Frequently Asked Questions
Q: Does the GWK-L50-CK work on both Lift-Rite and Big Joe L-50 models?
A: Yes. The GWK-L50-CK is compatible with both Lift-Rite L-50 and Big Joe L-50 manual pallet jacks. These brands share the same platform and mounting geometry. Always verify your jack serial range with the manufacturer to confirm that you have the L-50 designation, as other models in the Lift-Rite and Big Joe families may require different wheel kits.
Q: What is included in the GWK-L50-CK, and why do I need both load and steer wheels?
A: The GWK-L50-CK is a complete wheel assembly kit that includes ultra-polyurethane load wheels (70 Shore D) for the rear forks and nylon composite steer wheels for the front castor. Load wheels carry the pallet weight and require harder compound for durability. Steer wheels guide direction and are softer nylon for floor protection and maneuverability. Both must function properly for safe operation.
Q: The GWK-L50-CK has pre-installed bearings. Can I reuse them if I only replace the wheel tread?
A: No. The sealed ball bearings in the GWK-L50-CK are permanently seated in the wheel hub. If you need to replace only the wheel tread material due to damage, you must purchase a new complete wheel assembly. Attempting to remove and reinstall bearings will damage the seals and bearing races.
Q: How do I install the GWK-L50-CK on an L-50 with a 1.75-inch axle?
A: The GWK-L50-CK is pre-engineered for the 1.75-inch axle standard on L-50 models. Remove the old wheel assembly by unbolting the axle hardware at both the front and rear fork attachment points. Slide the new wheel assembly onto the axle, align the retention clips, install fastening hardware, and torque to secure. Test wheel spin by hand before operating the jack under load.
Q: What is the service life of the GWK-L50-CK wheels in a high-traffic warehouse?
A: Under typical warehouse use (10 to 15 jack cycles per hour on concrete floors), the GWK-L50-CK load wheels last 2 to 3 years before visible wear develops. Steer wheels may need replacement sooner due to greater directional stress. Inspect wheels quarterly for flat spots, cracks, or edge delamination. Sealed bearings typically outlast the wheel tread and do not require separate maintenance.
Q: Can I use the GWK-L50-CK on damp or outdoor surfaces?
A: Yes. The ultra-polyurethane load wheels and sealed bearings are designed for damp concrete and light outdoor use. The sealed bearing cartridges prevent moisture ingress. However, avoid prolonged standing water or freezing conditions, as expansion and contraction can stress the axle and fork attachment points. Clean and dry the wheels after outdoor exposure to prevent salt corrosion of the steel axle.
