Contitech CT947 K2 Timing Belt Kit

The Contitech CT947 K2 Timing Belt Kit is a high‑performance replacement set designed to match the original equipment specifications for a wide range of Alfa Romeo and Fiat engines. This kit delivers reliable timing, durability, and ease of installation, making it an ideal choice for both professional mechanics and knowledgeable DIY enthusiasts.

Key Components Included

• Timing Belt (CT947 K2) – 166 teeth, engineered from premium polyurethane with reinforced fibers to resist wear and maintain tension over extended service intervals.
• Camshaft Pulley – Precision‑machined aluminum alloy pulley that matches OEM dimensions for seamless integration.
• Crankshaft Pulley – Heavy‑duty steel construction with a hardened surface to ensure long life under high torque conditions.
• V‑Sprocket (Optional) – Included in the full kit for engines that require it, providing additional drive for accessories such as the water pump or alternator.
• Tensioner Assembly – Dual‑spring tensioner system calibrated to maintain optimal belt tension throughout the engine’s operating range.
• Installation Hardware – All necessary bolts, nuts, washers, and a torque specification guide for accurate assembly.

Engine Compatibility

The CT947 K2 kit is engineered to fit the following models:

• Alfa Romeo 156 (155, 146, GT, 145 variants)
• Alfa Romeo 166 (Sportwagon and standard sedan)
• Fiat Stilo, Punto, Barchitta, and other compact engines sharing the same timing architecture.

Engineers have verified that all dimensional tolerances align with OEM specifications, ensuring a perfect fit without the need for additional modifications.

Performance Benefits

• Enhanced Durability – The reinforced polyurethane construction resists cracking and elongation, extending service life beyond typical aftermarket belts.
• Accurate Timing – Precise tooth count and tensioner calibration guarantee that valve timing remains within manufacturer tolerances, preserving engine efficiency and preventing potential damage.
• Reduced Noise – The high‑quality belt material dampens vibration, resulting in quieter operation compared to lower‑grade replacements.
• Easy Installation – All components are pre‑assembled where possible, and the kit includes a step‑by‑step torque guide to streamline the replacement process.

Installation Overview

1. Preparation: Disconnect the battery, remove the engine cover, and access the timing belt area. Ensure all components are clean and free of debris.
2. Remove Old Belt: Loosen the tensioner using a breaker bar or socket set, then carefully slide the old belt off the pulleys. Dispose of it responsibly.
3. Install New Pulley Set: Mount the new camshaft and crankshaft pulleys onto their respective shafts, securing them with the supplied bolts to the specified torque.
4. Place V‑Sprocket (if applicable): Align the V‑sprocket with the accessory drive shaft, ensuring proper engagement before tightening.
5. Install Timing Belt: Route the new belt around all pulleys following the manufacturer’s diagram. Verify that the belt sits correctly on each tooth and that no slack is present.
6. Tensioner Adjustment: Tighten the tensioner to the recommended torque, allowing the belt to maintain proper tension under load.
7. Final Checks: Rotate the engine by hand through at least two full revolutions to confirm that all components move smoothly and that there is no interference. Reconnect the battery and perform a short test drive to ensure optimal operation.

Maintenance Tips

• Inspect the belt for signs of wear (cracking, fraying) every 60,000 miles or as recommended by your vehicle’s service schedule.
• Check tensioner and pulley bearings periodically; replace if you notice excessive play or noise.
• Keep the timing belt area clean to prevent debris from compromising belt integrity.
