GWK-HPT55-CL

Frequently Asked Questions

Q: What components are included in the GWK-HPT55-CL complete wheel kit?
A: GWK-HPT55-CL is a complete wheel kit for Presto HPT55 series manual pallet jacks that includes load wheels and steer wheels. All wheels feature Ultra-Polyurethane 70D durometer tread, sealed ball bearings, hardened SAE 1045 steel axles, and bolt-on fasteners. The kit provides all components necessary for direct replacement on HPT55 equipment.

Q: Is GWK-HPT55-CL compatible with Toyota HPT55, or is it Presto-only?
A: The product information indicates compatibility with Toyota model HPT55, though the description references Presto HPT55 Series. This may indicate that Toyota acquired or rebranded Presto HPT55 units, or both manufacturers use interchangeable wheel assemblies. Verify your jack manufacturer and serial number before purchase. If uncertain, contact the supplier with your jack model and serial range.

Q: What is the rated load capacity and suitable operating environment for GWK-HPT55-CL?
A: The HPT55 series jack typically supports a 5500 pound rated load capacity. The 70D durometer polyurethane wheels are designed for indoor warehouse floors, concrete, and smooth surfaces. The high-impact thermoplastic wheel core provides impact resistance. Do not operate on rough, gravel, or sloped surfaces, as this accelerates wear and bearing damage.

Q: How do I identify failing wheels on my HPT55 jack?
A: Signs of wear include visible cracks, chunks missing from the polyurethane tread, flat spots or gouges, grinding or squeaking noises, and difficulty steering or controlling load. Perform a manual spin test by lifting the jack on a stand and rotating each wheel by hand, listening for grinding. If wheels do not spin freely or make noise, bearing failure is likely. Replace the kit immediately if any signs are present.

Q: What is the difference between the thermoplastic wheel core and the polyurethane tread in GWK-HPT55-CL?
A: The high-impact thermoplastic core provides structural rigidity and impact resistance to support the load capacity and withstand shocks during operation. The Ultra-Polyurethane 70D tread is the wear surface that contacts the floor. The thermoplastic resists cracking under load, while the polyurethane provides traction and wear resistance. This two-layer design extends wheel life compared to solid polyurethane wheels.

Q: What installation and maintenance procedures apply to GWK-HPT55-CL?
A: Installation requires wrenches, a lift table, and basic mechanical skill. Remove fasteners, slide off old wheels, and bolt new assemblies in place. The sealed bearing design requires no grease maintenance. Inspect wheels monthly for damage and debris. Keep wheels clean and dry. Store the jack in a climate-controlled space. Service life typically is 3 to 5 years. Replace immediately if wheels wobble, squeak, or fail to spin freely.
