You’re not alone if you’ve ever wondered what a central slave cylinder is. It is a vital piece of hydraulic equipment that regulates the flow of fluid from the transmission to the engine. Central slave cylinders are classified into two types: push-pull and concentratic. The distinction between them is based on how they operate. 

 The slave cylinder in a push-pull transmission controls the flow of fluid to the engine. Slave cylinders that are concentrated A concentric slave cylinder has a stepped bore with a larger and smaller cross sectional area in the first portion. The piston is mounted on a release bearing and has a correspondingly shaped outer periphery. 

 This cylinder is frequently used in vehicles that require a precise level of hydraulic pressure. It’s also a popular material for car clutches and brakes. The unit has a variety of features depending on the type of concentric slave cylinder used. A spring-loaded return acts on a clutch fork to return the slave cylinder to the transmission front plate in one type. 

 The other type is bolted to the transmission’s front retainer, and both require dimensional distances to keep the clutch finger travel range within the clutch finger travel range. Shims are typically used in concentratic slave cylinders to maintain a tight contact between the bearing face and the diaphragm spring fingers. Slave cylinders with push-pull action A push-pull or central slave cylinder consists of two movable members connected by a shaft. The slave cylinder is a movable member composed of two coaxially disposed and joined tubular members. 

 A bleed port is connected to the slave cylinder’s piston sleeve, and the slave cylinder output member is connected to it via a conventional connector or flexible conduit. The slave cylinder is also linked to a hose that runs from the master cylinder to the top of the block, where there is a bleed valve. The master cyclinder contains an input that is operated by the release pedal on a motor vehicle to operate the central slave cylinder. When hydraulic fluid is supplied through the master cylinder, the input rod is attached to a piston, which displaces. The hydraulic fluid is then transferred via a conduit, which can be either direct or a line. 

 The slave cylinder displaced the piston in the direction of the displaced piston during clutch engagement or disengagement. Replacing a slave cylinder If you have the right tools and know-how, changing a central slave cylinder can be a fairly simple process. The main issue with replacing this cylinder is that it is located beneath the car, making access difficult. 

 This is why most people choose to work from a ladder. Furthermore, the cylinder’s mounting flange is invisible when mounted, so you must remove the dashboard to inspect the cylinder. If your central slave cylinder is not working properly, it is possible that it needs to be replaced. You can substitute two short sections and brass guide sleeves for it. The cylinder can then be slid over the mounting studs.

To ensure that it is securely installed, index it into the clutch return lever indentation. To eliminate squeaks and noises, lubricate the piston rod with grease. We hope that this description can let you clearly know what is the real Central Slave Cylinder.
