GWK-HPT28-CK

Frequently Asked Questions

Q: Is the 0000-72008 compatible with Doosan HPT28 or other Doosan models?
A: The 0000-72008 is designed exclusively for the Doosan HPT28 manual pallet jack. Do not use this kit on Doosan HPT20, HPT25, HPT30, or other models. The HPT28 frame has unique axle diameters, mounting hole patterns, and steer wheel geometry that differ from other Doosan models. Installing the wrong wheel kit will result in poor fitment, bearing misalignment, and operational hazards. Always confirm your pallet jack is a Doosan HPT28 before ordering.

Q: What wheels and components are included?
A: This is a complete wheel kit including: two ultra-poly (Shore D 70 hardness) load wheel assemblies, two poly steer wheel assemblies, sealed bearings pre-installed on all wheels, steel axles, and fastening hardware. All wheel-axle subassemblies arrive pre-assembled with bearings installed.

Q: Can I order just the load wheels or steer wheels?
A: The kit is sold as a complete four-wheel set. If only load wheels are damaged, you may request a partial kit through parts sourcing, but this typically requires special order and longer lead time. For immediate replacement and balanced wheel aging, order the complete kit. Replacing all four wheels as a matched set ensures uniform rolling characteristics and bearing lifespan across the entire jack.

Q: What load capacity is this wheel kit designed for?
A: The wheels are engineered for the full duty capacity of the Doosan HPT28 frame, which is typically 2500-3000 lb at 24 inch load center (verify your specific frame nameplate). The ultra-poly and poly steer wheel construction is rated for standard warehouse use on smooth concrete floors with evenly distributed loads. Do not exceed the HPT28 frame capacity rating.

Q: How do I diagnose whether wheels or bearings are failing?
A: Early signs of wheel or bearing failure include audible grinding, squealing, or rumbling when rolling the jack; increased effort required to move or steer; jack pulling or drifting to one side when not steered; visible flat spots, cracks, or chunks missing from wheel perimeter; wheels that do not spin freely when jack is lifted; or visible wear deeper than 1/8 inch into the wheel surface.

Q: What is the rated floor environment for these wheels?
A: These wheels are rated for smooth, level concrete warehouse floors with standard 8-10 hour daily shifts. Operation on uneven, outdoor, or heavily textured floors will reduce wheel lifespan by 40-60 percent and increase bearing stress. Indoor, climate-controlled use on clean concrete provides maximum wheel and bearing durability.

Q: How long do these wheels typically last?
A: Wheel lifespan depends on usage intensity, floor type, and load distribution. Under standard warehouse conditions (smooth concrete, rated capacity, 8-10 hour shifts), expect 3-5 years of service before bearing wear or wheel degradation requires replacement. Heavy-duty or outdoor use significantly reduces lifespan. Inspect wheels quarterly for wear and bearing noise.

Q: How should these wheels be stored before use?
A: Store wheels indoors in a dry, climate-controlled environment away from direct sunlight, moisture, and extreme temperatures. Keep sealed bearings protected from contamination. Store on a flat surface to prevent bearing stress. Avoid stacking heavy items on wheels during storage, as this can damage seals or create internal bearing misalignment.
