What you lose by ignoring the wear of your 4th gear wheel on the Clio 2 Gr N

The Renault Clio 2 Group N is a rallying legend, and its SADEV ST66 gearbox is engineered for excellence. If you detect abnormal noises, difficulty engaging the gear, or gear jumps under full load, it's a sign that your 4th gear wheel is suffering. Continuing to drive in this condition means risking:

An immediate retirement: A worn gear eventually yields under torque, causing the total breakage of the gear train and a forced stop of your rally or circuit race.
A loss of performance: Even without failure, tired or eroded teeth create excessive friction, leading to a loss of power and overheating of the gearbox oil.
Amplified repair costs: A failure of this 4th gear wheel (26 teeth), reference F1903207, can damage the opposing pinion and the shaft, multiplying the repair price.

FAQ: Pinion Replacement on SADEV ST66 Gearbox

Should I replace the 4th gear pinion (23 teeth) at the same time as the wheel (26 teeth)?

It is strongly recommended to replace both elements of the ratio (wheel and pinion) simultaneously. Even if the pinion (23 teeth) looks visually correct, it will have suffered the same fatigue and type of wear as the wheel (26 teeth). Installing a new part on an old part reduces the lifespan of the assembly and compromises the reliability of the ratio. The 4th gear pinion is available as a complement at the bottom of this page.

Can I install this part myself?

Replacing a gear wheel on a SADEV sequential gearbox is a precision mechanics operation that requires specific tools, an ultra-clean environment, and knowledge of center distance and pre-tension adjustment. For the reliability and performance of your Clio 2 race car, we advise you to entrust this task to our specialized technicians in our workshops near Lille or to send us the gearbox for a complete reconditioning.
