Sachs 2294 001 995 - Flywheel

Sachs Dual‑Mass Flywheel (Part No. 2294 001 995)

The Sachs 2294 001 995 is a high‑performance dual‑mass flywheel designed for modern front‑engine, front‑drive vehicles that employ a manual or automated manual transmission. It is engineered to provide smooth power delivery, reduce vibration and noise, and improve overall drivetrain efficiency.

Key Design Features

• Dual‑Mass Construction: Combines two separate masses connected by a torsional damper system. This configuration absorbs engine torque spikes and dampens vibrations before they reach the transmission.
• Optimized Torsional Stiffness: The flywheel’s internal geometry is tailored to match the specific torque curve of compatible engines, ensuring optimal performance across the entire rev range.
• High‑Strength Alloy: Manufactured from a lightweight yet durable alloy that balances weight reduction with structural integrity, contributing to better fuel economy and handling dynamics.
• Precision Machining: Tight tolerances in the mounting interface guarantee a secure fit on the crankshaft, minimizing play and extending component life.
• Integrated Bearing Interface: Designed for seamless integration with the vehicle’s bearing system, reducing maintenance requirements and ensuring long‑term reliability.

Compatibility Overview

The flywheel is specifically engineered for a range of popular European models. Below is an extensive list of vehicles that accept the Sachs 2294 001 995, grouped by manufacturer and model family:

• Peugeot: 208 (1.2 THP), 308, 2008, DS3, DS, Partner, Vauxhall Crossland X/P, Citroën C3, C4, Berlingo Multispace.
• Citroën: DS, DS3, C3, C4, Berlingo Multispace, Berlingo B9, C3 Aircross, C3 Picasso, C3 II.
• Opel: Vauxhall Crossland X/P, Partner, Vectra, Astra, Corsa, Mokka, Zafira.
• Vauxhall: Crossland X/P, Partner, Vectra, Corsa, Mokka.

All models listed above share a common engine‑transmission architecture that requires a dual‑mass flywheel of the specified dimensions (approximately 228 mm bore). The part is compatible with both manual and automated manual gearboxes that use the standard Sachs 9805958180 or 9677247180 transmission housings.

Installation Highlights

Installing the Sachs 2294 001 995 involves a straightforward replacement of the existing flywheel. Key steps include:

1. Removal of Old Flywheel: Detach the crankshaft pulley, remove the old flywheel using a flywheel puller or impact driver, and clean the mounting surface.
2. Preparation of New Flywheel: Inspect for damage, apply anti‑seize compound to the bearing interface, and ensure the flywheel is free from burrs.
3. Torque Specification: Tighten the flywheel bolt to the manufacturer’s specified torque (typically around 200 Nm) using a calibrated torque wrench. This step is critical for maintaining alignment and preventing premature wear.
4. Re‑assembly of Drivetrain: Reinstall the crankshaft pulley, reattach the clutch or torque converter as applicable, and reconnect all ancillary components (e.g., driveshaft, transmission input shaft).

After installation, a short test drive is recommended to verify smooth operation and confirm that vibration levels are within acceptable limits.

Performance Benefits

• Smoother Power Delivery: The dual‑mass design mitigates the harshness of engine torque spikes, resulting in a more refined driving experience.
• Reduced NVH (Noise, Vibration, Harshness): By damping torsional vibrations, the flywheel contributes to lower cabin noise and improved ride quality.
• Enhanced Transmission Longevity: Absorbing shock loads protects the transmission’s internal components, extending service intervals.
• Improved Fuel Efficiency: A lighter flywheel reduces rotational inertia, allowing the engine to accelerate more efficiently and lowering fuel consumption.

Maintenance Tips

While the Sachs 2294 001 995 is designed for durability, regular inspection can preempt potential issues:

• Check for signs of wear on the bearing interface and replace if necessary.
• Inspect the flywheel’s mounting surface for cracks or deformation after high‑speed operation.
• Ensure that the clutch or torque converter is properly aligned to avoid undue stress on the flywheel.

Conclusion

The Sachs Dual‑Mass Flywheel (2294 001 995) represents a blend of precision engineering, material science, and automotive heritage. Its compatibility with a wide array of European models makes it an essential component for maintaining the performance and reliability of modern front‑drive vehicles. Whether you are restoring a classic Peugeot 208 or upgrading a Citroën DS3’s drivetrain, this flywheel delivers the smoothness, durability, and efficiency that discerning drivers expect.
