A slave cylinder fitting that is concentric is a crucial component of a hydraulic clutch system. If your vehicle’s clutch system is hydraulic, you must attach a hydraulic hose to the cylinder. The rapid attach method is inefficient and necessitates a hydraulic pipe connection. Fortunately, options exist. Here are few.

Difficulties with concentric slave cylinder connections

Ensure the slave cylinder is disconnected from the hydraulic hose prior to disassembling it. Then unscrew it with the shoulder towards the housing of the clutch. Next, ensure that the pushrod is sideways and clear of the release lever. A wooden wedge can also be used to hold the cylinder in place. Then, forcefully push the cylinder out.

The replacement tube should be linked to the hydraulic pipe via the slave cylinder’s fluid port. When removing the new hydraulic tube, be cautious not to damage the body of the slave cylinder. It is essential to route the new hydraulic tube in the same manner as the previous one.

Hydraulic pipe connection size

It is essential to choose the suitable hydraulic pipe connection size for concentric slave cyl fittings. A larger slave cyl will have the same effect as a smaller slave cyl, but it will have greater pedal pressure and release travel at the thrust bearing. A big m/cyl will result in increased pedal pressure, but may also increase mechanical friction in the system.

Ensure you purchase slave cylinders with both male and female fittings. Typically, the female fitting is smaller than the male fitting. The male OD connection is incompatible with the female slave cylinder. In addition, you must ensure that the hose and pipe connections are of the correct size.

In addition to the size of the hydraulic pipe connection, the fittings must be able to support the hose size.

emplacement of the hydraulic pipe connection

To ensure that the hydraulic pipe connection for concentric slave cylinders is centered, check that the cylinder’s bellhousing connection is flush and tight. Do not overtighten the screws, as this could cause the guide sleeve to separate from the bell housing and the seal to separate.Concentric Slave Cylinder Fittings.

Apply extra sealant to the cylinder if necessary.
