Frequently Asked Questions
Q: What is the GWK-JETJ-LW designed for, and which Jet models does it fit?
A: The GWK-JETJ-LW is a load wheel replacement kit engineered specifically for Jet J Series PT 2748 manual pallet jacks. It contains two dual Ultra-Poly 70D durometer wheel assemblies with sealed precision bearings, heat-treated steel axles, and zinc-plated fasteners. This is not a universal kit; installation on Model A or L frames will not align properly.
Q: Is GWK-JETJ-LW equivalent to GWK-JETJ-CK, or are these different assemblies?
A: GWK-JETJ-LW and GWK-JETJ-CK are both complete wheel kits for Jet Model J. Both include the same 70D polyurethane wheels and sealed bearings. The naming convention (LW for load wheel, CK for complete kit) reflects different packaging or supplier designations, but the components are functionally identical. Verify part availability with your distributor before ordering.
Q: What are the wheel hardness and material specifications, and are they oil-resistant?
A: Wheels are Ultra-Polyurethane with 70D Shore A hardness per ASTM standards. This formulation is oil-resistant and will not soften or degrade when exposed to hydraulic fluid, machine oil, or light solvents. Long-term exposure to strong aromatics (acetone, benzene) may soften the surface. The 70D rating is mid-range hardness, balancing load capacity and floor protection.
Q: What is the maximum load capacity of this kit, and how do I verify I am not overloading it?
A: The kit supports the rated capacity of your Jet PT 2748 J pallet jack (consult the frame capacity plate for exact tonnage, typically 2,500 to 5,000 pounds). Signs of overload include flat spots on the wheel, difficulty steering, or bearing noise within weeks. Do not exceed the frame nameplate rating; overload causes accelerated bearing wear and permanent frame damage.
Q: Are the bearings sealed and maintenance-free, or do they require relubrication?
A: The sealed precision ball bearings are pre-lubricated at the factory and require no user maintenance. The seals are permanent; do not attempt to disassemble or relubricate. Bearing life is typically 3 to 5 years under normal use. When grinding noise or wheel wobble appears, replace the entire assembly; bearing repair is not field-serviceable.
Q: What installation steps and tools are required, and can this be done in-place on a working truck?
A: You will need a socket set, torque wrench, and jack stands. The truck must be removed from service and the carriage supported on stands; in-place installation risks personal injury and improper fastener torquing. Remove old wheels by unbolting the axles, slide new assemblies onto the frame bores, thread fasteners, and tighten to specification (typically 40 to 50 foot-pounds for Grade 5 fasteners). Plan 45 minutes for both wheels.
