Frequently Asked Questions
Q: GWK-3KR84-LW comes in multiple material options—which wheel type should I order for my application?
A: GWK-3KR84-LW is available in four configurations: 92A durometer polyurethane for general warehouse use, 70D durometer polyurethane for cold storage and impact resistance, nylon wheels for cold storage environments (noise reduction), and steel wheels for locations with metal debris or ferrous materials. Most users order 70D Ultra-Poly as the default. Specify your application when ordering to ensure correct wheel hardness. Mixing wheel types on the same jack is not recommended and will cause tracking issues.
Q: Is GWK-3KR84-LW compatible with other Dayton Grainger pallet jack models besides 3KR84?
A: GWK-3KR84-LW is designed exclusively for Dayton Grainger model 3KR84 pallet jacks. It is not compatible with other Dayton Grainger model numbers or competing brands such as Uline or Harbor Freight. The axle diameter, bearing bore, and fastener spacing are specific to the 3KR84 frame geometry. Installing this kit on a different model will result in improper wheel alignment and unsafe operation. Always confirm your jack model before ordering.
Q: What tools and estimated time are needed to replace wheels with GWK-3KR84-LW?
A: You will need a socket set with appropriate sizes for the fasteners, an adjustable wrench, and a jack stand or forklift to safely lift the pallet jack. Wheel removal and installation typically requires 45-60 minutes for all four wheels (two load wheels and two steer wheels if applicable). No bearing puller or press is required since wheels are supplied as complete assemblies. Ensure the jack is secured on jack stands before beginning work. Always install fasteners in a cross pattern and torque to specification.
Q: What is the hardness rating of the 70D durometer wheels and why does that matter?
A: The 70D durometer rating means the polyurethane has a Shore D hardness of 70, which is softer than standard 92A wheels. Softer compounds (lower durometer numbers) flex more under load, absorbing impact and resisting shattering in cold storage environments where polyurethane becomes brittle. The 70D formulation also provides better traction on smooth concrete and reduced rolling resistance compared to harder wheels. Trade-off: they wear slightly faster in outdoor or abrasive environments but last much longer in controlled indoor settings.
Q: Does GWK-3KR84-LW include fasteners and can I reuse the old axles and bearings?
A: Yes, GWK-3KR84-LW includes new fasteners as part of the kit. You should not reuse old fasteners as they may have lost tension or developed micro-fractures. The kit includes hardened steel axles with protective coating. Do not attempt to reuse old axles if they show scoring, pitting, or wear. New bearings are pre-installed in the wheel assemblies and are sealed units. Replacing wheels without new fasteners risks wheel separation and creates a serious safety hazard.
Q: When should I replace GWK-3KR84-LW wheels and what visual signs indicate failure?
A: Replace wheels when flat spots, cracks, or chunks of material are visible. Operational indicators include increased pushing effort, noise during rolling, or the jack drifting to one side. In typical warehouse use with 70D wheels, expect 18-24 months of service. In cold storage, wheels may last longer due to reduced temperature cycling stress. Perform monthly visual inspections and quarterly load tests. Replace wheels before they reach 40 percent wear to ensure safe operation and prevent accelerated jack frame wear.
