SADEV 2-3 Speed Stepped Thrust Washer ST66 - Renault Clio 2 Gr N

Why Not Replacing the 2nd-3rd Stepped Thrust Washer Risks Premature Failure of Your SADEV Gearbox

The 2nd-3rd gear stepped thrust washer (Ref. F1903017) is a fundamental part ensuring the correct positioning of the 2nd and 3rd gear wheels and managing the axial thrust forces. In case of wear on this original SADEV washer, you introduce play that is directly transmitted to the needle cages and dog teeth.

???? Performance Loss and Risk of Chain Damage

Failing to change this washer during an overhaul means risking rapid degradation of adjacent components. Excessive axial play leads to poor lubrication, overheating, and, crucially, irregular wear of the gear wheels. You lose the performance of your gearbox and expose yourself to a potentially destructive gear jump-out between these crucial ratios on your Renault Clio 2 Gr N. Saving money on this small part results in a major financial loss and a race retirement.

“Is the F1903017 stepped thrust washer interchangeable with other models?”

This part is an Original SADEV part designed specifically for the ST66 gearbox and Renault Sport competition applications (Clio 2 Gr N, Clio Cup...). Using a non-compliant or worn part is a major gamble on the lifespan of your transmission. Purchase authenticity from Optimiz Access.
