CAUTION:

If transmission assembly is removed from the vehicle, always replace CSC (Concentric Slave Cyl-
inder) body and CSC tube. Return CSC body insert to original position to remove transmission
assembly. Dust on clutch disc sliding parts may damage seal of CSC body and may cause clutch
fluid leakage.

Do not disassemble CSC body.

Keep painted surface on the body or other parts free of clutch fluid. If it spills, wipe up immediately
and wash the affected area with water.

6. Install CSC tube mounting bolt and then tighten mounting bolt to
the specified torque. Refer to CL-11, "
COMPONENTS" .
CAUTION:
Assemble the components checking that the bracket (A) on
the CSC body and the nozzle (B) closely contact each other
before tightening the bolt. When assembled correctly, the
components should not move beyond the allowable loose-
ness of the connector on the CSC body.
7. Install transmission assembly to the vehicle. Refer to MT-20,
"INSTALLATION" .

Removal and InstallationNCS0000D
Carefully observe the following steps during clutch tube removal and installation.

Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the affected area
with water.

When fixing clutch hose to bracket, align clutch hose metal fit-
tings with bracket positioning emboss and lock plate to secure.
At this time, prevent twisting or damage of clutch hose. In addi-
tion, be careful not to damage clutch hose.

Tighten clutch tube flare nut to the specified torque.
CAUTION:
Be careful not to damage flare nut and clutch tube.

After installation, bleed the clutch hydraulic system. Refer to CL-
7, "Bleeding" .

COMPONENTS
CAUTION:

If transmission assembly is removed from the vehicle, always replace CSC (Concentric Slave Cyl-
inder) body and CSC tube. Return CSC body insert to original position to remove transmission
assembly. Dust on clutch disc sliding parts may damage seal of CSC body and may cause clutch
fluid leakage.

Be careful not to bring any grease into contact with the clutch disc facing, pressure plate surface
and flywheel surface.

If flywheel is removed, align dowel pin with the smallest hole of flywheel. Refer to EM-111,
"ASSEMBLY" .

When installing, be careful that grease applied to main drive gear does not adhere to clutch disc.

Do not clean in solvent on clutch disk.
REMOVAL
1. Remove transmission assembly from the vehicle. Refer to MT-18, "Removal and Installation" .
2. Loosen clutch cover mounting bolts with power tool. Remove clutch cover and clutch disc.
CAUTION:
Do not drop clutch disc.

INSPECTION AND ADJUSTMENT AFTER REMOVAL
Clutch Disc

Measure circumference runout relative to the clutch disc center
spline. If it is outside the specification, replace clutch disc and
clutch cover as a set.

Measure backlash for clutch disc spline and main drive shaft
spline at the circumference of the clutch disc. If it is outside the
specified range, replace clutch disc and clutch cover as a set.

Using calipers, measure the depth to the clutch disc facing rivet
heads. If it exceeds the allowable wear limit, replace clutch disc
and clutch cover as a set.
Clutch Cover
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.

Check clutch cover thrust ring for wear or breakage. If wear or
breakage is found, replace clutch disc and clutch cover as a set.
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 disc and clutch cover
as a set.
INSTALLATION
1. Apply recommended grease to clutch disc and main drive gear spline.
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 body, it cause clutch fluid leakage. Wipe off excess grease. Wipe off any grease oozing from
the parts.Runout limit/diameter of the area to be measured
: 1.0 mm (0.039 in)/230 mm (9.06 in) dia.
Maximum backlash of spline

and install clutch aligning bar.
CAUTION:
If either clutch disk or clutch cover is needed to be
replaced, replace them as a set.
3. Tighten clutch cover mounting bolts evenly in two steps in the
order shown in the figure. Refer to CL-16, "
