PRECAUTIONS
Revision: 2006 November2007 350Z
PRECAUTIONSPFP:00001
Precautions for Battery ServiceNCS00001
Before disconnecting the battery, lower both the driver and passenger windows. This will prevent any interfer-
ence between the window edge and the vehicle when the door is opened/closed. During normal operation, the
window slightly raises and lowers automatically to prevent any window to vehicle interference. The automatic
window function will not work with the battery disconnected.
Service Notice or PrecautionsNCS00002

Recommended clutch fluid is brake fluid “DOT 3”. Refer to MA-11, "RECOMMENDED FLUIDS AND
LUBRICANTS" .

Never reuse drained clutch fluid.

Be careful not to splash clutch fluid on painted areas.

When removing clutch tube, use a flare nut wrench.

When installing clutch tube, use a flare nut torque wrench.

Use new clutch fluid to clean or wash all parts of master cylinder.

Never use mineral oils such as gasoline or kerosene. It will ruin
the rubber parts of the hydraulic system.

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

Do not disassemble CSC body.
WARNING:
After cleaning clutch disc, wipe it with a dust collector. Do not use compressed air.SBR686C

CAUTION:

Monitor fluid level in the reservoir tank to make sure it does not empty.

Do not spill clutch fluid onto painted surfaces. If it spills, wipe up immediately and wash the
affected area with water.
NOTE:
Do not use a vacuum assist or any other type of power bleeder on this system. Use of a vacuum assist or
power bleeder will not purge all the air from the system.
1. Fill the master cylinder reservoir tank with new clutch fluid.
2. Connect a transparent vinyl hose to the air bleeder valve.
3. Depress clutch pedal slowly and fully several times at an interval
of 2 to 3 seconds and hold it.
4. With clutch pedal depressed, open air bleeder valve to release
air.
5. Close air bleeder valve.
6. Release clutch pedal and wait for 5 seconds.
7. Repeat steps 3 to 6 until no bubbles can be observed in the
clutch fluid.
8. Tighten air bleeder valve to the specified torque. Refer to CL-11,
"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.

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.

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-

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" .

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

Maximum backlash of spline
: 1.0 mm (0.039 in)
