The Honda 90751-VG3-000 Woodruff Key (3/16X5/8) is a genuine OEM component designed for Honda walk-behind lawn mowers including the HRB216, HRB217, HRC216, HRN216, HRR216, HRS216, HRT216, HRX217, and HRZ216. As a direct Honda OEM part, it is manufactured to the same specifications as the original, ensuring correct fit within the drivetrain of your mower. Always confirm fitment by checking your mower's model and serial number against the compatibility table before ordering.
Key Features
- Genuine Honda OEM Part — sourced directly from Honda, this Woodruff Key (3/16X5/8) meets the original design intent for the mowers it was built for, with no guesswork on sizing or geometry.
- Exact 3/16 x 5/8 Dimensions — the specific size designation is the critical match point; verify your existing key's dimensions before installation to confirm this listing applies to your unit.
- Wide Mower Compatibility — listed for Honda HRB216, HRB217, HRC216, HRN216, HRR216, HRS216, HRT216, HRX217, and HRZ216 lawn mowers; confirm your model and serial number against the fitment table.
- Shaft-to-Component Alignment — a correctly fitted Woodruff Key locks rotational alignment between a shaft and its mating component; a worn or sheared key allows slippage that disrupts power transfer and can cause further drivetrain damage.
A Woodruff Key is a small, semi-circular metal key that seats into a matching slot — called a keyway — cut into both a rotating shaft and the hub of the component mounted to it, such as a blade adapter, pulley, or flywheel. Its purpose is to prevent the mounted component from rotating independently of the shaft, ensuring power is transferred correctly. When a Woodruff Key shears or wears, the shaft and the component it drives lose their locked relationship, causing slippage, loss of drive, and the potential for accelerated wear to surrounding components — making prompt replacement essential to restoring normal mower operation.
