Hi, welcome to

  1. Attach hose to clutch bleed screw and immerse end of hose in container partially filled with clutch fluid.
  2. Open bleed screw, then fill clutch master cylinder reservoir until fluid is free of air bubbles.
  3. Close bleed screw, then check clutch pedal freeplay, if freeplay exceeds 1/2 inch proceed to step 4.
  4. Open bleed screw, then depress clutch pedal to floor.
  5. Tighten bleed screw.
  6. Repeat steps 4 and 5 until fluid entering container is free of air. NOTE: Check and fill reservoir, as needed, to ensure no air is drawn into system during bleeding.

NOTE: This combination concentric (throwout) bearing/slave cylinder is serviced as an assembly only. The bearing is permanently attached to the cylinder piston and the hydraulic lines are permanently attached to the cylinder. If either the cylinder, bearing or lines become damaged, the entire assembly must be replaced.


  1. Shift transmission into first or third gear, then raise and support vehicle.
  2. Support engine with adjustable jack stand, then disconnect necessary exhaust system components.
  3. Disconnect rear transmissoin mount and bracket from transmission, then remove skid plate or rear crossmember.
  4. Disconnect transfer case shift linkage, vehicle speed sensor wires, vent hose and speedometer cable if equipped.
  5. Disconnect clutch hydraulic lines.
  6. Disconnect transmission shift lever as follows:
    1. Lower transmission/transfer case assembly approximately 3 inches for access to shift lever.
    2. On AX-4, AX-5 or AX-15 transmissions remove the 4 retaining bolts around shift tower.
    3. Remove the 3 retaining bolts on BA-5 transmission.
    4. Lift lever and shift tower out of transmission.
    5. It is not necessary to remove shift lever from floorpan boot. Leave lever in position for later installation.
  1. Mark front and rear propeller shafts for installation alignment, then remove shafts.
  2. Remove crankshaft position sensor, if equipped.
  1. Disconnect hydraulic line at quick disconnect fitting. Push round disc inward to unsnap and separate fittings.
  2. Support transmission/tranfer case with suitable jack, then install safety chains.
  3. Remove clutch housing brace rod.
  4. Remove clutch housing to engine bolts, then remove transmission/transfer case assembly, and lower.
  1. Remove bolts attaching slave cylinder fluid line bracket to clutch housing, then remove insulator and bracket.
  2. Remove cylinder and bearing retaining nut from mounting pin on transmission front case.
  3. Slide cylinder and bearing from transmission input shaft. If cylinder and bearing are to be reinstalled, use care not to damage cylinder lines. If cylinder lines are damaged, the cylinder and bearing assembly must be replaced. NOTE: On replacement cylinder and bearing assemblies, nylon retaining straps are used to hold cylinder piston in place. Do not remove these straps, as they are designed to breakaway during piston movement after installation. After completing installation, bleed clutch hydraulic system.
  1. Install clutch housing on transmission. Torque bolts to specifications.
  2. Install concentric bearing. Secure bearing to mounting pin with new retainer clip.
  3. Lightly lubricate pilot bearing and input shaftsplines with high temperature grease.
  4. Align transmission input shaft and clutch disc splines, then install transmission.
  5. Install and torque clutch housing to engine bolt to specifications. Ensure housing is properly seated.
  6. Lower transmission approximately 3 inches. Ensure transmission is in first or third gear.
  7. Reverse above procedure for installation of shift tower.
  8. Connect concentric bearing hydraulic line and engine timing sensor connector.
  9. Remove jack from under transmission and mount transfer case on jack.
  10. Align tranfer case and transmission shafts, then install transfer case. Torque transfer case to transmission nuts/bolts to specifications.
  11. Remove jack stand from under engine and reposition it under transmission, then remove transmission jack.
  12. Connect transfer case shift linkage. Adjust linkage if necessary.
  13. Connect transmission and tranfer case vent hoses, then the backup light switch and vehicle speed sensor connectors.
  14. Install and connect crankshaft position sensor and speedometer cable, if equipped.
  15. Install rear crossmember or skid plate, then the propeller shafts.
  16. Lower vehicle and check fluid level. Bleed clutch system as necessary.

hope this helps.______________

The hose should just push in and stay there, it has a quick disconnect on it.
