Information
Camshaft chain sprocket.
Camshaft timing chain sprocket engages with the timing chain to drive the camshaft at the correct speed relative to the crankshaft. It is precisely manufactured to replicate the original sprocket’s profile, tooth count, and material properties so that it performs and fits like the genuine factory part.
Fits:
Porsche 911 1965 - 1989
Diagram ref no 6.
The camshaft chain sprocket works in conjunction with the timing chain and crankshaft sprocket to ensure the camshaft and crankshaft remain correctly synchronised. This synchronisation is crucial for precise valve timing - determining when intake and exhaust valves open and close relative to piston position. Proper timing is essential for efficient combustion, smooth engine performance, and long-term reliability.
The timing chain system is one of the most critical mechanical systems in an internal combustion engine. The sprockets that guide and drive the chain can wear or suffer surface fatigue, which may lead to:
• Timing chain slack or noise
• Inaccurate valve timing
• Engine roughness or power loss
• Increased wear on tensioners and guides.
Worn sprocket teeth can accelerate chain wear and compromise the whole timing train. Replacing the camshaft sprocket restores optimal fit, timing accuracy, and helps protect associated timing components - especially vital on high-mileage or restored classic engines.
Replace the camshaft chain sprocket if you notice:
• Noticeable timing chain noise (rattle at start or idle)
• Timing chain slack or visible elongation
• During full timing chain/tensioner overhaul
• Wear or damage on original sprocket teeth
• Engine running irregularly or rough at idle
