The Honda 90557-461-000 Special Washer (10MM) is a genuine OEM component designed for HRB215 and HRM215 lawn mowers. As a direct Honda OEM part, it is produced to the exact dimensions and tolerances specified for these mowers, ensuring a proper fit without modification. Sold by DHS Equipment, this washer is sourced directly through Honda's authorized parts network, so you can order with confidence knowing you are receiving an authentic replacement. Confirm your mower's serial number against the fitment table before ordering to make sure part number 90557-461-000 is the correct match for your specific unit.
Key Features
- Genuine OEM Specification — produced by Honda to the exact dimensional tolerances required for the HRB215 and HRM215, so the washer seats and functions exactly as the original did.
- Correct 10MM Sizing — the (10MM) designation identifies this as a specific variant; verify this size matches your mower's requirement before ordering.
- Serial Number Awareness — Honda updates parts at production breaks, so cross-check your mower's serial number against the fitment table to confirm this is the right washer for your machine.
A special washer like this one is engineered to a specific outer diameter, inner diameter, and thickness that differs from a standard flat washer of the same nominal size. In a lawn mower application, the precise dimensions ensure correct clamping load and component alignment at the point where it is installed. Using the wrong washer — one that is too thick, too thin, or the wrong diameter — can result in improper fastener torque, component looseness, or accelerated wear, making the exact OEM specification critical for a lasting repair.
