The Honda 90451-107-000 Thrust Washer (15MM) is a genuine OEM component designed for the HR21 lawn mower. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring a correct fit within the mower's assembly. Verify your unit's serial number against the fitment table to confirm this is the right listing for your machine before ordering.
Key Features
- Genuine OEM Construction — sourced directly from Honda, this washer matches the original part in every dimension, so it seats and functions exactly as the mower was built to operate.
- Correct 15MM Sizing — the 15MM designation identifies this specific variant; confirm it matches your original before ordering, as alternative sizes may be listed separately.
- HR21 Lawn Mower Fitment — listed for the Honda HR21 mower; check your serial number against the compatibility table to ensure this is the correct supersession for your production range.
A thrust washer controls axial movement between rotating or sliding components, keeping them correctly positioned against each other during operation. In the HR21 lawn mower, this washer absorbs the lengthwise load on a rotating shaft or spindle, preventing metal-to-metal contact and reducing wear on the parts it sits between. When a thrust washer wears thin or goes missing, the components it spaces can shift out of position, leading to increased wear, noise, or loss of smooth operation in that assembly.
