The Honda 90456-MA6-000 Thrust Washer (25MM) is a genuine OEM replacement designed for HS522 and HS622 two-stage snow blowers. As an authentic Honda part, it meets the same specifications as the original component installed at the factory. This Thrust Washer (25MM) is the correct service part for these machines, and buyers should confirm their unit's serial number against the fitment table to ensure this is the right version for their specific build.
Key Features
- Genuine OEM Part — sourced directly from Honda, so the dimensions and material tolerances match the original exactly, ensuring the washer seats and functions as intended in the drivetrain assembly
- Correct 25MM Sizing — the (25MM) designation identifies this specific variant; verify this matches your snow blower's requirement before ordering
- Two-Stage Snow Blower Fitment — listed for HS522 and HS622 two-stage snow blowers; check your serial number against the compatibility table to confirm applicability to your machine
- Axial Load Management — a properly functioning thrust washer controls axial movement and prevents premature wear on adjacent rotating components, keeping the auger or drive system operating smoothly
A thrust washer is a flat bearing component that absorbs axial (end-to-end) loads between rotating and stationary parts, preventing metal-to-metal contact along the shaft. In a two-stage snow blower like the HS522 and HS622, thrust washers are used at key points in the auger and drive assemblies to manage the forces generated during operation. When a thrust washer wears out or is missing, the affected shaft develops excessive end-play, which accelerates wear on surrounding components and can lead to noise, vibration, or loss of drive efficiency.
