306.01.0097.01 Compatible Clutch Servo Repair Kit — Volvo & Renault

What does a clutch servo repair kit do?

A clutch servo repair kit is a service set that provides the essential wear components—such as seals, O-rings, and dust boots—required to renew the clutch slave cylinder within a heavy commercial vehicle's hydraulic circuit. By replacing these high-wear elements, technicians can restore smooth clutch engagement and prevent fluid leaks at a much lower cost than replacing the entire unit.

Compatible vehicles and engines

This specific kit is engineered for heavy-duty applications and is compatible with Volvo FL (D7E) and Volvo FE (D9B) trucks, as well as Renault Trucks Midlum models equipped with DXi5 or DXi7 engines. It also serves various PACCAR vehicles. For optimal performance, ensure the kit type matches the cylinder design, whether it be an external, concentric, or air-assisted configuration.

Installation and maintenance

During installation, workshop technicians should carefully inspect the cylinder bore for scoring and verify that the new seals are correctly oriented. Using the correct hydraulic fluid class is vital to prevent elastomer swelling. If the internal piston surface shows significant wear, a complete unit replacement may be more effective than a seal-only kit.

Selection guidance

Always verify compatibility by checking the cylinder type and connection points against the removed component to ensure precise fitment during service.
