Frequently Asked Questions
Q: What is included in the GWK-HPT28-LW load wheel kit?
A: The GWK-HPT28-LW includes two Ultra-Poly 70D load wheel assemblies complete with sealed bearings, case-hardened steel axles, and zinc-plated fasteners. This is a load wheel kit only and does not include steer wheels. It is designed as a direct replacement for Doosan HPT28 manual pallet jacks.
Q: Will GWK-HPT28-LW wheels fit Toyota or Presto pallet jacks?
A: No. GWK-HPT28-LW is engineered exclusively for Doosan model HPT28 pallet jacks. The wheel diameter, axle configuration, and mounting pattern are specific to Doosan equipment. Do not attempt to cross-fit to Toyota HPT28U or Presto HPT models without verification of axle centers and mounting hole locations.
Q: What is the rated load capacity and durometer rating of the GWK-HPT28-LW wheels?
A: The Ultra-Poly 70D wheels support the Doosan HPT28 jack rated load capacity of 5500 pounds at a 24 inch load center. The 70D durometer rating indicates a medium hardness suitable for moderate-floor abrasion and warehouse environments. This hardness balances wear resistance and ride smoothness.
Q: Can I replace only the load wheels on a Doosan HPT28, or must I replace steer wheels too?
A: Yes, you can replace load wheels independently. GWK-HPT28-LW provides two load wheel assemblies only. If steer wheels are worn or damaged, order those components separately. Mixing old and new wheels is acceptable from a mechanical standpoint but may cause uneven wear if the older wheels are significantly harder or softer.
Q: How do I know if GWK-HPT28-LW wheels are worn out and need replacement?
A: Signs of wear include visible cracks or chunks missing from the polyurethane tread, flat spots or severe gouging, wobbling or grinding noises during operation, and difficulty steering or load control. If wheels have been in service for 3+ years or show 50 percent of the original tread depth worn away, plan replacement. Check for axle play by lifting the jack and shaking the wheel side to side.
Q: What tools and installation steps are required to install GWK-HPT28-LW?
A: You will need a wrench set, jack stand or lift table, and cotter pin pliers. Remove the pin or snap ring securing each axle, slide off the old wheel assembly, and install the new assembly in reverse order. Ensure the bearing seal faces outward and the axle is fully seated. Do not over-tighten fasteners, as this can damage bearing seals. Installation typically takes 30 to 45 minutes per pair.
