The Honda 90554-728-940 Thrust Washer (20MM) is a genuine OEM component designed for HS55, HS70, and HS80 two-stage snow blowers. As a direct OEM replacement, this washer is manufactured to Honda's exact specifications, ensuring proper fitment without adjustment or rework. Sourced directly from Honda, this part carries the same specification as the original, so you can trust the fit right from the box. Confirm your snow blower's serial number against the fitment table before ordering, as Honda periodically supersedes parts at production serial breaks.
Key Features
- Genuine OEM Specification — manufactured by Honda to the same dimensional standard as the original, ensuring correct axial load transfer and running clearance within the drivetrain assembly.
- 20MM Sizing — the 20MM designation identifies this specific variant; verify this measurement matches your unit's requirement before ordering.
- Direct Fitment — designed for HS55, HS70, and HS80 two-stage snow blowers, including multiple production serial ranges; check your serial number against the fitment table to confirm the correct part for your machine.
- Wear-Sensitive Component — a worn or undersized thrust washer allows excess axial play in the shaft, which can accelerate wear on adjacent components and degrade drivetrain performance over time.
A thrust washer controls axial movement — the side-to-side or end-to-end travel — of a rotating shaft or gear within an assembly. By sitting between two moving faces, it absorbs the axial load that builds during operation and keeps the shaft positioned correctly. In a two-stage snow blower like the HS55, HS70, and HS80, where auger and impeller shafts work under significant load, a correctly fitted thrust washer is essential to smooth, controlled rotation. When a thrust washer wears thin or fails, excess play develops in the shaft, leading to noise, vibration, and accelerated wear on the surrounding components.
