Starting at $25.95, AutoBuffy stocks 1 engine timing camshaft sprockets from Cloyes. The camshaft sprocket drives the camshaft in sync with the crankshaft, controlling valve timing. A worn, cracked, or stripped sprocket throws off that timing, leading to rough running, misfires, and potential engine damage if ignored.
The most important decision is matching the sprocket to your engine's exact configuration — tooth count, bolt pattern, and whether your engine uses a variable valve timing (VVT) system with a phaser-integrated sprocket or a fixed sprocket. Using the wrong sprocket will produce immediate timing faults. Secondary considerations are material grade and whether you need to replace the full timing kit or just the sprocket.
| Option | Best for | What you get |
|---|---|---|
| OEM-equivalent fixed sprocket | Direct replacement on engines without VVT, budget-conscious repair | Stamped or cast steel sprocket matched to original tooth count and keyway; no frills, reliable fit |
| OEM-equivalent VVT phaser sprocket | Engines with variable valve timing that need a phaser-integrated unit | Sprocket with built-in oil-actuated phaser mechanism; restores proper cam advance and retard function |
| Performance billet sprocket | High-mileage builds, track use, or engines with upgraded camshafts | CNC-machined steel or aluminum with tighter tolerances and multiple cam-timing adjustment positions |
| Timing kit (sprocket included) | High-mileage engines or any job where the chain and tensioner are already worn | Matched set of sprocket, chain, tensioner, and guides; prevents premature failure from mismatched wear |
Replacing the camshaft sprocket on a Nissan Note requires removing the timing cover, which typically means draining coolant, removing the harmonic balancer, and unbolting any accessories blocking access. Before removing the old sprocket, the crankshaft and camshaft must be locked at top dead center using the correct alignment tools to preserve timing reference points. Reassembly requires torquing the sprocket bolt to the manufacturer's specification and verifying cam timing before starting the engine.
