About clutch servo repair kits

Clutch servos use air to assist the driver in disengaging heavy truck clutches, reducing pedal effort.

When to replace

A heavy clutch pedal, air leaking at the servo or fluid on the air side are the typical signs of worn servo seals.

What's in the kit

Clutch servo kits contain piston seals, valve rubbers, O-rings and boots for the servos in the range. All 58 clutch servos lines are manufactured by Pitchline Engineering in an ISO 9001 environment in Pinetown and supplied from our Pinetown branch across South Africa.

Clutch Servos questions

Why has my truck clutch become heavy?

Reduced servo assistance from leaking seals is a frequent cause. Rebuilding the clutch servo restores assistance.

Can a clutch servo leak brake fluid into the air system?

Yes, when the hydraulic seals wear. A repair kit replaces both the hydraulic and air seals.

How do I order clutch servo kits?
