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

CLUTCH PEDALPFP:46540
On-Vehicle Inspection and AdjustmentNCS00006
1. Check to see if the clevis pin floats freely in the bore of the
clutch pedal. It should not be bound by the clevis or clutch pedal.
a. If the clevis pin is not free, check that the pedal stopper bolt or
ASCD clutch switch is not applying pressure to the clutch pedal
causing the clevis pin to bind. To adjust, loosen lock nut and turn
pedal stopper bolt or ASCD clutch switch.
b. Tighten the lock nut. Refer to CL-6, "
Removal and Installation" .
c. Verify that the clevis pin floats in the bore of the clutch pedal. It
should not be bound by the clutch pedal.
d. If the clevis pin is still not free, remove the clevis pin and check
for deformation or damage. Replace clevis pin if necessary.
Leave pin removed for step 2.
2. Check clutch pedal stroke for free range of movement.
a. With the clevis pin removed, manually move the clutch pedal up and down to determine if it moves freely.
b. If any sticking is noted, replace the related parts (clutch pedal assembly, bushing etc.). Re-assemble the
clutch pedal and re-verify that the clevis pin floats freely in the bore of the clutch pedal.
3. Adjust clearance “C” while depressing clutch pedal fully. (With
clutch interlock switch)
4. Check clutch hydraulic and system components (clutch master
cylinder, CSC, etc.) for sticking or binding.
a. If any sticking or binding noted, repair or replace related parts as
necessary.
b. If hydraulic system repair was necessary, bleed the clutch
hydraulic system. Refer to CL-7, "
Bleeding" .
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.Clearance C : 0.1 - 1.0 mm (0.004 - 0.039 in)

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
