306.01.0012.01 Renault Trucks and Volvo Compatible Clutch Servo Kit

What is a clutch servo repair kit?

A clutch servo repair kit is used to refurbish the clutch actuation system in heavy commercial vehicles. This kit provides an economical solution for restoring hydraulic or air-assisted clutch servos when the cylinder bore remains in good condition.

Vehicle and engine compatibility

This specific kit is designed for a wide range of heavy commercial vehicles, including Renault Trucks models such as the C series, K series, Kerax, Premium, T series, and Magnum. It is also compatible with various Volvo models including FM, FH, FMX, and VNL series. These components are engineered to maintain precise pedal feel and reliable disengagement for fleet operators.

Installation and maintenance guidance

When performing maintenance, technicians should verify if the cylinder bore surface is smooth; if scoring or corrosion is present, a complete replacement is recommended over a seal-only kit. For external-type cylinders, ensure the pushrod length and dust boot fitment are checked against the original unit to ensure correct stroke and free play.

Selection guidance for technicians

Consult your authorized distributor to ensure the specific kit matches the required piston diameter and connection type for your vehicle's engine configuration.
