Contitech Timing Belt CT798

Contitech Timing Belt CT798

The Contitech Timing Belt CT798 is a high‑performance camshaft–crankshaft synchronisation component designed for precision engines, particularly those found in classic Porsche models such as the 944 and 968 series. Its construction incorporates advanced materials and engineering to deliver reliable operation under demanding conditions.

Key Features & Technical Specifications

• Teeth Count: 119 teeth – engineered for optimal engagement with both camshaft and crankshaft gear sets.
• Material Composition: Premium reinforced rubber core with a durable polyurethane outer layer, providing excellent resistance to heat, oil, and wear.
• Width & Thickness: Standard dimensions compatible with OEM specifications for the target engine families.
• Load Capacity: Designed to handle high torque outputs typical of 2.5L–3.0L inline‑four engines.
• Durability: Factory‑tested life expectancy exceeding 100,000 miles under normal operating conditions.

Application & Compatibility

The CT798 is specifically engineered for the following Porsche engine models:

• Porsche 944 (1988–1991) – both coupe and convertible variants.
• Porsche 968 Convertible – 2.5L and 3.0L configurations.
• Other inline‑four engines that match the original timing belt specifications for camshaft and crankshaft gear ratios.

Its design ensures a perfect fit with OEM pulleys, tensioners, and idler gears, maintaining precise timing intervals critical for engine performance and longevity.

Installation & Maintenance Guidelines

1. Preparation: Warm the engine to operating temperature before removal to reduce belt stiffness. Disconnect battery terminals to prevent accidental starter engagement.
2. Belt Removal: Release tension using the factory‑specified method (tensioner lever or hydraulic system). Carefully unwind the belt from both camshaft and crankshaft pulleys, noting the direction of rotation for reassembly.
3. Inspection: Check the new CT798 for any visible defects such as cracks, fraying, or uneven wear. Verify that the teeth are intact and properly aligned.
4. Tension Adjustment: Reinstall the belt following the manufacturer’s tension specifications. Use a calibrated tension gauge to ensure optimal preload.
5. Reassembly: Align all pulleys accurately, re‑engage the timing marks, and reconnect the battery.
6. Post‑Installation Check: Start the engine and listen for any abnormal noises. Verify that the engine runs smoothly and that all timing indicators are correct.

Performance Benefits

• Enhanced Engine Timing Accuracy: Precise tooth engagement reduces timing drift, improving combustion efficiency and power output.
• Reduced Noise & Vibration: The reinforced construction dampens belt flex, resulting in quieter operation.
• Long‑Term Reliability: High‑grade materials resist oil degradation and thermal expansion, extending service life.
• Compatibility with OEM Tensioners: Works seamlessly with factory tensioning systems, eliminating the need for aftermarket adapters.
