking?
A: Yes. If the assembly is sealed grease-packed, inspect seals annually for cracks or leakage. Many load wheel assemblies are rebuildable. If grease leaks or seals fail, the assembly can be removed, cleaned, inspected, and repacked with new seals and grease. This extends service life by 12 to 18 months compared to replacement.
