Frequently Asked Questions
Q: What is included in the GWK-HPT55-LW load wheel kit?
A: GWK-HPT55-LW is an OEM load wheel replacement kit engineered for Presto HPT 55 Series manual pallet jacks. The kit includes two polyurethane tread load wheels, sealed deep groove ball bearings, zinc-plated high tensile steel axles, copper alloy bushings, and hardened spring pin fasteners. All components are pre-assembled and ready for direct installation.
Q: Is GWK-HPT55-LW compatible with Toyota HPT55, or only Presto HPT55?
A: The product information indicates compatibility with Toyota model HPT55, though the description references Presto HPT55 Series. This suggests Toyota may use Presto-manufactured or interchangeable HPT55 assemblies. Verify your jack manufacturer name and model number before ordering. Contact the supplier with your jack serial number or OEM documentation if you are uncertain about compatibility.
Q: What load capacity and durometer rating do GWK-HPT55-LW wheels support?
A: GWK-HPT55-LW wheels support a rated 5500 pound capacity at a 24 inch load center, matching the HPT55 jack specification. The polyurethane hardness is typically 70D durometer, providing a balance of wear resistance and floor compliance. The wheel design, axle material, and bearing configuration are all engineered for this load rating. Exceeding the rated capacity will cause premature bearing wear and seal failure.
Q: What role do copper alloy bushings and spring pins play in GWK-HPT55-LW?
A: Copper alloy bushings reduce friction between the axle and wheel bore, improving rotation efficiency and extending bearing life. Hardened spring pins secure the wheel to the axle without the need for cotter pins or snap rings, reducing assembly time and improving reliability. This design is typical of OEM equipment engineered for high-cycle durability in demanding warehouse environments. Do not substitute with lower-grade fasteners.
Q: How do I diagnose wheel failure on an HPT55 jack using GWK-HPT55-LW?
A: Perform a spin test by lifting the jack on a stand and rotating each wheel by hand. Listen for grinding, squeaking, or rough spots. Wheels should spin freely without noise. Visual signs of failure include cracks, flat spots, missing tread chunks, and discoloration from heat or overload. If the jack is difficult to steer or control, wheels may be failing. Wobbling at low speeds indicates bearing damage. Replace the kit if any of these signs appear.
Q: What is the installation procedure and expected service life of GWK-HPT55-LW?
A: Installation requires wrenches and a lift table or jack stand. Remove the spring pins or fasteners securing the old axle assembly, slide off old wheels, and install new assemblies in reverse order. Verify spring pins are fully seated. Do not over-tighten fasteners. Installation typically takes 30 to 45 minutes. The sealed bearing and quality axle material are designed for 3 to 5 years of service under moderate warehouse use. Routine inspection will help identify wear early.
