GWK-JETJ-CK

Frequently Asked Questions

Q: What is included in the GWK-JETJ-CK complete wheel kit for Jet Model J?
A: The GWK-JETJ-CK is a complete wheel kit assembled for Jet Model J pallet jacks. It includes two load wheel assemblies, bearings, axles, and mounting fasteners. The kit is delivered pre-assembled and ready for installation onto your Model J frame carriage. No additional components are required.

Q: Can I use GWK-JETJ-CK on a Jet Model A or Model L frame?
A: No. The GWK-JETJ-CK is engineered for Jet Model J frames only. Axle bore spacing, fastener hole positions, and bearing housing dimensions are specific to Model J. Installing this kit on Model A or L will result in misalignment, play, or fastener breakage. Always verify frame model and use the correct SKU for your equipment.

Q: What wheel material and hardness rating is used in this kit?
A: The wheels are polyurethane with a 70D Shore durometer hardness rating. This formulation is oil-resistant, non-marking on sealed concrete, and shatterproof compared to hard plastic alternatives. The 70D rating provides a balance between load capacity and floor protection suitable for factory and warehouse environments.

Q: How long will this wheel kit last, and what are the failure indicators?
A: Expected service life under normal indoor use is 3 to 5 years. First signs of failure include flat spots on the wheel face, a grinding sound during rotation, visible wheel cracking, or resistance to smooth rotation. Once any of these appear, order a replacement kit. Continued use with damaged wheels risks bearing and frame damage.

Q: Are the bearings sealed and maintenance-free, or do they require periodic greasing?
A: Yes, the bearings are sealed at the factory and are lifetime-lubricated. No periodic greasing or relubrication is required or recommended. The seals cannot be removed without destroying the bearing. When a bearing fails after 3 to 5 years, replace the complete wheel assembly.

Q: What tools and installation time are needed to replace this kit on a Model J frame?
A: You will need a socket set (1/2-inch and 3/8-inch), a torque wrench, and jack stands. The frame must be removed from service and supported on stands during installation. Plan 30 to 45 minutes for removal of old wheels and installation of new assemblies. Use a torque wrench to tighten fasteners; do not overtighten or bearing seals will be damaged.
