CYLINDER KIA CARNIVAL 2007 Owners Manual

2007 > 2.7L V6 GASOLINE >
DESCRIPTION
SELF ADJUSTING CLUTCH(S.A.C.) COVER
a. As a clutch disc facing is worn away according to its durability, a cover weight is increasing and a clutch pedal
pressure can be more needed.
b. To make up for this defect, the self adjusting clutch system makes the requsted pedal pressure minimized so that
makes the maintenance cycle longer.
CONCENTRIC SLAVE CYLINDER-C.S.C.
It improves working efficiency and lowers the number and the weight of part by unifing clutch release control
parts(clutch release bearing ~ clutch release cylinder) in a manual transaxle.
OPERATION
CONCENTRIC SLAVE CYLINDER-C.S.C
When the clutch pedal is pressed, oil pressure is transmitted along the arrow directions shown below and that moves
the clutch slave cylinder and the diaphragm spring of the clutch cover.

5.Tighten the clutch cover.
TORQUE:
24.5~35.3Nm (250~360kgf.cm, 18.1~26.0lb - ft) (6EA)
When installing the clutch cover, tighten the bolts in diagonal directions not to be bent or twisted.
* Possible problems when not following
a. When tightening the bolt completely at a time: the clutch cover can be twisted and vibration can occur.
b. On vehicles with self adjusting clutches, it is necessary to follow this caution.
c. Not following tightening torque: There can be bad torque transmission in clutch and relaxation possibility of
bolts.
INSPECTION
1.Inspect diaphragm spring wear which is in contact with a concentric slave cylinder bearing.

REMOVAL
Do not spill brake fluid on the vehicle; it may damage the paint if brake fluid does contact the paint, wash it off
immediately with water.
1. Remove the brake fluid fron the clutch master cylinder reservoir with a syringe.
2. Clamp the clutch master cylinder hose(A). If there is no enough room for clamping, you can also clamp the hose
from the brake master cylinder side.
3.Disconnect the hose(A) from the cylinder by releasing the clutch master cylinder clamp.
4.Remove the clutch master cylinder mounting bolts(A,B).
One is the engine room, the other near the clutch pedal assembly.

5.Remove the pin and washer which connect the clutch pedal with the clutch master cylinder.
6. Remove the clutch master cylinder. It can be helpful to do this step after removing the clutch pedal mounting
bracket.
INSTALLATION
Installation is in the reverse order of removal.
After installation, bleed the clutch hydaulic system.
CONCENTRIC SLAVE CYLINDER AIR BLEEDING PROCEDURE
1.After disconnecting a cap from the concentric slave cylinder air bleeder, insert a vinyl hose in the plug.
2. Loosening the plug screw, press and release the clutch pedal about 10 times.
Hold the air bleeder body not to rotate with a spanner(A). The holding is needed when the plug loosened or
tightened.
3. Tighten the plug during the clutch pedal pressed. Afterwards, raise the pedal with a hand.
TORQUE :
25~29Nm (250~290Kgf.cm, 18.2~21.1lb - ft)
4. After pressing the clutch pedal 3 times more, loosen the plug and retighten it with the pedal pressed. Raise it
again, then.
5. Repeat the step 4 two or three times. (until there is no bubble in the fluid)
a.Do not clamp the pipe of a concentric slave cylinder.
b. Be careful not to damage O - rings.

ADJUSTMENT PROCEDURE
IGNITION LOCK SWITCH
1. Disconnect 2P- connector from a ignition lock switch.
2. Disconnect the ignition lock switch. (if you can install a tester with the switch fixed, this step can be omissible)
3. Check for continuity between terminals. (refer to the table below)
Clutch pedal position Ignition lock switch Continuity
Released ReleasedNO
Pressed PressedYES
If there is difference between what tested and the table above, replace the ignition lock switch with a new one.
If not, install the ignition lock switch and adjust the clutch pedal.
TORQUE :
8~10Nm (80~100kgf.cm, 5.8~7.2lb- ft)
Clutch pedal and Ignition lock switch
a. Inspect a ignition lock switch.
b. Remove the driver's seat mat to adjust a clutch pedal.
c. No gap between a clutch master cylinder pistion and push rod can cause clutch slip.
1. Loosen and draw out the bolt until it is off the pedal surface.
2. Push and pull a clutch master cylinder push rod to satisfy the specification below.
Specification:
Clutch pedal stroke(A) - 150mm(5.91in)
Clutch pedal free play(B) - 6~13mm(0.24~0.51in)
Clutch pedal distance - 234.7mm(9.24in)
3.With no pressure on a clutch pedal, tighten the bolt until it contacts on the pedal.
4. Fix the bolt with a nut.
TORQUE :
14~20Nm (140~200kgf.cm, 10.2~14.5lb - ft)

5.Press the clutch pedal to the seat ground.
6. Adjust the ignition lock switch position with the pedal a little(23~26mm) raised.
7. Install the ignition lock switch firmly.
TORQUE:
8~10Nm (80~100kgf.cm, 5.8~7.2lb- ft)
REPLACEMENT
a.Inspect the continuity of the ignition lock switch.
b. Remove the floor mat before adjusting the clutch pedal.

2. Remove the snap pin and the clevis pin(A) connecting the clutch master cylinder push rod and the clutch pedal.
3.Remove the clutch master cylinder mounting nut(A,B) and the clutch pedal mounting nut(C).

4.Remove the clutch pedal.
5. Install a new one by tightening the bolts of the clutch pedal bracket and master cylinder .
TORQUE :
19~26 Nm(19~260 kgf.cm, 13.8~18.9 Ib- ft)(Clutch pedal bracket)
12~16 Nm(120~160 kgf.cm, 8.7~11.6 Ib- ft)(Clutch master cylinder)
