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.

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

This sprocket (gear) is part of the timing / camshaft drive system, engaging with the timing chain (or drive chain) to convert crankshaft rotational motion into synchronized camshaft motion. It ensures that the camshafts open and close valves at the correct moments relative to piston position, essential for proper combustion, engine efficiency, and emissions. Accurate tooth profile, hardness, and alignment are crucial—improperly manufactured or worn sprockets can lead to timing drift, noise, chain jump, or catastrophic engine damage.
Original stock / old timing gears can wear, fatigue, or lose tooth integrity over time — especially under heat cycles and chain load. A worn or mismatched sprocket may cause timing chain noise (ticking, rattle), timing drift, or—worst case—chain jump or engine damage. An new replacement restores correct tooth geometry, material hardness, and precision alignment, ensuring the timing system operates smoothly and reliably.

Understanding OEMatch Camshaft gears, sprockets and fixings
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original camshaft gears, sprockets and fixings.
OE (Original Equipment) refers to parts matching original specifications for the camshaft gears, sprockets and fixings and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM camshaft gears, sprockets and fixings engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch supplies a wide range of Porsche parts, from gaskets to suspension hardware and engine parts, cataloguing over 4,000 part numbers and more than 8,700 OE cross-references, and continues developing new lines to support Porsche vehicles.
Benefits Include
- Restores correct valve timing and engine smoothness
- Reduces risk of internal engine damage by maintaining timing accuracy
- Offers options of materials and fixings suited to specific model requirements
Why Camshaft gears, Sprockets & Fixings Wear and Fail
- Tooth wear or chipping from prolonged use or contamination
- Corrosion due to oil contamination or moisture
- Misalignment or loose fixings caused by worn tensioners or improper installation
The Importance of Replacing with OEMatch Camshaft gears, Sprockets and Fixings
For Porsche engines, timing components play a central role in valve control and engine durability. Replacing damaged or worn camshaft gears, sprockets and fixings restores timing precision, supports consistent combustion and reduces the likelihood of costly internal damage. Choosing parts matched to the vehicle application and following correct installation procedures helps preserve engine function and reliability.
Advantages
- Direct-fit alternatives made to original-spec dimensions and tolerances
- Extensive parts catalogue and cross-references to aid model coverage
- Technical information and fitting guidance to support correct selection
