The Honda 90451-436-000 Thrust Washer (19.5MM) is a genuine OEM replacement designed for HRA216, HRC215, and HRC216 lawn mowers. As a direct Honda OEM part, this thrust washer is manufactured to the exact dimensions required for proper axial load control within the mower's drive components. Confirm your mower's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct washer for your unit depends on your specific production range. This is the 19.5MM variant — verify that this size matches your machine's requirement.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this thrust washer meets the exact dimensional tolerances the HRA216, HRC215, and HRC216 mowers demand for correct axial load management.
- 19.5MM Variant — the size designation is part of your selection: match this measurement to your mower's specification before ordering, particularly if multiple listings exist for this application.
- Serial Number Matters — Honda updates parts at specific serial breaks, so cross-reference your mower's serial number with the fitment table to confirm this is the correct washer for your unit.
- Correct Fit Prevents Wear — an undersized or oversized thrust washer allows unwanted axial play, accelerating wear on adjacent rotating components and leading to premature drivetrain service.
A thrust washer controls axial movement between rotating and stationary components, absorbing the load that tries to push those parts along their axis of rotation. In a walk-behind lawn mower, thrust washers are used at points in the drive system where spinning shafts or hubs generate this side-loading force. When a thrust washer wears thin or is missing entirely, the parts it separates begin to contact each other directly, causing accelerated wear, increased friction, and eventual damage to the surrounding assembly. Replacing a worn washer with the correct OEM part restores the designed clearance and protects the components around it.
