21008344 S1 Clutch Servo Repair Kit for Volvo FH

What does a clutch servo repair kit do?

This clutch servo repair kit is engineered to renew the sealing elements that undergo frequent wear within the clutch hydraulic circuit. By replacing the seals, O-rings, and dust boots, workshop technicians can restore clutch actuation to its original performance level efficiently. Using high-strength components ensures the kit can withstand the demanding pressures of heavy commercial vehicle operation.

Vehicle and engine compatibility

The kit is specifically compatible with Volvo FH series trucks, including models such as the 400, 420, 440, 460, 480, 500, 520, and 540. This component is designed for use in Volvo FH (FH4/FH5) vehicles featuring the D13K engine. To ensure a proper fit, technicians should verify the cylinder type and bore diameter against the existing unit before installation.

Installation and maintenance guidance

During installation, it is critical to follow precise maintenance steps including correct seal orientation and proper lubrication. For cylinders showing significant scoring on the piston surface or bore damage, a complete unit replacement might be more suitable than a sealing kit. Always ensure the hydraulic system is correctly bled after the repair is completed.

Selection and troubleshooting

Consult your authorized distributor for further information regarding specific fitment and application details.
