The Honda 90455-729-300 Thrust Washer B (12mm) is a genuine OEM component designed for F210 tillers and HR195, HR215, and HRA215 lawn mowers. As an authentic Honda part, it is manufactured to the same specifications as the original, ensuring a direct, accurate fit with no guesswork. Always confirm your machine'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 the production range. This Thrust Washer B (12mm) is the right part to have on hand for any scheduled service or drivetrain repair on these Honda machines.
Key Features
- Genuine OEM Fit — sourced directly from Honda, this washer matches the original dimensional tolerances so it seats correctly without shimming or modification.
- Correct Variant — the 12mm designation identifies this as the specific size required; confirm this matches your machine's application before installation.
- Broad Fitment — listed for the F210 tiller and HR195, HR215, and HRA215 lawn mowers; verify your serial number against the fitment table to confirm applicability to your unit.
- Serial-Range Awareness — Honda updates part numbers at production breaks, so cross-reference your machine's serial number with the compatibility chart to ensure this is the current correct part for your build.
A thrust washer controls axial movement between rotating or sliding components by providing a low-friction bearing surface that absorbs forces acting along a shaft's axis. In tillers and walk-behind mowers, these washers are used within drivetrain and transmission assemblies to maintain proper spacing and prevent metal-on-metal wear between adjacent rotating parts. When a thrust washer wears thin or is missing entirely, excessive play develops along the shaft, leading to accelerated component wear, noise, and degraded drive performance.
