SADEV ST66 Gearbox Oil Seal Driveshaft Output – Renault Clio 2 Gr N

Failing to replace this oil seal risks catastrophic failure of your ST66 SADEV gearbox

Do you drive a Renault Clio 2 Gr N with an ST66 SADEV dog-ring gearbox? Every track day or rally stage subjects your transmission to extreme stress. Ignoring the condition of a simple gearbox oil seal on the driveshaft output is playing with fire. Without a perfect new oil seal (P/N: 0205047), you expose yourself to insidious, yet devastating, transmission fluid leaks.

What Will You Lose Without This New SADEV Oil Seal?

• The Integrity of Your Gearbox: The loss of Red Line oil (or other competition oil) leads to insufficient lubrication, causing the gears and bearings of your expensive ST66 SADEV gearbox to seize. This is the risk of a complete gearbox failure.
• Your Competition Performance: A major leak can dirty your engine bay, or worse, contaminate your brakes, causing you to lose control and forcing you to retire.
• Your Time and Budget: The cost of a new oil seal is insignificant compared to the repair costs or replacement of a damaged competition gearbox. Don't waste precious hours fixing what could have been prevented.

Your Questions, Our Answers for Maintaining Your Dog-Ring Gearbox

When should the driveshaft output oil seal be replaced?

It is imperative to replace it every time the driveshaft is disassembled, during regular maintenance of your dog-ring gearbox, or at the first signs of an oil leak at the driveshaft output. This is an essential preventative measure.

Which oil should be used after replacing the oil seal?

To ensure the longevity of your ST66 SADEV gearbox, it is crucial to use oil specifically designed for competition gearboxes. We strongly recommend Red Line oil, which you can find at the bottom of this product page (along with other complementary products).
