Frequently Asked Questions
Q: Is the GWK-L50-LW a load wheel or steer wheel kit, and which fork position does it install in?
A: The GWK-L50-LW is a load wheel kit designed for the rear load roller (front) position on Lift-Rite and Big Joe L50 manual pallet jacks. The 3.00-inch diameter by 3.75-inch wide ultra-polyurethane wheels with 70D hardness are engineered to carry the pallet weight. Do not use this kit for the rear fork steer wheels, as the diameter and durometer rating are different.
Q: What is the difference between GWK-L50-LW and GWK-L50-LW-N, and which should I order?
A: The GWK-L50-LW features ultra-polyurethane 70D wheels with double sealed ball bearings and steel axles. The GWK-L50-LW-N is a nylon load wheel kit with zinc-plated hardware. Choose GWK-L50-LW if your original wheels were rubber or polyurethane compounds; choose GWK-L50-LW-N if you need nylon wheels for specific flooring applications (tile, vinyl) or reduced floor marking. Both kits fit the same L50 load roller position.
Q: How do I identify a worn GWK-L50-LW wheel that needs replacement?
A: Inspect for flat spots on the wheel edges where load has compressed the tread. Look for cracks, chunks, or delamination of the polyurethane from the steel core. If the jack pulls to one side under load or drifts when rolling empty, the wheels may be uneven or bearing spaced incorrectly. Spin each wheel by hand; smooth, free rotation is normal. Grinding or resistance indicates bearing wear and requires full kit replacement.
Q: Do I need to replace both GWK-L50-LW wheels at the same time, or can I replace one?
A: Replace both wheels on the same fork assembly at the same time. Mismatched wheel wear will cause the jack to pull sideways during operation, placing uneven stress on the axle and fork welds. If only one wheel shows damage, the mismatch in tread height and compliance will worsen load distribution and accelerate failure of the remaining wheel.
Q: What is the axle diameter on the GWK-L50-LW, and is it the same as on other L50 models?
A: The GWK-L50-LW is engineered for the standard 1.75-inch steel axle used on Lift-Rite L50 and Big Joe L50 models. If your jack has a different axle diameter, the wheel hub bore will not fit. Measure your existing axle or consult your jack documentation before ordering. The GWK-L504W-LW (four-way model) uses the same 1.75-inch axle but different wheel dimensions, so verify your exact jack configuration.
Q: How long do the double sealed ball bearings in the GWK-L50-LW last, and can they be regreased?
A: The double sealed ball bearings in the GWK-L50-LW are factory-sealed and rated for the service life of the wheel tread (typically 2 to 3 years in warehouse use). The seals are not serviceable; do not attempt to remove or repack the bearings, as this will damage the seal integrity and void any warranty. When the wheel needs replacement due to tread wear, replace the entire GWK-L50-LW assembly including bearings.
