SADEV Countershaft Shim ST66 - Renault Clio 2 Gr N

The Cost of Poor Shimming: Avoid Premature Failure of Your SADEV Countershaft

The countershaft shim (Ref. F1903028) is much more than a simple spacer; it is a shimming piece that determines the optimal axial play of the countershaft in the casing of your SADEV ST66 sequential gearbox. Using a non-compliant or overly worn shim means risking losing the precise adjustment necessary for reliability.

What You Lose by Neglecting Shimming

Incorrect axial play, even minimal, due to a degraded or unsuitable shim, results in poor positioning of the countershaft bearing. You lose the load capacity of the bearing, causing overheating, abnormal noise, and, inevitably, the destruction of the bearing. This failure can lead to gear set misalignment, shaft breakage, and the total immobilization of your Renault Clio 2 Gr N during a competition event. The precision of the F1903028 shim is the only guarantee against these costly damages.

“Should I change this shim during every SADEV gearbox service?”

The SADEV countershaft shim must be systematically inspected and replaced if it shows signs of deformation or wear. When replacing the bearing or changing the casing, the use of the F1903028 reference and adherence to mounting tolerances are crucial for transmission longevity.
