    Clutch Slave Cylinder

    Print

    REMOVAL & INSTALLATION



    See Figure 1


    WARNING
    The hydraulic clutch system utilizes DOT 3 brake fluid, which will eat through the vehicle's paint. Clean up any spills immediately.

    1. Disconnect the negative (-) battery cable.
    2.  


    WARNING
    After disconnecting the fluid lines from the clutch component, immediately plug the line. The brake fluid in the system will absorb moisture, which will decrease the system's effectiveness.

    1. Using a flare nut wrench (for systems equipped with flare fittings) or a socket and ratchet wrench (for systems equipped with pinch bolt fittings), remove the fluid line from the slave cylinder. Immediately plug the clutch hydraulic fluid line to prevent excessive clutch fluid leakage or system contamination.
    2.  
    3. Remove the cylinder retaining bolts from the clutch housing and carefully pull the slave cylinder from the transmission housing. Make certain that the slave cylinder separates from the shift fork.
    4.

    Fig. Fig. 1: The slave cylinder fluid line fittings will be either of the flare nut fitting type (left) or the pinch bolt type (right)

    To install:
    1. Install the cylinder, making sure the slave cylinder pushrod is correctly seated against the shift fork, and retaining bolts to the transmission housing. Tighten the slave cylinder bolts until secure.
    2.  
    3. Using a flare nut wrench, install the fluid line to the slave cylinder. Some fluid lines utilize a pinch bolt instead of a conventional brake line fitting. Tighten the fitting/pinch bolt until secure.
    4.  
    5. Connect the cylinder pushrod to the clutch release fork.
    6.  
    7. Bleed the clutch hydraulic system.
    8.  

    HYDRAULIC SYSTEM BLEEDING



    Models Without a Damper Cylinder

    See Figures 2 and 3

    1. Remove the clutch master cylinder reservoir cap.
    2.  
    3. Fill the reservoir with fresh, clean DOT 3 brake fluid to the top, then reinstall the cap.
    4.  
    5. Apply the parking brake and block the rear wheels. Raise and safely support the front of the vehicle with jackstands.
    6.  
    7. Install a vinyl tube to the bleeder screw and insert the other end of the tube into a transparent container.
    8.  
    9. Have an assistant pump the clutch pedal repeatedly, then hold it depressed.
    10.

    Fig. Fig. 3: The bleeder valve location on a common slave cylinder-the exact location may vary slightly from model to model

    1. From under the vehicle, remove the rubber cap from the bleeder valve, open the slave cylinder bleeder screw to release the clutch fluid with bubbles into the container, then tighten the bleeder screw immediately.
    2.  
    3. Have the assistant release the clutch pedal slowly. If the clutch pedal is released while the bleeder screw is open, air will be sucked into the clutch system, necessitating even more bleeding.
    4.  
    5. Inspect the clutch master cylinder level; pour more brake fluid into the reservoir if the level falls below the full mark.
    6.  

    Never allow the clutch master cylinder to run dry.

    1. Repeat Steps 5 through 8 until the fluid released out through the bleeder screw is free of bubbles. This may take several times of releasing the clutch fluid, especially if a large quantity of fluid leaked out of the fluid lines during servicing.
    2.  
    3. Lower the vehicle and remove the rear wheel blocks.
    4.  

    Models With a Damper Cylinder

    See Figures 2, 3 and 4

    A damper cylinder is used on some of the newer vehicles equipped with V6 engines. It is bled in the same manner as the slave cylinder. The damper cylinder keeps the clutch shift fork from snapping back into place too quick when the clutch pedal is released rapidly.

    1. Open the hood.
    2.  
    3. Remove the clutch master cylinder reservoir cap.
    4.  
    5. Fill the reservoir with fresh, clean DOT 3 brake fluid to the top, then reinstall the cap.
    6.  
    7. Remove the rubber cap from the damper cylinder bleeder valve. Install a vinyl tube to the bleeder screw on the damper cylinder and insert the other end of the tube into a transparent container.
    8.

    Fig. Fig. 4: This particular damper cylinder is equipped with a remote bleeder valve (3 fluid lines)

    1. Have an assistant pump the clutch pedal repeatedly, then hold it depressed.
    2.  
    3. Open the damper cylinder bleeder screw to release the clutch fluid with bubbles into the container, then tighten the bleeder screw immediately.
    4.  
    5. Have the assistant release the clutch pedal slowly. If the clutch pedal is released while the bleeder screw is open, air will be sucked into the clutch system, necessitating even more bleeding.
    6.  
    7. Inspect the clutch master cylinder level; pour more brake fluid into the reservoir if the level falls below the full mark.
    8.  

    Never allow the clutch master cylinder to run dry.

    1. Repeat Steps 5 through 8 until the fluid released out through the bleeder screw is free of bubbles. This may take several times of releasing the clutch fluid, especially if a large quantity of fluid leaked out of the fluid lines during servicing.
    2.  
    3. Install the rubber cap onto the damper cylinder bleeder valve.
    4.  
    5. Apply the parking brake and block the rear wheels. Raise and safely support the front of the vehicle with jackstands.
    6.  
    7. Install the vinyl tube onto the slave cylinder bleeder screw and insert the other end of the tube into a transparent container.
    8.  
    9. Repeat Steps 5 through 9 for the slave cylinder.
    10.  
    11. Install the rubber cap on the slave cylinder bleeder valve.
    12.  
    13. Lower the vehicle, remove the rear wheel blocks and close the hood.
    14.  
    15. Test drive the vehicle to ensure that the clutch system is working properly.
    16.
