The Honda 90451-KG4-000 Thrust Washer (22X39X2) is a genuine OEM replacement designed for H6522 compact tractors and HP250 and HP400 power carriers. As a direct Honda OEM component, this washer is built to the exact dimensional specification — 22 mm inner diameter, 39 mm outer diameter, 2 mm thickness — ensuring the correct fit and function Honda engineering requires. Verify your machine's serial number against the fitment table before ordering, as Honda periodically supersedes parts at serial number breaks.
Key Features
- Genuine OEM Dimensional Accuracy — sourced directly from Honda, this thrust washer meets the exact 22×39×2 mm specification, ensuring it seats correctly and controls axial load as intended in the original design.
- Direct OEM Replacement — drops in as a like-for-like replacement with no modification needed to restore correct drivetrain function to H6522 compact tractors and HP250 and HP400 power carriers.
- Serial Number Verification Recommended — Honda supersedes components at specific serial breaks; confirm your machine's serial number against the fitment table to ensure part number 90451-KG4-000 is the correct listing for your unit.
A thrust washer controls axial movement between two rotating or sliding components, absorbing the loads that push along the axis of a shaft rather than across it. In compact tractors and power carriers, this type of washer is placed at key points in the drivetrain or transmission assembly to maintain correct spacing and prevent metal-to-metal contact under load. When a thrust washer wears thin or fails, the components it separates can shift out of position, leading to increased wear, noise, or loss of smooth operation in the drivetrain.
