Honda B/D/F/H Series Camshaft Key – OEM Cam Gear Alignment Key
The Honda B/D/F/H Series Camshaft Key (Part Number: 90741-657-000) is the small chunk of metal that keeps your cam timing honest. This genuine Honda camshaft key locks the cam gear to the camshaft so the gear can’t walk, slip, or shift under load. If you’re doing a timing belt, cam swap, or full build on a B, D, F, or H, this is the OEM Honda camshaft key that keeps your Honda cam timing keyway exactly where it should be. These keys are commonly referred to as a Woodruff Key as well.
This genuine Honda cam gear alignment key is made to factory spec, so the fit on both the cam and gear is tight and repeatable. It’s the correct B series camshaft key OEM replacement, and also works on select D Series, F and H Series. Use it for engine rebuilds, cam upgrades, Acura camshaft key replacement, or anytime you find a rounded or mangled key. Sticking with a Genuine Honda camshaft key helps keep factory timing accuracy and long-term valvetrain reliability, instead of trusting a mystery key that could shear and take valves with it.
