Main casing equipped SADEV / Renault Clio 2 CUP / ST75-14

Product introduction

This SADEV breather fitting is a new part intended for SADEV ST75-14 sequential gearboxes fitted to Renault Clio 2 CUP cars. Designed for motorsport use, it ensures correct transmission ventilation under demanding operating conditions.

Role of the part

The breather fitting allows the gearbox to compensate for internal pressure changes generated by rising oil temperature and rotating mechanical components. It helps prevent excess pressure in the gearbox casing, thereby limiting the risk of oil leaking through gaskets, oil seals or mating faces.

Symptoms or consequences of a worn or faulty part

• Oil seepage or leaks around the gearbox.
• Excess internal pressure that may place premature strain on seals.
• A blocked, damaged or missing breather after dismantling.
• Risk of contamination of the engine bay or transmission area by sprayed oil.
• Suboptimal gearbox operation during intensive use on track or in competition.

Benefits of replacement

• Restores correct ventilation of the SADEV sequential gearbox.
• Contributes to transmission reliability under motorsport conditions.
• Reduces the risk of leaks caused by excessive internal pressure.
• Allows clean reassembly during gearbox overhaul or refurbishment.
• A part suited to the requirements of Renault Sport vehicles used in competition.
