To keep clean the connecting portion and to avoid dam-
age and foreign materials, cover them completely with
plastic bags or something similar.
5. Disconnect fuel damper and fuel hose assembly from fuel tubes (RH and LH).
CAUTION:
While hoses are disconnected, plug them to prevent fuel from draining.
Do not separate fuel damper and fuel hose.
6. Disconnect harness connector from fuel injector.
7. Loosen mounting bolts in reverse order as shown in the figure,
and remove fuel tube and fuel injector assembly.
CAUTION:
Do not tilt it, or remaining fuel in pipes may flow out from
pipes.
8. Remove spacers on intake manifold (lower).
9. Remove fuel injector from fuel tube as follows:
a. Open and remove clip.
b. Remove fuel injector from fuel tube by pulling straight.
CAUTION:
Be careful with remaining fuel that may go out from fuel
tube.
Be careful not to damage injector nozzles during
removal.
Do not bump or drop fuel injector.
Do not disassemble fuel injector.
10. Remove fuel feed damper.
INSTALLATION
1. Install fuel feed damper.
When handling new O-rings, be careful of the following caution.

CAUTION:
Handle O-ring with bare hands. Do not wear gloves.
Lubricate O-ring with new engine oil.
Do not clean O-ring with solvent.
Make sure that O-ring and its mating part are free of foreign material.
When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not
to twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.
Insert new O-ring straight into fuel tube. Do not decenter or twist it.
Insert fuel feed damper straight into fuel tube (RH).
Tighten mounting bolts evenly in turn.
After tightening mounting bolts, make sure that there is no gap between flange and fuel tube (RH).
2. Install new O-rings to fuel injector paying attention to the following caution.
CAUTION:
Upper and lower O-ring are different. Be careful not to confuse them.
Handle O-ring with bare hands. Never wear gloves.
Lubricate O-ring with new engine oil.
Do not clean O-ring with solvent.
Make sure that O-ring and its mating part are free of foreign material.
When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, do not insert it
quickly into fuel tube.
Insert O-ring straight into fuel injector. Do not decenter or twist it.
3. Install fuel injector to fuel tube as follows:
a. Insert clip into clip mounting groove on fuel injector.
Insert clip so that “protrusion A” of fuel injector matches “cut-
out A” of clip.
CAUTION:
Do not reuse clip. Replace it with a new one.
Be careful to keep clip from interfering with O-ring. If
interference occurs, replace O-ring.
b. Insert fuel injector into fuel tube with clip attached.
Insert it while matching it to the axial center.
Insert fuel injector so that “protrusion B” of fuel tube matches
“cutout B” of clip.
Make sure that fuel tube flange is securely fixed in flange fix-
ing groove on clip.
c. Make sure that installation is complete by checking that fuel
injector does not rotate or come off.
Make sure that protrusions of fuel injectors are aligned with
cutouts of clips after installation.
4. Install spacers on intake manifold (lower).
5. Install fuel tube and fuel injector assembly to intake manifold (lower).
CAUTION:
Be careful not to let tip of injector nozzle come in contact with other parts. Fuel tube side : Black
Nozzle side : Green

Disassembly and AssemblyNBS004PN
DISASSEMBLY
NOTE:
Explained here is how to disassemble with engine stand supporting transmission surface. When using differ-
ent type of engine stand, note with difference in steps and etc.
1. Remove engine assembly from vehicle, and separate front suspension member, transmission from
engine. Refer to EM-244, "
ENGINE ASSEMBLY" .
2. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use widely use engine holding the surface, to which trans-
mission is installed.
a. Remove drive plate.
Holding ring gear with ring gear stopper (SST).
Loosen mounting bolts diagonally order.
CAUTION:
Do not disassemble drive plate.
Do not place drive plate with signal plate facing down.
When handling signal plate, take care not to damage or
scratch it.
Handle signal plate in a manner that prevents it from
becoming magnetized.
b. Remove rear plate.
3. Lift engine with hoist to install it onto widely use engine stand.
CAUTION:
Use engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for
supporting the engine weight.
If the load capacity of stand is not adequate, remove the following parts beforehand to reduce the
potential risk of overturning stand.
–Intake manifolds (upper and lower); Refer to EM-179, "INTAKE MANIFOLD" .
–Exhaust manifold and three way catalyst; Refer to EM-183, "EXHAUST MANIFOLD AND THREE WAY
CATALYST" .
