SADEV ST75 Gearbox Potentiometer Renault Clio 3 X85 Cup Ref. 0101908100

The Risk of a Faulty Part: What You Lose Without a Reliable SADEV Potentiometer

The Renault Clio 3 Cup (project code X85) is a race thoroughbred, equipped with a SADEV ST75 sequential gearbox. This system relies entirely on the precision of its sensors. If the gear position potentiometer starts to send incorrect signals, you immediately suffer inappropriate engine cuts or, worse, the absence of cut during fast upshifts. This can not only make you lose several seconds per lap but also jeopardize the reliability and lifespan of your high-end SADEV transmission. Do not let a small component compromise your entire F4R engine.

SADEV Gear Potentiometer: Authenticity for the Clio Cup

Installing a quality part and genuine component is vital for race cars like the Clio Cup. The potentiometer (Ref. 0101908100 / F1908100) is manufactured by SADEV, the very designer of the ST75 gearbox. This product guarantees perfect compatibility and a surgically precise reading of the engaged gear. You avoid calibration problems and ensure the proper functioning of your electronic engine management and data acquisition system.

Critical Application: Sequential Gearbox and Shifter

This position sensor is the interface between the gearbox mechanics and your Renault Sport's electronics. It is essential for:

• Managing the shifter and ignition cut during full-throttle gear changes.
• Accurate display of the gear ratio on the dashboard or racing display.
• Reliable data acquisition for analyzing your performance in motorsports.

FAQ: SADEV Gearbox Potentiometer Maintenance

How often should the SADEV potentiometer be replaced?

The potentiometer is a wear part in competition, sensitive to vibrations and temperature variations. There is no fixed mileage, but it is recommended to replace it preventatively or at the first signs of failure (unstable reading, erratic engine cuts). Do not let your performance depend on a tired sensor.

This reference is specifically adapted to the SADEV ST75 gearbox of the Renault Clio 3 X85 Cup. Although the systems are similar, it is crucial to always check compatibility with your exact model to avoid mounting errors on your Clio 2 X65 Cup or other sequential transmission. In case of doubt, our technical service is available.

Can I install it myself or should I use a specialist?

Replacing the gearbox potentiometer is a delicate operation that directly impacts electronic management. We strongly recommend entrusting the installation to a specialist in SADEV sequential gearboxes or to our experts at our workshops in the **Hauts-de-France** region (**Lille**, **Douai**, **Valenciennes**). A calibration check is essential after fitting.
