Loss of Traction: SADEV Left Drive Flange F1903157 for Clio 2 Gr N ST66 Gearbox
The Left Drive Flange (also known as the Gearbox Output Cup) is the interface that absorbs and transmits the shocks and torque from your SADEV ST66 gearbox to the left wheel. If this part is worn or cracked, you don't just lose a component; you lose your vehicle's ability to transmit power to the ground. This original SADEV part (Ref. 7711129607) is intended exclusively for the Renault Clio 2 Gr N.
What You Risk with a Defective Drive Flange:
- ❌ Immediate Rupture: Under the effect of torsional forces during acceleration, a fatigued drive flange can **snap completely**, leading to the immediate stopping of your Clio 2 Gr N and potential damage to the gearbox casing.
- ❌ Leaks and Contamination: Excessive play or a poor interface with the gearbox output oil seal can cause a **massive oil leak**, contaminating the environment and leading to overheating and internal destruction of the SADEV gearbox.
- ❌ Damage to Internal Components: Abnormal vibrations or misalignment transmitted by a worn drive flange cause premature wear to internal transmission elements (differential, gears). The reliability of the entire assembly is compromised.
Original SADEV Part: Optimal Torque Transmission
The SADEV Drive Flange F1903157 is manufactured from high-strength treated steel, designed to integrate perfectly with the ST66 gearboxes equipping Renault Sport vehicles. It ensures the protection of the driveshaft joint components (grease, boot, tripod, ntn spring, cup spring) housed within it.
