Frequently Asked Questions
Q: What is included in the GWK-HPT28U-CK complete wheel kit?
A: GWK-HPT28U-CK is a complete wheel replacement kit that includes two Ultra-Poly 70D load wheel assemblies (3 inches wide by 3.75 inches diameter) and two polyurethane steer wheel assemblies (7 inches by 2 inches). All wheels come with factory-installed sealed bearings. The kit includes all mounting axles, fasteners, and installation hardware for Toyota HPT28U manual pallet jacks.
Q: Is GWK-HPT28U-CK compatible with Doosan HPT28 or other HPT28 variants?
A: No. GWK-HPT28U-CK is engineered exclusively for Toyota HPT28U pallet jacks. The wheel dimensions, bearing configuration, and axle pattern differ from Doosan HPT28 and older HPT28 models without the U suffix. Always verify your jack model before ordering. Cross-fitting incompatible wheels may result in improper bearing preload, steering issues, or safety hazards.
Q: What is the difference between load wheels and steer wheels in this kit?
A: Load wheels are the larger (3.75 inch diameter) wheels mounted at the rear of the jack and carry the lifted load. Steer wheels are smaller (7 inch by 2 inch) and mounted at the front for directional control. Load wheels use 70D Ultra-Poly for durability under heavy loads. Steer wheels use softer polyurethane for maneuverability. Do not interchange them.
Q: How do I determine if my Toyota HPT28U jack has the correct bearing type for this kit?
A: GWK-HPT28U-CK comes with sealed ball bearings pre-installed. Older HPT28U jacks may have open sleeve bearings. If your jack uses open bearings, verify axle diameter and width before purchasing. Most Toyota HPT28U production runs from 2005 onward use sealed bearings. Check the jack serial number or consult the OEM documentation. Installing sealed-bearing wheels on open-bearing axles requires spacer verification.
Q: What is the rated load capacity and operating environment for GWK-HPT28U-CK?
A: The kit supports a 5500 pound rated load capacity at a 24 inch load center, matching the Toyota HPT28U specification. The 70D Ultra-Poly durometer rating is suitable for indoor warehouse floors, concrete, and smooth asphalt surfaces. Do not use on rough, gravel, or uneven surfaces, as this accelerates wheel wear and may damage bearing seals.
Q: Can I order just the load wheels or just the steer wheels from GWK-HPT28U-CK?
A: GWK-HPT28U-CK is sold as a complete kit only. If you need only load wheels or steer wheels, contact the supplier for individual component SKUs. Many suppliers offer GWK-HPT28U-LW for load wheels only and separate steer wheel kits. Mixing kit components from different vendors requires verification of axle diameter, bearing preload, and fastener compatibility.
