LOAD WHEEL ASSEMBLY
Frequently Asked Questions
Q: What is the SU S9137-A load wheel assembly compatible with?
A: The SU S9137-A is a replacement load wheel assembly designed for electric lift trucks and pallet jacks. Verify your equipment model and serial range against Superior documentation before ordering to ensure proper fitment, as load wheel sizing varies by truck configuration.
Q: How do I identify if my load wheel needs replacement?
A: Replace the wheel if you observe flat spots, cracks, chunks missing from the tread, or if the wheel does not roll freely under light hand pressure. Worn tread reduces load capacity and increases bearing strain. Most wheels in high-duty cycle applications require replacement every 18 to 36 months depending on load and floor conditions.
Q: Is installation a plug-and-play replacement or does it require modification?
A: This is a direct bolt-on replacement. Remove the retaining hardware on the old wheel assembly, slide it off the axle shaft, and install the new SU S9137-A using the same fasteners. No machining or adapter plates are required. Ensure the bearing bore is clean before installation.
Q: What tools do I need to replace the SU S9137-A load wheel?
A: You will need an appropriately-sized wrench or socket set to remove the axle fasteners, a rubber mallet to gently tap the wheel assembly off the shaft if it is stuck, and a shop towel to clean the axle. Some technicians prefer a small bearing puller if the wheel does not slide off easily.
