Contitech CT1120 Timing Belt

Contitech CT1120 Timing Belt – Precision Power Transmission

The Contitech CT1120 Timing Belt is engineered for high‑performance internal combustion engines that demand reliable, silent operation and precise timing. Designed with a 25.9 mm width and 141 teeth, this belt delivers consistent torque transfer while minimizing wear on critical engine components.

Key Technical Specifications

• Width: 25.9 mm – optimal for medium‑to‑large displacement engines.
• Teeth Count: 141 – ensures accurate synchronization between camshaft and crankshaft.
Material Composition: Premium reinforced rubber with a durable polyurethane coating, providing excellent resistance to heat, oil, and abrasion.
• Application Range: Engine displacements from 2.5 L to 3.0 L, commonly found in commercial vans and light trucks.

Engine Compatibility

The CT1120 is specifically tailored for the Volkswagen Crafter series, including:

• Crafter 30‑50 Van (2E) – 2.5 TDI engines.
• Crafters 30‑35 Bus (2E) – suitable for both passenger and cargo configurations.
• Crafters 30‑50 Pritsche/Fahrgestell (2F) – heavy‑duty chassis variants.

Engineers have verified that the belt’s tooth profile matches the camshaft gear geometry of these models, guaranteeing seamless operation across all operating conditions.

Design Features for Longevity

• High‑Temperature Resistance: The polyurethane coating maintains flexibility up to 120 °C, preventing brittleness in hot engine environments.
• Oil & Fuel Protection: Integrated anti‑oil leakage design reduces the risk of belt contamination and extends service life.
• Noise Reduction: Smooth tooth engagement minimizes vibration, resulting in quieter engine performance.

Installation Guidelines

1. Remove the old timing belt carefully, noting the alignment marks on the camshaft and crankshaft gears.
2. Inspect all related components (pulleys, tensioners, idlers) for wear or damage before installing the new CT1120.
3. Position the new belt around the pulleys, ensuring that the teeth engage correctly with each gear tooth.
4. Tighten the tensioner to the manufacturer’s specified torque setting.
5. Re‑check alignment marks and perform a manual rotation test to confirm proper timing.

Performance Benefits

Choosing the Contitech CT1120 Timing Belt delivers:

• Enhanced Engine Efficiency: Precise timing reduces combustion losses and improves fuel economy.
• Reduced Maintenance Costs: Longer service intervals mean fewer replacements over the vehicle’s lifespan.
• Improved Reliability: Consistent belt performance under varying loads ensures dependable operation for commercial fleets.
