21008344 S2 Compatible 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 wear out most often in the clutch hydraulic circuit, restoring clutch actuation to its original performance at a cost-effective level. It is designed to ensure the longevity of the hydraulic system under heavy-duty service conditions.

Compatible Volvo FH models and engines

This kit is specifically compatible with Volvo FH (FH4/FH5) trucks featuring D13K engines. It also fits various Volvo FH models including 400, 420, 440, 460, 480, 500, 520, and 540 variants. Ensure the cylinder type and seal orientation match the removed component before installation.

Installation and maintenance guidance

When performing maintenance, technicians should verify the bore and piston condition. If the piston surface shows significant scoring or the bore is beyond service limits, a complete unit replacement may be required. Proper lubrication and bleeding of the hydraulic circuit are essential steps during the assembly process.

Troubleshooting and selection

Maintaining the clutch servo ensures consistent pedal feel and smooth gear transitions in heavy commercial vehicles. Consult your authorized distributor for further technical guidance.
