SADEV Reverse Shift Fork Circlip ST66 Gearbox – Clio 2 Gr N

A worn circlip = inability to maneuver your Clio 2 Gr N in critical situations

In motorsport, reverse gear is often overlooked, but it can be vital for getting out of a tricky situation on stage or maneuvering in the service park. In your Renault Clio 2 Gr N, the SADEV reverse gear shift fork circlip (P/N: 0601002) is the guarantor of this function. Using a tired or deformed circlip during an overhaul means taking the risk of it failing.

The Risks Associated with a Shift Fork Circlip Failure

• Total Loss of Reverse Gear: If the circlip fails, the shift fork is no longer retained, making reverse gear engagement impossible. You lose the ability to quickly get out of trouble, which can cost you precious time in the race.
• Damage to the Bearing Support and Washer: The lack of shift fork retention causes play and premature wear on adjacent components, including the reverse gear bearing support and the reverse gear washer. The repair cost increases unnecessarily.
• Compromised Overall Reliability: This circlip, although small, is essential to the proper kinematics of the ST66 dog-ring gearbox. Its failure introduces a weakness into the entire transmission.

Questions about the Reliability of your Reverse Gear Shift Fork

Can I reuse the old circlip during an overhaul?

No. It is strongly discouraged to reuse a circlip, as it may have undergone plastic deformation during disassembly or be fatigued by stress cycles. Replacing this part with a new one (P/N: 0601002) is insurance against future problems.

Which parts should be checked at the same time?

When replacing this circlip, it is wise to inspect the condition of the associated reverse gear washer and reverse gear bearing support. You can find these complementary products at the bottom of this page.
