En Stock
The SADEV Left Side Output Flange (references F1908350 / 7711160348) is the gearbox output element that ensures the essential connection between the differential and the driveshaft (Lobro type) of your left-hand transmission. A vital part of the SADEV ST75 sequential gearbox, it is homologated for the Renault Clio 3 X85 Cup. OPTIMIZ ACCESS is a SADEV distributor for Renault Sport vehicles (Clio 2 Cup, Clio 3 Cup, Megane N4, Twingo R2). Its replacement is critical to prevent oil leakage and costly transmission failure. Complementary parts (oil seal, fixing screws) are available at the bottom of this product page.
The SADEV Left Output Flange F1908350: The Danger of a Weakened ST75 Transmission
The left gearbox output flange is the first interface between engine power and the left driving wheel of your Renault Clio 3 Cup. The left output flange F1908350 is specifically forged to withstand circuit stresses. If you continue to use a worn or damaged flange, you lose the structural integrity and sealing capability of your ST75 sequential gearbox, risking a critical failure.
The Risks Incurred by Maintaining a Defective Flange:
Accidental Gearbox Oil Drain and Damage to Internal Components
The correct seating of the gearbox output oil seal depends directly on the surface condition of the flange. If the seating is worn, you lose the sealing integrity, causing a significant **gearbox oil leak**. The subsequent lack of lubrication for the differential and final drive will lead to overheating and irreversible destruction of these expensive assemblies on your Clio 3 X85 Cup.
Misalignment and Rupture of the Lobro Driveshaft
The left output flange guarantees the precise alignment of the Lobro driveshaft. A part with play (ref. 7711160348) introduces abnormal dynamic stresses into the transmission shaft. You lose reliability under maximum acceleration, risking a sudden driveshaft rupture. This can cause major damage to the casing and potential track withdrawal.
