Frequently Asked Questions
Q: Is the GWK-CJ55-CK compatible with my Clark CJ55 pallet jack?
A: Yes. The GWK-CJ55-CK is a direct replacement complete wheel kit engineered specifically for Clark CJ55 manual pallet jacks. It includes both load wheels (2x Ultra-Poly 70D) and steer wheels (2x poly), plus all bearings, axles, and fasteners needed for assembly. Verify your jack model number matches CJ55 before ordering.
Q: What is the difference between 70D Ultra-Poly wheels and standard wheels?
A: Ultra-Poly 70D wheels are formulated to be harder and more durable than standard polyurethane. 70D wheels have a longer operational lifespan, roll more smoothly with less operator fatigue, and resist wear in high-volume warehouse use. The primary trade-off is slightly less shock absorption on uneven surfaces. For continuous operations and extended shifts, 70D offers superior performance.
Q: How many wheels are included in the kit?
A: The GWK-CJ55-CK includes four complete wheel assemblies: two Ultra-Poly 70D load wheel assemblies and two standard poly steer wheel assemblies. Each assembly includes the wheel, integrated bearings, and all necessary fasteners for the Clark CJ55.
Q: Can I replace just one or two wheels, or must I replace all four?
A: Replacing all four wheels together is strongly recommended. Mixing new and old wheels creates uneven roll resistance and handling imbalance, which can force operators to apply uneven pressure and accelerate wear on remaining older wheels. Replacing the complete set ensures optimal performance and consistent operational handling.
Q: What are the signs that wheels need replacement?
A: Replace wheels when you observe flat spots, visible cracks, chunks missing from the wheel surface, or excessive noise during operation. If the pallet jack drifts sideways under load despite steering input, this is another indicator of wheel wear. A simple check: spin each wheel by hand—it should rotate freely without binding or unusual sound.
Q: How long do Ultra-Poly 70D wheels typically last?
A: Lifespan depends on usage intensity and floor conditions. In typical warehouse environments with regular use, Ultra-Poly 70D wheels generally maintain performance for 12-24 months before showing signs of wear. High-volume operations may see shorter lifespan; light-duty applications may extend beyond 24 months. Proper wheel maintenance and smooth surfaces extend durability.
Q: What floor surfaces work best with these wheels?
A: The GWK-CJ55-CK wheels perform well on concrete, sealed concrete, epoxy floors, and polished surfaces typical in warehouses and logistics facilities. On rough or uneven surfaces, wheels may wear faster and provide a less smooth rolling experience. Avoid dragging or prolonged contact with sharp objects or abrasive materials.
