Key Features
- Genuine Honda OEM — sourced directly from Honda, this wave washer matches the original part your equipment left the factory with, ensuring the correct fit and function for part number 90404-723-000.
- Broad Equipment Coverage — listed for the EX5500 generator, multiple F-series and FR-series tillers, and HS521 and HS621 single-stage snow blowers, making this a widely used Honda hardware component.
- Serial Number Verification Recommended — Honda updates parts at production serial breaks, so check your machine's serial number against the fitment table to confirm this is the right wave washer for your unit.
A wave washer is a thin, corrugated ring that provides a controlled spring load between mating components. Its wavy profile compresses under assembly to take up axial play, maintain preload, and prevent loosening caused by vibration during operation. When a wave washer is missing or has lost its spring tension, the components it loads can develop unwanted play, leading to noise, wear, or improper function of the assembly it belongs to.
