21008344 S2 Compatible Clutch Servo Repair Kit for Volvo B13R

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. These high-strength components are essential for maintaining the integrity of the hydraulic pressure required for smooth gear transitions and reliable engagement.

Vehicle and engine compatibility

This specific kit is compatible with Volvo B13R trucks featuring D13K engines. It is designed to meet the rigorous demands of heavy commercial vehicle operations, ensuring that the internal seals and O-rings provide a tight, leak-free environment for the cylinder piston.

Installation and maintenance guidance

When performing installation, workshop technicians should verify the cylinder type and ensure correct seal orientation. It is vital to follow proper lubrication and bleeding steps during assembly to prevent air from entering the hydraulic lines, which can lead to spongy pedal feel or inconsistent engagement.

Troubleshooting and selection

If the cylinder bore shows signs of scoring or excessive wear beyond service limits, a complete unit replacement may be more effective than a seal kit. However, for standard maintenance where the piston remains sound, this kit offers an efficient way to extend component life.

OE cross-reference

306.01.0012.02 (Clutch Servo Repair Kit) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 21008344S2.
