Removal and InstallationECS00FT0
CAUTION:

If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylin-
der). Return CSC insert to original position to remove transaxle assembly. Dust on clutch disc
sliding parts may damage CSC seal and may cause clutch fluid leakage.

Keep painted surface of the body and other parts free of clutch fluid. If it spills, wipe up immedi-
ately and wash the affected area with water.
REMOVAL
1. Remove transaxle assembly. Refer to MT-15, "Removal and Installation" .
2. Remove CSC bolts and the CSC from clutch housing.
INSTALLATION
1. Install CSC to clutch housing and then tighten bolts to specification. Refer to MT-17, "Case and Housing
Components" .
CAUTION:

Do not reuse CSC.

Do not insert and operate CSC because piston and stopper of CSC components may fall off.
2. Install transaxle assembly. Refer to MT-15, "
Removal and Installation" .
3. Bleed the air from the clutch hydraulic system. Refer to CL-8, "
Air Bleeding Procedure" .

COMPONENTS
CAUTION:

If transaxle assembly is removed from the vehicle, always replace CSC (Concentric slave cylin-
der). Return CSC insert to original position to remove transaxle assembly. Dust on clutch disc
sliding parts may damage CSC seal and may cause clutch fluid leakage.

Be careful not to apply any grease to the clutch disc facing, pressure plate surface and flywheel
surface.
REMOVAL
1. Remove transaxle assembly from the vehicle. Refer to MT-15, "Removal and Installation" .
2. Loosen clutch cover bolts evenly. Then remove clutch cover and clutch disc.
INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc

Check clutch disc for backlash of spline and runout of facing.

Check clutch disc for burns, discoloration or oil or grease leak-
age. Replace if necessary.

Measure backlash to clutch disc spline and input shaft spline at
the circumference of clutch disc. If outside the specification,
replace clutch disc.
1. Flywheel 2. Clutch disc *1, *2 3. Clutch cover
Apply lithium-based grease including molybdenum disulphide.
*1. Do not clean in solvent. *2. When installing, be careful that grease applied to input shaft does not adhere to
clutch disc.
WCIA0637E
Maximum backlash of spline
(at outer edge of disc): 1.0 mm (0.039 in)
Distance of runout check point
(from hub center): 215 mm (8.46 in)
Maximum allowable spline backlash : 1.0 mm (0.039 in)

CLUTCH DISC, CLUTCH COVER AND FLYWHEEL
Revision: June 20062007 Versa

Use a suitable tool to measure the depth to clutch disc facing
rivet heads. If it exceeds the allowable wear limit, replace clutch
disc.
Clutch Cover
Check clutch cover installed on vehicle for unevenness of diaphragm
spring toe height.

If out of limit, adjust the height using Tool (A).

Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch cover assembly.
NOTE:

Worn thrust ring will generate a beating noise when tapped at
the rivet with a suitable tool.

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 the assembly.
Flywheel Runout

Check contact surface of flywheel for slight burns or discolora-
tion. Repair flywheel with emery paper.

Check the flywheel runout. Refer to EM-103, "FLYWHEEL
DEFLECTION (M/T MODELS)" .
CAUTION:
Measure flywheel outer face (not on knock pin and clutch cover
mounting hole).
INSTALLATION
1. Clean clutch disc and input shaft splines to remove grease and dust caused by abrasion.
2. Apply recommended grease to clutch disc and input shaft splines.
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 shudder. If it adheres to CSC seal, it
will cause clutch fluid leakage. Wipe off excess grease.
3. Install clutch disc using tool.
4. Install clutch cover. Pre-tighten clutch cover bolts.Wear limit of facing
surface to rivet head: 0.3 mm (0.012 in)
