Concentric Slave Cylinder (CSC) - Causes of Leaks and How to Fix Them
Concentric Slave Cylinder (CSC) - Causes of Leaks
A clutch is a vital part of many vehicles, and a crucial component of that system is the slave cylinder (CSC).concentric slave cylinder Seemingly small mistakes while operating or repairing a vehicle can damage this key component and prevent it from functioning properly. This can lead to a clutch pedal that won't move, making the vehicle undriveable.
Concentric Slave Cylinders (CSC) are used in push type clutch systems to operate the clutch. They are a hydraulically self contained unit that mounts on the gearbox casing and operates the clutch independently from the input shaft of the transmission. They are commonly seen in racing applications and feature a choice of three different fulcrum diameters and a hardwearing low friction coating on all sealing surfaces.
As space constraints have become more important, it is becoming increasingly common for manufacturers to use a fully or semi-hydraulic system. In these systems, there is a master cylinder that is located under the dashboard and connected to a hose and hydraulic connector that runs from the engine to the slave cylinder, which is positioned in the bellhousing.
The slave cylinder is a hydraulically operated piston which is slidably mounted in the bore of the housing. A release bearing is slidably mounted on the piston, and when the piston is pushed in by hydraulic pressure from the master cylinder, it is urged against the annular seal in the housing by the elastomeric annular washer and is restrained from moving from its retracted position by the throw-out bearing. Hydraulic seals are operative between the slave cylinder and housing to prevent hydraulic fluid from leaking past the piston.
