SACHS 2294 001 921 Flywheel Dual-mass flywheel For Citroen C4 GRAND PICASSO I

SACHS 2294 001 921 Flywheel Dual‑Mass Flywheel

The SACHs 2294 001 921 is a high‑performance dual‑mass flywheel (DMF) engineered for the Citroën C4 Grand Picasso and related models. Designed to replace the original OEM component, it delivers superior vibration damping, smoother power delivery, and enhanced durability under demanding driving conditions.

Key Features

• Dual‑Mass Design: Combines two separate masses linked by a flexible coupling to absorb engine vibrations and reduce drivetrain noise.
• Precision Machining: Manufactured with tight tolerances to ensure perfect alignment with the clutch assembly and transmission input shaft.
• High‑Grade Materials: Constructed from premium alloy steel, providing excellent strength-to-weight ratio and resistance to fatigue.
• Optimized Geometry: Engineered for optimal torque transfer while maintaining low rotational inertia, improving acceleration response.
• Compatibility: Specifically calibrated for Citroën C4 Grand Picasso (Mk1) models equipped with the 2.0 L HDI engine, covering production years 2006‑2013.

Technical Specifications

Installation Highlights

The SACHs 2294 001 921 is engineered for a straightforward replacement process. Key installation steps include:

1. Remove the existing flywheel and clutch assembly.
2. Align the new DMF with the transmission input shaft, ensuring proper torque arm positioning.
3. Screw in the mounting bolts to the specified torque sequence (typically 80 Nm followed by a 90° lock).
4. Reinstall the clutch disc and pressure plate, then reassemble the hydraulic system.
5. Perform a final alignment check and conduct a test drive to verify smooth operation.

Performance Benefits

• Smoother Ride: The dual‑mass construction significantly reduces engine vibration transmission, resulting in a quieter cabin experience.
• Improved Acceleration: Lower rotational inertia allows the engine to rev more freely, enhancing throttle response.
• Extended Longevity: High‑quality materials and precise engineering reduce wear on clutch components, extending overall drivetrain life.
• Enhanced Fuel Efficiency: By minimizing energy loss through vibrations, the DMF contributes to marginal gains in fuel economy.

Quality Assurance

The SACHs 2294 001 921 undergoes rigorous testing at every stage of production. Each unit is inspected for dimensional accuracy, surface finish, and mechanical integrity before leaving the factory. This commitment to quality ensures that customers receive a component that meets or exceeds OEM standards.

Applications Beyond Citroën C4 Grand Picasso

While primarily designed for the Citroën C4 Grand Picasso Mk1 (2.0 L HDI), this flywheel is also compatible with several other vehicles sharing similar drivetrain configurations, including certain Peugeot and Citroën MPV models from the same era.

Conclusion

The SACHs 2294 001 921 Flywheel Dual‑Mass Flywheel represents a blend of engineering excellence and practical performance. Its meticulous design, superior materials, and proven compatibility make it an ideal choice for owners seeking to restore or enhance the driving dynamics of their Citroën C4 Grand Picasso.
