Frequently Asked Questions
Q: Is the GWK-L504W-LW compatible with standard four-way pallet jacks, or only Lift-Rite L50 4 Way models?
A: The GWK-L504W-LW is engineered specifically for Lift-Rite L50 4 Way and Big Joe L504Way models. Four-way jacks differ from two-way jacks in fork width, lifting mechanism clearance, and wheel mounting geometry. Do not assume the GWK-L504W-LW will fit other four-way brands or models. Confirm your jack model matches the L50 4 Way or L504Way designation before ordering, as wheel kits are not cross-compatible across four-way platforms.
Q: What is the wheel diameter and material of the GWK-L504W-LW, and how does it compare to the standard L50 kit?
A: The GWK-L504W-LW features carbon steel 1.75-inch diameter wheels with sealed ball bearings, pre-assembled on axles. This differs from the standard L50 kit (GWK-L50-LW), which uses 3.00-inch polyurethane wheels. The four-way design requires smaller wheels for maneuverability and to fit within the wider fork assembly. Do not substitute a standard L50 wheel kit on a four-way jack, as the wheel size and axle geometry are incompatible.
Q: How do I diagnose wheel failure on the GWK-L504W-LW?
A: Inspect the carbon steel wheels for rust, pitting, flat spots, or cracks. Spin each wheel by hand; listen for grinding or feel for resistance, which indicates seized bearings. If the four-way jack is difficult to steer in a particular direction or pulls to one side, the wheel bearing may be failing. Test the jack with no load first to isolate wheel issues from hydraulic or frame problems. If wheels do not spin freely, replace the GWK-L504W-LW kit before operating under load.
Q: Can the GWK-L504W-LW wheels be replaced individually, or must the full kit be swapped?
A: The GWK-L504W-LW wheels are pre-assembled and sealed as a kit. Individual wheel replacement is not practical because the sealed bearing cartridges cannot be serviced. If one wheel fails, replace the entire GWK-L504W-LW kit to ensure even load distribution and consistent rolling resistance across all four wheels on the four-way platform.
Q: What tools do I need to install the GWK-L504W-LW, and how long does the job take?
A: You will need a socket set, adjustable wrench, and jack blocks or a lift to access the wheel axles safely. Plan 45 to 60 minutes for a four-way jack, as access is tighter than on a two-way model. Support the frame with blocks before removing fasteners. Install wheels hand-tight, then torque fasteners in a star pattern. Spin each wheel to confirm free rotation and test the jack in all four directions (forward, backward, left, right) before returning to service.
Q: Are the sealed ball bearings in the GWK-L504W-LW sealed for life, or do they need periodic maintenance?
A: The sealed ball bearings in the GWK-L504W-LW are factory-sealed and do not require lubrication or maintenance. The seals are not serviceable and cannot be removed without damaging the bearing races. Do not attempt to repack or regrease the bearings. When bearing wear develops (grinding noise, play, or resistance), replace the entire GWK-L504W-LW wheel assembly rather than attempting bearing repair.
