SADEV Anti-Rotation Shim F1903032 (1.5 - 3.75 mm) - Renault Clio 2 Gr N ST66 Gearbox

The Risk of Failure: SADEV Anti-Rotation Adjustment Shim F1903032 for ST66 Gearbox

In the harsh environment of competition, every component must perform flawlessly. The SADEV Anti-Rotation Adjustment Shim F1903032 is a critical, though small, safety element. If this shim is worn, deformed, or missing, you jeopardize the entire 5th gear cluster of your Renault Clio 2 Gr N.

The Dangers of a Faulty Anti-Rotation Shim:

• ❌ Rotation and Loosening: The absence or failure of the shim allows the 5th gear threaded insert to rotate. The ensuing loosening is rapid and leads to a catastrophic failure of the SADEV ST66 gearbox.
• ❌ Incorrect Play: If the thickness is not chosen correctly, the pinion play will not be optimal, resulting in excessive friction or poor holding power of the assembly.
• ❌ Race Termination: A failure caused by this small part will result in a certain retirement and potentially irreparable damage to the secondary shaft and casing.

Original SADEV Part: Precision Adjustment through Thickness Options

The F1903032 Shim is designed by SADEV Motorsport to perfectly integrate into the 5th gear fastening assembly. It works together with the 0301331 screw to lock the insert and neutralize any rotational force. It is fundamental to note that this shim is available in several thickness options, ranging from 1.5 mm to 3.75 mm.

Choosing the correct thickness ensures the perfect adjustment of the axial play of the assembly, thereby guaranteeing the maximum reliability of your sequential gearbox. Only an original SADEV part, with the correct calibration, allows you to maintain the manufacturer's mounting specifications.

Expert Advice: How to choose the right shim thickness?

The choice of thickness (between 1.5 mm and 3.75 mm) depends on the precise adjustment of the axial play of the shaft and the 5th gear pinion. This adjustment is technical and must be performed by a qualified professional, often using a micrometer and according to SADEV tolerances. To maintain the safety level required in rallying, it is highly recommended to replace the worn shim with a new one of the adjusted thickness.
