SADEV Reverse Gear Washer F1903035 - Renault Clio 2 Gr N ST66 Gearbox

Avoid Engagement Problems: SADEV F1903035 Reverse Gear Washer for ST66 Gearbox

In competition mechanics, even the smallest parts are crucial. If the reverse gear washer in your SADEV ST66 gearbox is worn, you are not just losing a simple part; you are losing the guarantee of a clean engagement of reverse gear in your Renault Clio 2 Gr N.

Direct Consequences of a Worn Reverse Gear Washer:

• ❌ Engagement Difficulty: Wear causes excessive play, making reverse gear engagement (often critical in rallying) difficult or impossible at the crucial moment.
• ❌ Premature Wear: The washer acts as a thrust surface. If it is out of tolerance, it generates abnormal friction and accelerated wear of the reverse gear bearing F0056015 and the pinions.
• ❌ Compromised Reliability: A defective part affects the integrity of the entire transmission, risking damage to more expensive components such as the shaft or forks (requiring the fork circlip 0601002 in addition).
