Frequently Asked Questions
Q: What are the dimensions and material specifications for the HY 4081639-XL load wheel?
A: The HY 4081639-XL is an 85 mm diameter by 110 mm width polyurethane load wheel assembly with a nominal hardness of 95 Shore A. The wheel is designed for pallet trucks and similar material handling equipment where consistent rolling characteristics and load support are required.
Q: Which pallet truck and lift equipment brands does the HY 4081639-XL fit?
A: The HY 4081639-XL is an OEM Hyster load wheel assembly. It is compatible with Hyster pallet trucks and material handling equipment configured with this wheel size and mounting interface. Verify your equipment model and wheel mounting specifications before ordering to ensure correct fitment.
Q: How does 95 Shore A polyurethane hardness affect wheel performance and lifespan?
A: 95 Shore A polyurethane provides a balanced compound for general material handling applications. This hardness level offers moderate wear resistance and grip on dry concrete and finished warehouse floors. Wheels at this hardness typically wear gradually over 12 to 24 months of regular use, depending on load volume, floor conditions, and maintenance practices.
Q: What is the load capacity for the HY 4081639-XL wheel assembly?
A: Load capacity specifications for the HY 4081639-XL are determined by the complete equipment assembly and wheel mounting configuration. Consult Hyster technical documentation or your equipment manual for rated load limits, as wheel performance is rated within the context of the full pallet truck system.
Q: Are there cross-reference part numbers for the HY 4081639-XL?
A: The HY 4081639-XL carries OEM part number HY 4081639-XL with manufacturer part number 4081639. Cross-references to aftermarket equivalents depend on exact wheel diameter, width, and bearing type. Contact our technical team with your equipment model and current wheel specifications for compatible alternatives.
Q: What maintenance extends the life of the HY 4081639-XL load wheel?
A: Inspect wheels regularly for flat spots, cracks, or uneven wear. Keep wheels clean and free of debris buildup. If your equipment has lubricated bearings, verify bearing condition periodically. Replace wheels promptly if diameter wear exceeds 10 percent or if the wheel becomes unstable, as this compromises equipment handling and load security.
