Sourced directly from Honda, this washer carries the same specifications as the original, so it drops in without modification. If you are working on an HR17, confirm your unit's serial number against the fitment table before ordering, as Honda updates part numbers at production breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, identical to the original washer that shipped with your HR17 lawn mower
- Exact Replacement — matches the original part number 90426-437-000 for a straightforward, no-guesswork installation

A rotor setting washer is a precision flat washer used to establish and maintain the correct axial positioning of a rotor within an assembly. By controlling the spacing and load distribution at that point, it prevents unwanted movement that could lead to wear or misalignment over time. When the original washer is worn, damaged, or missing, proper rotor seating is compromised and the assembly may not function as intended.
