The Honda 90766-VE4-003 Square Key (1/4"x1/4"x1") is a genuine OEM component designed for Honda CD7036, CD7048, CD7052, CD7060, HRC7013, HRC7018, and HRC7020 commercial mowers. As a direct Honda OEM part, this square key is manufactured to the exact dimensions required for proper drive engagement on these machines. Confirm the part number 90766-VE4-003 against your machine's serial number using the fitment table before ordering, as Honda supersedes hardware parts at serial breaks.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this square key meets the exact dimensional specifications required for correct drive coupling on Honda commercial mowers.
- Exact 1/4" x 1/4" x 1" Profile — the precise cross-section and length ensure full key engagement between the shaft and mating component, maintaining positive torque transfer without slop or movement.
- Broad Commercial Mower Fitment — listed for the CD7036, CD7048, CD7052, CD7060, HRC7013, HRC7018, and HRC7020; verify your serial number against the fitment table to confirm the correct part for your unit.
- Drive Integrity — a worn or damaged square key allows the driven component to slip on the shaft, resulting in lost drive and potential damage to the shaft or hub; replacing it promptly restores full power transmission.
A square key is a small rectangular drive component that seats in matching keyways machined into both a shaft and the hub of a driven component — such as a blade clutch, pulley, or sprocket — locking them together rotationally so torque transfers from the shaft to the driven part without slippage. On Honda commercial mowers, this connection is essential to consistent blade or drive performance. When the key shears, deforms, or works loose in its keyway, the driven component can spin independently of the shaft, causing a complete loss of function at that drive point and risking damage to the surrounding hardware.
