Frequently Asked Questions
Q: What are the key material and dimension differences between the 95A and 97A hardness versions?
A: The TO 00590-04780-71-A-XL features 97A Shore hardness polyurethane tread, compared to the standard 95A version. Both wheels share the same dimensions. The 97A compound provides greater hardness and resistance to cuts, abrasion, and rolling wear, making it better suited for high-mileage continuous-duty environments and rougher floor surfaces.
Q: Which Toyota models accept the TO 00590-04780-71-A-XL replacement wheel?
A: The 97A hardness variant is compatible with Toyota 6HBW30, 7HBW30, 8HBW30, 8HBE30, and 8HBE40 pallet trucks. Mounting specifications remain identical to the 95A standard version. Check your equipment serial range against Toyota cross-reference documentation to confirm model compatibility before ordering.
Q: What part numbers supersede or replace the TO 00590-04780-71-A-XL?
A: The TO 00590-04780-71-A-XL supersedes and replaces TY00590-04780-71-AS, TY00590-04780-71-MIL-AS, TY00590-04780-71-MIL-THO, and TY00590-04780-71-MIL-SUP. It is equivalent to TO005900478071. When ordering, use the full part number TO 00590-04780-71-A-XL to ensure you receive the 97A hardness specification.
Q: Does the 97A hardness wheel provide better performance in continuous-duty applications?
A: Yes, the 97A Shore hardness compound is engineered for continuous-duty operation with higher resistance to deformation, wear, and damage from extended load cycles and frequent operation. It maintains dimensional stability longer under sustained use and delivers reduced rolling resistance, improving truck efficiency over extended operating periods compared to softer compounds.
Q: What floor types are most suitable for the 97A polyurethane compound?
A: The 97A hardness polyurethane provides stable performance on concrete, sealed asphalt, and polished warehouse floors. It generates more noise on extremely hard surfaces but resists deformation and maintains consistent rolling diameter. For wet floor or extremely slippery surfaces, the increased hardness may reduce traction. Evaluate your floor conditions against polyurethane durometer ratings before selecting 97A over 95A.
