7421965253 S1 Clutch Servo Repair Kit for Renault Trucks C

What does a clutch servo repair kit do?

This clutch servo repair kit serves as a critical service set for renewing the wear components within the clutch hydraulic circuit. In heavy commercial vehicle systems, the slave cylinder converts hydraulic pressure into mechanical motion to engage the clutch; this kit provides the necessary seals and components to restore that essential function without requiring a complete cylinder replacement.

Specifically designed for Renault Trucks C series featuring DXi engines, this kit is compatible with various configurations including the 380T, 480PK, 520T, 440T, 520PK, 380P, 460PK, 460P XLOAD, 460TK, 480TK, 380PK, 520TK, 440TK, 280P, 440PK, 250P, 430PK, 430TK, 380P XLOAD, 480T, 280PK, 430P XLOAD, 320PK, 250PK, and 380TK. It ensures precise fitment for these specific heavy-duty applications.

Installation and maintenance guidance

During installation, workshop technicians should verify that the cylinder bore is within service limits and ensure proper lubrication of the new seals. Correct orientation of the O-rings and dust boot is vital to prevent premature leaks and maintain consistent pedal feel. Proper bleeding of the hydraulic system following installation is required to eliminate air pockets and ensure full engagement.

Troubleshooting and selection

Regular inspection of the clutch servo components can prevent sudden loss of actuation. If symptoms like gear shifting difficulty or a spongy pedal occur, this repair kit offers an economical solution to restore system integrity.
