CAUTION:

• Never reuse CSC (Concentric Slave Cylinder). Because CSC slides back to the original position

every time when removing transaxle assembly. At this timing, dust on the sliding parts may damage
a seal of CSC and may cause clutch fluid leakage. Refer to

CL-30, "Removal and Installation"

.

• Never bring any grease to the clutch disc facing, pressure plate surface and flywheel surface.
• Never clean clutch disc using solvent.

Apply recommended grease to clutch disc

and input shaft

splines area

. For recommended grease, refer to

CL-32,

"MR20DD : Exploded View"

.

CAUTION:

Be sure to apply grease to the points specified. Otherwise,
noise, poor disengagement, or damage to the clutch may
result. Excessive grease may cause slip or judder. And if it
adheres to seal of CSC, it cause clutch fluid leakage. Wipe
out excess grease. Wipe out any grease oozing from the
parts.

3.

Install clutch disc using clutch aligner (A) (commercial service
tool), and temporarily install clutch cover.

CAUTION:

• Never drop clutch disc and clutch cover.

• Be careful with the orientation of the clutch disc.

4.

Tighten clutch cover mounting bolts to the specified torque
evenly in two steps in the numerical order as shown in the fig-
ure.
• For tightening torque, refer to

CL-32, "MR20DD : Exploded

View"

.

• After installation, perform inspection. Refer to

CL-33,

"MR20DD : Inspection"

CLUTCH DISC AND CLUTCH COVER

• Measure circumferential runout relative to clutch disc center spline.

If it is outside the specification, replace clutch disc.

• Measure backlash to clutch disc spline and input shaft spline at the

circumference of clutch disc. If it is outside the specification,
replace clutch disc.

• Measure the depth (A) to clutch disc facing rivet heads, using a

calipers. If it exceeds the allowable wear limit, replace clutch disc.

Clutch Cover

• Check clutch cover thrust ring for wear or breakage. If wear or breakage is found, replace clutch cover.

NOTE:
• Worn thrust ring will generate a beating noise when tapped at the rivet with a hammer.
• Broken thrust ring will make a clinking sound when cover is shaken up and down.

• If a trace of burn or discoloration is found on the clutch cover pressure plate to clutch disc contact surface,

repair the surface with sandpaper. If surface is damaged or distorted, replace clutch cover.

INSPECTION AFTER INSTALLATION

Check diaphragm spring lever claws for unevenness with the lever
still on the vehicle. If they exceed the tolerance, adjust lever height,
using the diaphragm adjusting wrench (A) (SST: ST20050240).
