Where it fits / what it does
• Location: Camshaft nose, inside the timing chain housing
 Function: Meshes with the timing chain to drive the camshaft at precise phase relative to the crankshaft

Why & when to replace:
 Tooth wear or pitting, chain elongation damage, or abnormal noise
 During timing chain, tensioner, or full top-end rebuilds
 To restore correct cam timing after diagnosing erratic valve events or metal debris in the housing

Product Information
Camshaft timing gear / Drive sprocket.
This camshaft timing gear is a direct-fit replacement for the factory Porsche drive gear, it ensures accurate chain engagement, quiet operation, and long-term reliability. 
Fits: Left or Right, Sold each.

Fits:
Porsche 911 1965 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998

Diagram ref no 22.

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.

About Camshaft gears / sprockets and fixings

Camshaft Gears, Sprockets & Fixings – Precision Timing Components for Porsche Engines

Camshaft gears, sprockets, and fixings are essential parts of your Porsche’s timing system. They synchronise the rotation of the camshaft and crankshaft, ensuring valves open and close precisely in tune with piston movement. This precision directly affects engine efficiency, performance, and smoothness.

At Design911, we supply a comprehensive range of genuine and high-quality camshaft gears, sprockets, and fixings for various Porsche models including 924, 944, 928 ,911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each part is precision-engineered for exact timing accuracy, strength, and durability — ensuring optimal engine operation across all driving conditions.

What Do Camshaft Gears, Sprockets & Fixings Do?

These components form the backbone of your Porsche’s valve timing system, controlling the engine’s breathing process. Their functions include:

  • Transferring rotational force from the crankshaft to the camshaft.
  • Maintaining correct valve timing for efficient combustion and power output.
  • Supporting smooth engine operation by synchronising valve and piston movement.
  • Reducing friction and wear through precision gear alignment and secure fixings.

High-quality timing components are vital for maintaining Porsche’s signature performance and engine reliability.

Why Do Camshaft Gears, Sprockets & Fixings Fail?

Over time, these parts experience constant mechanical stress, heat, and vibration. When worn or damaged, they can cause serious timing issues and potential engine failure. Common causes of failure include:

  • Tooth wear or chipping on gears and sprockets.
  • Corrosion due to oil contamination or moisture.
  • Misalignment from improper installation or worn tensioners.
  • Loose or stripped fixings affecting camshaft timing stability.
  • Age-related metal fatigue under prolonged use or performance driving.

Symptoms of worn components include engine noise (rattling or ticking), timing irregularities, loss of power, or check engine light warnings.

Why Replace Worn Timing Components?

Replacing damaged or worn camshaft gears, sprockets, and fixings ensures your Porsche’s engine maintains precise timing and dependable performance. Neglecting these parts can lead to timing failure — potentially resulting in serious internal engine damage.

Benefits of replacement include:

  • Restored valve timing accuracy and smooth engine operation.
  • Improved performance, torque, and throttle response.
  • Enhanced reliability and longevity of engine components.
  • Reduced risk of catastrophic engine damage.

All camshaft gears and sprockets from Design911 are crafted from high-strength steel or lightweight alloys, designed for precision meshing, minimal friction, and long-term durability under demanding driving conditions.
