Frequently Asked Questions
Q: Is the GWK-HY55-LW compatible with both standard and nylon HY55 models?
A: The GWK-HY55-LW is the ultra-poly 70D load wheel kit. It fits Hyster HY55 models that use polyurethane load wheels. If your HY55 has nylon wheels, you need the GWK-HY55N-LW instead. Check your jack nameplate or inspect the wheel material before ordering.
Q: What is the wheel size on the GWK-HY55-LW?
A: The GWK-HY55-LW provides two load wheels measuring 3 x 3.75 inches with ultra-polyurethane construction at 70D hardness. This size and material are standard for HY55 jacks used in general warehouse and dock operations.
Q: Can I use the GWK-HY55-LW in cold storage or outdoor applications?
A: The 70D polyurethane wheels will harden and lose grip in cold storage below 32 degrees Fahrenheit. For cold storage, switch to the GWK-HY55N-LW nylon wheels, which remain flexible and non-marking at low temperatures. Do not use poly wheels outdoors in direct sun; UV exposure cracks the material.
Q: What does sealed ball bearing mean, and do I need to grease these wheels?
A: Sealed ball bearings are enclosed with a protective shield that keeps dirt and debris out. These bearings are pre-lubricated from the factory and require no additional grease. Over-greasing will damage the seal and cause premature bearing failure.
Q: What is the difference between GWK-HY55-LW and GWK-HY55N-LW?
A: GWK-HY55-LW uses ultra-poly 70D hardness wheels for general warehouse use. GWK-HY55N-LW uses nylon wheels and is designed for cold storage and non-marking applications. Nylon wheels are silent and safer for food/pharma environments. Poly wheels are more durable in high-heat and general-duty settings.
Q: How do I diagnose if my HY55 load wheels are failing?
A: Signs include flat spots on the wheel surface, visible cracks or gouges, side-to-side wobble at the axle, or the jack pulling hard to one side during operation. If wheels are chunked or shredded, replace immediately to avoid damage to the jack frame and ensure operator safety.
