CSC Contamination

Indicator
Concentric Slave Cylinder (CSC) leaking/no pedal

Cause
1. The CSC has been exposed to fluid contamination with either engine or transmission oil compromising the seal.
2. Incorrect fluid used in the hydraulic system

Effect
The internal rubber seal swells due to the contamination and in some cases splits

Action
1. Identify why the CSC has oil contamination and repair the leak (engine: rear mail seal, rocket cover gaskets – transmission: front shaft seal)
2. Thoroughly clean the back of the engine and transmission bellhousing to remove any oil residue
3. Replace the CSC
4. Flush the clutch hydraulic fluid system using the manufacturers recommended fluid.
