Frequently Asked Questions
Q: What is the purpose of the TO 00591-76087-81 flat washer?
A: The TO 00591-76087-81 is a Toyota OEM flat washer used in wheel assembly fastening systems on electric lift trucks. Flat washers distribute the load of fastener heads across a wider surface area, reduce stress concentration on components, and prevent fasteners from pulling through softer materials.
Q: Which fastener applications use this washer in Toyota electric lift trucks?
A: The TO 00591-76087-81 washer is typically paired with lug bolts, studs, and structural fasteners in wheel hubs, brake assemblies, and axle mounting points on Toyota electric lift trucks. It is designed to work in conjunction with OEM bolts and nuts in material handling applications.
Q: What is the material and finish of this flat washer?
A: Toyota OEM flat washers are manufactured from steel and typically receive a zinc-plated or electroplated finish for corrosion resistance. The finish protects against rust in warehouse and outdoor material handling environments, extending service life and preventing fastener seizure.
Q: How many flat washers are needed for a complete fastener assembly?
A: Typically one flat washer is used per fastener. For a complete wheel assembly replacement, order washers in the same quantity as your lug bolts or studs. Inspect existing fastener patterns before ordering to confirm the exact washer count needed for your application.
Q: Are there cross-reference part numbers for this washer?
A: No known cross-reference or superseding part numbers exist for TO 00591-76087-81. This is a Toyota OEM part number. If substitute washers are required, ensure they match the inner diameter, outer diameter, and material specification of the original OEM part.
