Needle socket HK4012 SADEV / Renault Clio 3 CUP / Renault Clio 2 CUP / ST75-14

HK4012 SADEV needle bushing for ST75-14 sequential gearbox

This HK4012 SADEV needle socket is a new part intended for SADEV ST75-14 sequential gearboxes fitted to Renault Clio 3 CUP and Renault Clio 2 CUP. Designed to meet the requirements of motorsport, it ensures precise and reliable guidance of the internal mechanical elements of the transmission.

Purpose of the part

The function of the needle bush is to reduce friction between rotating or moving parts in the gearbox. It allows compact, resistant and precise guidance, while supporting the high stresses generated by circuit or competition use. In a SADEV sequential gearbox, this type of component directly contributes to the quality of operation, the precision of gear changes and the longevity of the mechanical assembly.

Symptoms or consequences of a worn or defective part

A worn, marked or seized needle bushing can lead to increased mechanical clearances, abnormal friction or progressive deterioration of associated parts. In intensive use, this can result in less smooth operation of the gearbox, internal noises, premature wear of the shafts or gears concerned, or even transmission failure if the part is not replaced in time.

Benefits of replacement

• Restores precise mechanical guidance in the sequential box
• Reduces internal friction and the risk of premature wear
• Contributes to the reliability of the transmission in competition use
• Preserves the performance of the SADEV ST75-14 gearbox
• Allows preventive or corrective maintenance in accordance with motorsport requirements
