Engine Variable Valve Timing (VVT) Sprocket
Engine Variable Valve Timing (VVT) Sprocket from Evergreen
An engine variable valve timing (VVT) sprocket, also called a cam phaser, rotates the camshaft relative to the timing chain or belt. Worn phasers often knock on startup.
When to Replace
- Knocking or rattling from the phaser on startup
- Camshaft timing codes
- Phaser that will not hold position
Installation Tips
- Lock the camshaft and phaser as directed
- Replace the cam bolt if specified
- Consider timing chain components at the same time
