Frequently Asked Questions
Q: What BT Prime Mover models use the GWK-PMX-LW load wheel kit?
A: The GWK-PMX-LW is engineered specifically for BT Prime Mover PMX electric pallet jacks. This kit is not compatible with other BT models or Prime Mover product lines. Always verify your jack is a PMX model before ordering. Confirm the part number on your jack documentation to avoid purchasing an incompatible kit.
Q: What polyurethane hardness and material composition does the GWK-PMX-LW specify?
A: The GWK-PMX-LW uses bonded polyurethane tread on a steel core with Shore A95 durometer hardness. The bonded construction prevents tread separation under heavy loads and continuous operation. The 95A rating balances wear resistance with ride comfort on hard warehouse floors. The machined surface, plain finish provides consistent rolling contact.
Q: Is the GWK-PMX-LW a complete kit or wheel-only?
A: The GWK-PMX-LW is a complete kit that includes bonded polyurethane wheels, precision ball bearings, axles, and fasteners. All components needed for load wheel replacement are included. You do not need to source bearings or hardware separately. Installation requires standard socket and wrench tools plus a bearing puller if the bearing is press-fit.
Q: How do I diagnose worn load wheels on a BT PMX electric pallet jack?
A: Replace wheels if you observe flat spots, visible cracks in the tread, chunks of polyurethane missing, or excessive vibration during forward travel. Spin the wheel by hand to check for bearing noise or rough rotation. If wheels are worn 3/8 inch or more below their original diameter, they have lost load capacity. Worn wheels reduce truck speed and increase motor strain on the hydraulic system.
Q: What tools and safety precautions do I need to install the GWK-PMX-LW?
A: Use a socket set, crescent wrench, and possibly a bearing puller to remove press-fit bearings. Ensure the jack is fully lowered and stable before working underneath. Do not work under a raised load. Do not apply heat to remove bearings. Follow the PMX service manual for torque specifications on fasteners. Improper assembly causes bearing failure and safety hazards.
Q: What maintenance schedule should I follow for the GWK-PMX-LW kit?
A: Inspect load wheels monthly for wear, damage, and bearing play. Clean wheels regularly to remove floor debris and oils that degrade polyurethane. In heavy-duty warehouse use, expect load wheel replacement every 2 to 4 years depending on cycle rates and floor condition. Bonded polyurethane wheels are designed for continuous duty, but tread separation requires immediate replacement. Do not attempt to re-surface bonded wheels.
