Frequently Asked Questions
Q: What is the correct torque specification for GWK-P33-LW-XL axle nuts during installation?
A: Torque axle nuts to 45 to 55 foot-pounds for GWK-P33-LW-XL installations. Do not over-tighten, as this can crush bearing races and cause premature failure. After tightening, install a new cotter pin through the axle shaft hole and bend the pin ends to lock. Spin the wheel by hand to verify it rotates smoothly without binding. If resistance is felt, reduce torque slightly until smooth operation is confirmed.
Q: How do I identify if GWK-P33-LW-XL is the correct replacement for my specific Big Joe jack?
A: Locate your jack nameplate on the frame near the steering assembly. Verify it reads Big Joe P33. Measure existing wheel diameter and width using calipers or a ruler. GWK-P33-LW-XL wheels are exactly 3 inches diameter by 3.75 inches wide. If your existing wheels match these dimensions, GWK-P33-LW-XL is correct. If wheels are 3.0 x 3.5 inches, order GWK-P33-LW instead. Confirm part number before purchasing.
Q: Are the steel hubs on GWK-P33-LW-XL corrosion-resistant or do they require protective coating?
A: GWK-P33-LW-XL steel hubs are not stainless and will corrode if exposed to moisture or salt. Inspect hubs quarterly for surface rust. If rust appears, clean with a wire brush and apply a light coat of machine oil or rust inhibitor. In coastal environments or facilities with chemical exposure, apply protective grease after installation. Store spare wheel kits indoors in a dry location to prevent premature corrosion before use.
Q: What safety precautions must I follow during GWK-P33-LW-XL installation?
A: Secure the jack on a work stand or hydraulic lift before removing wheels. Do not work under an unsupported jack. Wear safety glasses to protect against bearing fragments if wheels are damaged. Keep hands clear of rotating wheels during test spin. Use proper lifting techniques when handling wheel assemblies, as they are heavy. Ensure all axle nuts and mounting hardware are tight before returning the jack to service. Test the jack on level ground with light load before resuming normal operation.
Q: Can GWK-P33-LW-XL wheels be used with non-Big Joe pallet jacks if the mounting points match?
A: No. GWK-P33-LW-XL wheels are engineered and load-rated for Big Joe P33 specifications only. Using them on other brands may exceed wheel load capacity or create safety hazards. Even if physical mounting appears possible, do not substitute. Each pallet jack manufacturer designs wheels for specific load distributions and platform geometry. Using incorrect wheels voids warranties and creates liability. Always use wheels specified for your exact jack model and brand.
Q: How do sealed ball bearings on GWK-P33-LW-XL compare to open bearings in terms of maintenance?
A: Sealed ball bearings require zero scheduled lubrication and resist contamination from dirt, moisture, and debris. Open bearings require periodic regreasing and are prone to premature wear in dirty environments. GWK-P33-LW-XL sealed bearings reduce maintenance time and improve reliability. However, if a seal is damaged, the bearing cannot be serviced and the entire wheel must be replaced. Sealed bearings cost more upfront but save labor and extend service intervals, making them ideal for high-use fleets.
