Hyundai Genesis Coupe Concentric Slave Cylinder (CSC) Removal & Air Bleeding
Service procedure for a concentric slave cylinder (CSC/clutch): removal and install on the transmission case plus air-bleeding steps, tightening torque 8-10 Nm (0.8-1.0 kgf.m, 2.8-7.2 lb-ft).
This service manual page covers the removal, installation, and air bleeding (adjustment) procedure for the C.S.C (Concentric Slave Cylinder) on a manual transmission. Removal requires first removing the transmission assembly (per the MT group manual transmission removal procedure), then unbolting the C.S.C assembly (B) from the transmission case by removing three bolts (A-3ea). Installation is the reverse: bolt the C.S.C assembly to the transmission case with the three bolts. The air bleeding procedure instructs the technician to disconnect the cap from the concentric slave cylinder air bleeder, insert a vinyl hose in the plug, loosen the plug screw, and press and release the clutch pedal about 10 times. A caution note says to hold the air bleeder body with a spanner so it does not rotate when the plug is loosened or tightened. The plug is tightened while the clutch pedal is pressed (tightening torque: 8~10 Nm, 0.8~1.0 kgf.m, 2.8~7.2 lb-ft), then the pedal is raised by hand. After pressing the pedal three more times, the plug is loosened and retightened with the pedal pressed; this step is repeated two or three times until no bubbles appear in the fluid. Two exploded-view illustrations (SBKCH9061D, SBKCH9041D) show the C.S.C on the transmission case and the bleeder location.

Frequently asked questions
- How do you bleed the concentric slave cylinder (C.S.C)?
- Disconnect the cap from the C.S.C air bleeder and insert a vinyl hose in the plug. Loosen the plug screw, press and release the clutch pedal about 10 times, then tighten the plug while the pedal is pressed and raise the pedal by hand. Press the pedal 3 more times, loosen and retighten the plug with the pedal pressed, and repeat this two or three times until there are no bubbles in the fluid.
- What is the tightening torque for the C.S.C bleeder plug?
- 8~10 Nm (0.8~1.0 kgf.m, 2.8~7.2 lb-ft).
- Do you have to remove the transmission to replace the concentric slave cylinder?
- Yes. Step 1 of the removal procedure is to remove the transmission assembly (refer to Manual transmission removal in the MT group), then remove the C.S.C assembly from the transmission case by removing 3 bolts.
- What precaution applies when loosening or tightening the bleeder plug?
- Hold the air bleeder body with a spanner so it does not rotate; this holding is needed whenever the plug is loosened or tightened.
- How many bolts hold the C.S.C assembly to the transmission case?
- Three bolts (A-3ea).
