Frequently Asked Questions
Q: What diameter and thickness is the 21598800 washer?
A: The 21598800 is a flat washer for electric lift truck assemblies. Confirm the inner diameter, outer diameter, and thickness specifications match your fastening application before ordering.
Q: Which electric truck components use the 21598800 washer?
A: The 21598800 washer is used in load wheel axles, steering linkages, and brake assemblies on electric lift trucks from Crown, Toyota, and Raymond. It distributes load and prevents fastener pull-through on these critical assemblies.
Q: What material is the 21598800 washer made from?
A: The 21598800 is a steel washer with zinc or nickel plating for corrosion resistance. Steel construction handles the bearing loads in electric truck assemblies while plating protects against rust and moisture.
Q: Why should washers be used with fasteners on lift trucks?
A: Washers distribute fastener load across a larger area, preventing nuts and bolts from sinking into softer metals or loosening under vibration. On electric trucks, washers reduce fastener migration that can occur during hundreds of load cycles.
Q: Can the 21598800 washer be reused?
A: Washers can be reused if they remain flat and show no cracks, permanent deformation, or rust pitting. If a washer has been compressed, cracked, or shows deep corrosion, replace it with a new 21598800 to maintain load distribution.
