Frequently Asked Questions
Q: What are the core specifications for this Toyota caster wheel?
A: This wheel assembly features a polyurethane construction with 95A durometer hardness. The precision-machined seats accurately on Toyota walkie jack axles. The wheel is molded on a steel core with sealed ball bearings, providing sealed performance without contamination.
Q: Which Toyota electric pallet truck models are compatible?
A: This wheel assembly is compatible with Toyota 6HBW30, 7HBW30, 8HBW30, 8HBE30, and 8HBE40 series electric pallet trucks in both walkie and walkie-rider configurations. Verify your specific truck model and serial range documentation to confirm compatibility before purchasing.
Q: What are the cross-reference and variant part numbers?
A: Direct cross-references include TY 00590-04780-71-XL-A, TO00590-04780-71-XL-A, and TY00590-04780-71-XL-A. Base part variants are TO 00590-04780-71, TY00590-04780-71, and 005900478071. An alternate assembly configuration with 97A durometer hardness is available as TO 00590-04780-71-A-XL for higher wear resistance applications.
Q: Why is the 2.047 inch bore diameter specification important?
A: The is precision-engineered for Toyota walkie jack axles across the 6HB, 7HB, and 8HB series. This exact dimension ensures proper seating, minimal lateral play, and correct wheel alignment during operation. Verify bore compatibility against your equipment specifications to prevent fit issues.
Q: What is the difference between the 95A and 97A durometer options?
A: The 95A version provides balanced grip and moderate wear resistance for standard warehouse environments on dry and slightly damp floors. The 97A variant offers increased durometer hardness for extended wear life, cut resistance, and continuous heavy-duty or high-mileage operation. Select 95A for routine warehouse use and 97A for demanding material handling conditions.
Q: How should this wheel be stored and maintained?
A: Store in a cool, dry location away from direct sunlight and extreme temperatures to prevent polyurethane degradation. Keep wheel surfaces clean and inspect bearings periodically for proper rotation and smooth operation. Do not store near solvents or chemicals that may degrade polyurethane material.
