SADEV 54-Tooth Crownwheel (15-Shaft) F1908252 - ST75 Sequential Gearbox

The SADEV 54-Tooth Crownwheel: Do Not Sacrifice the Precision of Your ST75 Transmission

The final drive is the heart of your sports vehicle's drivetrain. If you drive a Renault Clio 3 Cup equipped with the SADEV ST75 sequential gearbox, every tooth counts. The 54-tooth crownwheel, in constant mesh with the 15-tooth secondary shaft, must be flawless. Using a worn or non-compliant crownwheel exposes you to serious reliability risks.

The Risks Incurred Without a Genuine SADEV Part:

Loss of Meshing Integrity and Premature Failure

A SADEV 54-tooth crownwheel (reference F1908252) must have perfect geometry. If it is worn, you lose the optimal contact surface with the pinion shaft, generating hot spots and localized stresses. The risk of tooth shearing and complete final drive failure is real, leading to a costly immobilization of your Clio 3 X85 Cup.

Accelerated Degradation of the Drive Pinion (15-Tooth Secondary Shaft)

Wear on the crownwheel acts as an abrasive on the opposing pinion. You lose the lifespan of the 15-tooth secondary shaft and adjacent bearings. The cost of a repair becomes exponential. Only a genuine SADEV crownwheel guarantees the longevity of your entire ST75 transmission.
