The SADEV 17-Tooth Secondary Shaft (references F9001002 / 0109001002) is the drive pinion for the 17/55 final drive ratio in your SADEV ST75 sequential gearbox. This piece is vital for transmitting engine power to the 55-tooth crownwheel and is homologated for the Renault Clio 2 X65 Cup. OPTIMIZ ACCESS is a SADEV distributor for Renault Sport vehicles (Clio 2 Gr N, Clio 2 Cup, Clio 3 Cup, Megane N4, Twingo R2). For a complete and reliable reassembly, the associated 55-tooth crownwheel is available in complementary products at the bottom of this page.
The 17-tooth secondary shaft is subjected to considerable torsional stress in your SADEV ST75 sequential gearbox of the Renault Clio 2 Cup. This is not a part to neglect. A worn shaft or one showing the beginning of a micro-crack exposes you to a major risk: you lose the robustness of the transmission and jeopardize your entire differential and gearbox assembly.
A defect on the secondary shaft F9001002 compromises the meshing with the crownwheel. You lose transmission efficiency, generating friction and excessive heat. The most costly scenario is the rupture of the pinion teeth, leading to the complete failure of the final drive in your Clio 2 X65 Cup. This results in vehicle immobilization and major repair costs.
Play or misalignment caused by a fatigued secondary shaft increases operating temperature. You lose the quality of lubrication, which accelerates the wear of all bearings and other pinions in your SADEV sequential gearbox. Only a genuine SADEV part ensures the maintenance of competition tolerances.
