7485026291 S1 Renault Trucks K Compatible Clutch Servo Kit

What does a clutch servo repair kit do?

A clutch servo repair kit is a service set that brings together the sealing and wear components of the slave cylinder operating in a heavy commercial vehicle's clutch hydraulic circuit. In the system, the master cylinder converts pedal force into hydraulic pressure; the slave cylinder then turns that pressure into mechanical motion, pushing the clutch fork or the release bearing. Over time, the components that actually wear out are not the cylinder body itself but the rubber seals, O-rings, and dust boot inside it.

Compatibility with Renault Trucks K models

This specific kit is compatible with Renault Trucks K models, including the 380T MEDIUM, 430P XTREM, 460P HEAVY, and 520T HEAVY variants. It ensures precise engagement and durability for various configurations like the 430P MEDIUM and 480P XTREM. By addressing internal wear, this kit helps maintain smooth gear shifting in these heavy-duty applications.

Installation and maintenance guidance

When performing maintenance, technicians should inspect the cylinder bore and piston surface to determine if a sealing kit or a complete kit with a piston is required. Proper installation ensures that hydraulic pressure is effectively converted to mechanical motion without leaks. Regular checks of the dust boot and O-rings can prevent premature system failure.

Troubleshooting gear shifting issues

If gear shifting becomes difficult or pedal feel changes, inspecting the clutch servo assembly is recommended. Using high-strength components during the overhaul process helps extend the service life of the clutch hydraulic circuit.
