The Honda 90450-147-000 Thrust Washer (8MM) is a genuine OEM component designed for GV400 vertical shaft engines and H3011 and H3013 riding mowers. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring an exact match to the factory assembly. Honda supersedes parts at serial-number breaks, so confirm part number 90450-147-000 against the fitment table before ordering to make sure this is the correct thrust washer for your machine.
Key Features
- Genuine OEM Fit — sourced directly from Honda, this washer matches the original dimensions and tolerances required for correct axial load management in the assembly
- 8MM Variant — the (8MM) designation identifies this specific size; verify your unit calls for this variant before purchasing
- Broad Compatibility — listed for GV400 vertical shaft engines, H3011 riding mowers, and H3013 riding mowers; confirm your serial number against the fitment table to select the right part
- Axial Control — a correctly fitted thrust washer limits end-play and prevents the unwanted axial movement that causes premature wear on adjacent rotating components
A thrust washer is a thin, flat bearing surface positioned between rotating or sliding components to control axial (end-to-end) movement and absorb thrust loads. In vertical shaft engines and riding mower drivetrains, it sits between moving parts to limit end-play and reduce metal-to-metal contact along the shaft axis. When a thrust washer wears thin or is missing entirely, the shaft can shift axially under load, accelerating wear on the components it bears against and leading to noise, vibration, and eventual mechanical failure.
