MOVEMENT AMOUNT OF FLYWHEEL (M/T MODELS)
NOTE:
●Inspection for double mass flywheel only.
●Do not disassembly double mass flywheel.
Flywheel Deflection
●Measure deflection of flywheel contact surface to the clutch with a dial gauge.
●Measure deflection at 210 mm (8.27 in) dia.
●When measured value exceeds the limit, replace it with a new
one.
Movement Amount in Radial (rotation) Direction
Check the movement amount in the following procedure.
1. Install a bolt to clutch cover mounting hole, and place a torque wrench on the extended line of the flywheel
center line.
●Tighten bolt at a force of 9.8 N·m (1.0 kg-m, 87 in-lb) to keep it from loosening.
2. Put a mating mark on circumferences of the two flywheel
masses without applying any load (Measurement standard
points).
3. Apply a force of 9.8 N·m (1.0 kg-m, 87 in-lb) in each direction,
and mark the movement amount on the mass on the transaxle
side.
4. Measure dimensions of movement amounts A and B on circum-
ference of the flywheel on the transaxle side.
●When measured value is outside the standard, replace fly-
wheel.Standard : 0.45 mm (0.0177 in) or less.
Limit : 1.3 mm (0.051 in) or less.

OIL JET
●Check nozzle for deformation and damage.
●Blow compressed air from nozzle, and check for clogs.
●If it out of the standard, replace oil jet.
OIL JET RELIEF VALVE
●Using a clean plastic stick, press check valve in oil jet relief
valve. Make sure that valve moves smoothly with proper reac-
tion force.
●If it is out of the standard, replace oil jet relief valve.
MOVEMENT AMOUNT OF FLYWHEEL
NOTE:
●Inspection for double mass flywheel only.
●Do not disassembly double mass flywheel.

PRECAUTIONS
PRECAUTIONS
PFP:00001
CautionEDS00101
●Before starting diagnosis of the vehicle, understand symptoms well. Perform correct and systematic oper-
ations.
●Check for the correct installation status prior to removal or disassembly. When mating marks are required,
be sure they do not interfere with the function of the parts they are applied to.
●Carry out an overhaul in a clean work place. Using a dust proof room is recommended.
●Before disassembly, using steam or white gasoline, completely remove sand and mud from the exterior of
the unit, preventing them from entering into the unit during disassembly or assembly.
●Check appearance of the disassembled parts for damage, deformation, and abnormal wear. If a malfunc-
tion is detected, replace it with a new one.
●Normally replace lock pins, oil seals, and bearings with new ones every time they are removed.
●In principle, tighten bolts or nuts gradually in several steps working diagonally from inside to outside. If
tightening sequence is specified, observe it.
●Clean and flush the parts sufficiently and blow them dry.
●Be careful not to damage the sliding surfaces and mating surfaces.
●When applying sealant, remove the old sealant from the mounting surface; then remove any moisture, oil,
and foreign materials from the application and mounting surfaces.
●Always use shop paper for cleaning the inside of components.
●Avoid using cotton gloves or a shop cloth to prevent entering of lint.
●During assembly, observe the specified tightening torque, and apply new differential oil, Vaseline, or Nis-
san MP Special Grease No. 2, as specified for each vehicle, when necessary.
●Do not reuse drained oil. Discard waste oil after oil changes or part treatment in accordance with local
laws and regulations.
Precautions for Brake SystemEDS00102
●When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
●After installing removed suspension parts, check wheel alignment and adjust if necessary.
●Use flare nut wrench when removing or installing brake tubes.
●Always torque brake lines when installing.

Removal and InstallationEES00074
REMOVAL
1. Remove tires. Remove brake caliper and hung it aside.
CAUTION:
Avoid depressing brake pedal with brake caliper removed.
2. Remove electrical wires of ABS wheel speed sensor from strut.
3. Remove brake hose lock plate.
4. Remove mounting bolts and nuts securing steering knuckle to strut.
5. Remove mounting nuts on upper mounting plate and remove upper mounting plate and strut from vehicle.
INSTALLATION
●Refer to FSU-5, "Components" in “Front Suspension Assembly” for tightening torque. Tighten in the
reverse order of removal.
●Be sure arrows on strut mount insulator and spring upper seat
are positioned as shown. Also be sure notch in strut spacer is
positioned as shown. Then install strut.
●Assemble upper mounting plate with its notch facing toward the
outside.
Disassembly and AssemblyEES00075
DISASSEMBLY
1. Install strut attachment to strut and fix it in a vise.
CAUTION:
When installing strut attachment, wrap a shop cloth around
strut to protect it from damage.
2. Slightly loosen piston rod lock nut.
WARNING:
Do not remove piston rod lock nut completely. If it is
removed completely, coil spring jumps out and may cause
serious damage or injury.
3. Compress coil spring using a spring compressor.
WARNING:
Make sure that the pawls of the two spring compressors are firmly hooked on the spring. The
spring compressors must be tightened alternately so as not to tilt the spring.
4. After making sure coil spring is free between upper and lower seats after Step 3. Remove piston rod lock
nut.
5. Remove small parts on strut.
●Remove strut spacer, strut mount insulator, thrust bearing, spring upper seats, and upper rubber seats.
Then remove coil spring.
6. Remove bound bumper from spring upper seat.
7. Gradually release spring compressor, and remove coil spring.
INSPECTION AFTER DISASSEMBLY
Strut
●Check strut for deformation, cracks, and damage, and replace if necessary.
●Check piston rod for damage, uneven wear, and distortion, and replace if necessary.
●Check welded and sealed areas for oil leakage, and replace if necessary.
