Contitech CT879 Timing Belt

Contitech CT879 Timing Belt

The Contitech CT879 Timing Belt is a high‑performance, OEM‑grade component designed to synchronize the camshaft and crankshaft in a wide range of Fiat and Lancia engines. With its precise tooth geometry and durable construction, it delivers reliable timing under demanding operating conditions.

Key Technical Features

• Width: 25 mm – the optimal dimension for many compact engine bays.
• Number of Teeth: 158 – engineered to match the cam‑shaft profile of 1.6 L, 16‑valve engines.
• Material Composition: High‑grade rubber reinforced with a proprietary blend of fibers and additives that resist heat, oil, and wear.
• Cam‑shaft Profile Compatibility: Designed for the standard cam‑shaft geometry used in Fiat Brava, Bravo, Doblo, Marea, Multipla, Palio, Stilo, Lancia Delta II, Lybra, and other models.
• Crankshaft Compatibility: Matches the crankshaft tooth pattern of the same engine families, ensuring perfect synchronization.

Performance Benefits

The CT879 offers several advantages over generic timing belts:

• Enhanced Durability: The reinforced rubber matrix resists cracking and elongation, extending service life beyond typical aftermarket alternatives.
• Accurate Timing: Precise tooth alignment guarantees that valve events occur at the correct engine cycle, preserving performance and fuel efficiency.
• Reduced Noise: The belt’s construction minimizes vibration transmission to the engine block, resulting in a quieter operation.
• Easy Installation: Designed with standard tensioner mounts, it can be installed using conventional tools without special adapters.

Installation Notes

When installing the CT879, follow these essential steps to ensure optimal performance:

1. Remove the Old Belt: Carefully unwind and remove the existing timing belt, noting the position of all pulleys.
2. Inspect Components: Check the cam‑shaft and crankshaft teeth for wear or damage. Replace any damaged components before installing the new belt.
3. Align Markings: The CT879 features alignment marks on both ends of the belt. Match these with the corresponding marks on the engine housing to guarantee correct positioning.
4. Tensioner Adjustment: Use a torque wrench or manufacturer‑specified procedure to set the tensioner to the correct preload, preventing slippage.
5. Check Timing: After installation, rotate the crankshaft by hand until the timing marks align again. Verify that all valves open and close at the proper times.

Compatibility Overview

The CT879 is engineered for a broad spectrum of Fiat and Lancia models. Below is a concise compatibility list, grouped by vehicle family:

Quality Assurance

The Contitech CT879 is manufactured under strict quality control protocols. Each belt undergoes:

• Dimensional Inspection: Ensures width, tooth count, and alignment marks meet OEM specifications.
• Material Testing: Verifies rubber hardness, tensile strength, and resistance to oil and heat.
• Functional Test: Simulates engine operation to confirm timing accuracy and belt tension stability.

Maintenance Tips

While the CT879 is designed for longevity, regular checks can preempt potential issues:

• Visual Inspection: Look for cracks, fraying, or oil staining during routine maintenance.
• Tension Check: Verify belt tension at least once a year; adjust the tensioner as needed.
• Replace When Needed: If any signs of wear appear, replace the belt immediately to avoid engine damage.

Conclusion

The Contitech CT879 Timing Belt combines OEM precision with robust construction, making it an ideal choice for anyone seeking reliable timing performance in Fiat and Lancia engines. Its compatibility across multiple models, coupled with proven durability, ensures that your vehicle’s cam‑shaft and crankshaft remain perfectly synchronized for years of smooth operation.
