The component that seals your top speed! This SADEV 5th gear wheel, 22 teeth (P/N: F1903006) is the driven gear for the 5th ratio, which must mate perfectly with the 23-tooth 5th gear pinion on the secondary shaft of your Renault Clio 2 Gr N's ST66 dog-ring gearbox. Worn teeth or damaged dog rings on this wheel lead to performance loss, gear jumps under full load, and the risk of breaking the transmission.

Description
Product Details

A Weak 5th Gear Wheel = Straight-Line Failure and Maximum Danger

The 5th gear ratio is the most solicited in terms of thermal stress and rotation speed in your ST66 SADEV dog-ring gearbox. The 5th gear wheel, 22 teeth (P/N: F1903006) for the Renault Clio 2 Gr N is the part that must withstand full load to reach top speed. If the dog rings or contact surfaces of this wheel are damaged, you risk an extremely dangerous 5th gear jump or a clean break of the gear set, leading to the immediate immobilization of the vehicle.

The Consequences of a Defective 5th Gear Wheel

Loss of Maximum Speed: Poor engagement due to worn dog rings forces the driver to hold the lever or avoid 5th gear, losing the advantage of the SADEV gear ratio and pure performance.
Multiple Gearbox Damages: A 5th gear wheel that rattles or has play can damage the secondary shaft (on which it is mounted), the bearings, and especially its mating part, the 5th gear pinion, 23 teeth.
Dog Ring Wear and Engagement Difficulties: Rounded dog rings on this wheel no longer allow for clean and fast locking, increasing the gear change time and the fatigue of the entire gear control system.

Maintenance Questions for the ST66 5th Ratio

Should I replace the pinion and wheel set for 5th gear?

Yes, it is essential to replace the pair: 5th gear wheel, 22 teeth (F1903006) and 5th gear pinion, 23 teeth (complementary product available at the bottom of the page). These parts form a synchronized set. Installing a new part with a worn part guarantees the rapid appearance of play and premature wear.

What signs require urgent verification?

Any metallic noise in 5th gear, any difficulty engaging 5th, or a gear jump under heavy acceleration or deceleration are warning signs. A gearbox inspection by a professional is imperative.
