12. Install internal chain guide and timing chain tensioner (primary).
13. Install slack guide.
CAUTION:
Do not overtighten slack guide mounting bolts. It is normal
for a gap to exist under the bolt seats when mounting bolts
are tightened to specification.
14. Install chain tensioner for slack guide.

When installing chain tensioner, push in sleeve and keep it
pressed in with stopper pin.

Remove any dirt and foreign materials completely from the
back and the mounting surfaces of chain tensioner.

After installation, pull out stopper pin by pressing slack guide.
15. Reconfirm that the mating marks on sprockets and timing chain have not slipped out of alignment.

VALVE SEAT CONTACT

After confirming that the dimensions of valve guides and valves
are within specifications, perform this procedure.

Apply prussian blue (or white lead) onto contacting surface of
valve seat to check the condition of the valve contact on the sur-
face.

Check if the contact area band is continuous all around the cir-
cumference.

If not, grind to adjust valve fitting and check again. If the contact-
ing surface still has NG conditions even after the re-check,
replace valve seat.
VALVE SEAT REPLACEMENT
When valve seat is removed, replace with oversized (0.5 mm, 0.020 in) valve seat.
1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.

Be sure to ream in circles concentric to the valve guide center.
This will enable valve to fit correctly.
3. Heat cylinder head to 110 to 130°C (230 to 266°F) by soaking in
heated oil.
4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head.
CAUTION:

Avoid directly touching cold valve seats.

Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.

14. Install connecting rod bearings to connecting rod and connect-
ing rod cap.

When installing connecting rod bearings, apply engine oil to
the bearing surface (inside). Do not apply engine oil to the
back surface, but thoroughly clean it.

When installing, align connecting rod bearing stopper protru-
sion with the cutout of connecting rod to install.

Check the oil hole on connecting rod and that on the corre-
sponding bearing are aligned.
15. Install piston and connecting rod assembly to crankshaft.

Position crankshaft pin corresponding to connecting rod to be
installed onto the bottom dead center.

Apply engine oil sufficiently to cylinder bore, piston and crank-
shaft pin.

Match cylinder position with the cylinder number on connect-
ing rod to install.

Using a piston ring compressor (SST) or suitable tool, install
piston with the front mark on the piston crown facing the front
of engine.
CAUTION:
Be careful not to damage cylinder wall and crankshaft pin, resulting from an interference of con-
necting rod big end.
16. Install connecting rod cap.

Match the stamped cylinder number marks on connecting rod
with those on cap to install.

Be sure that front mark on connecting rod cap is facing front
of engine.
17. Tighten connecting rod bolt as follows.
a. Apply engine oil to the threads and seats of connecting rod
bolts.
b. Tighten bolts.
c. Then tighten all bolts “90” degrees clockwise (Angle tightening).
CAUTION:
Always use an angle wrench [SST: KV10112100 (BT8653-
A)]. Avoid tightening based on visual check alone.

After tightening bolt, make sure that the crankshaft rotates
smoothly.

Check the connecting rod side clearance. Refer to EM-136, "CONNECTING ROD SIDE CLEARANCE"
18. Install baffle plate to main bearing beam.

1. Bore out old seat until it collapses. Boring should not continue beyond the bottom face of the seat recess
in cylinder head. Set the machine depth stop to ensure this.
CAUTION:
Prevent to scratch cylinder head by excessive boring.
2. Ream cylinder head recess diameter for service valve seat.

4. Provide valve seats cooled well with dry ice. Force fit valve seat into cylinder head.
CAUTION:

Avoid directly touching cold valve seats.

Cylinder head contains heat. When working, wear protective equipment to avoid getting burned.
5. Using valve seat cutter set (commercial service tool) or valve
seat grinder, finish seat to the specified dimensions.
CAUTION:
When using valve seat cutter, firmly grip cutter handle with
both hands. Then, press on the contacting surface all
around the circumference to cut in a single drive. Improper
pressure on with cutter or cutting many different times may
result in stage valve seat. Oversize [0.5 mm (0.020 in)]
Intake : 37.500 - 37.516 mm (1.4764 - 1.4770 in)

15. Tighten the connecting rod nuts as follows:
a. Apply engine oil to the threads and seats of connecting rod bolts
and nuts.
b. Tighten nuts.
c. Then tighten all nuts 60 degrees clockwise. (Angle tightening)
CAUTION:
Use angle wrench (SST) to check tightening angle. Do not
make judgment by visual inspection.

After tightening nuts, make sure that the crankshaft rotates
smoothly.

Check the connecting rod side clearance. Refer to EM-256, "CONNECTING ROD SIDE CLEARANCE"
.
16. Install knock sensor.

Install it with its connector facing the rear of engine.

Install the sub-harness with its shorter branch line to the right
bank.
CAUTION:

Do not tighten mounting bolts while holding connector.

If any impact by dropping is applied to knock sensor,
replace it with new one.
NOTE:

Make sure that there is no foreign material on the cylinder
block mating surface and the back surface of the knock sen-
sor.

Make sure that the knock sensor does not interfere with other parts.
17. Install in the reverse order of removal after this step.
18. Remove engine assembly from engine stand.
19. Install drive plate.

Align guide pin of crankshaft rear end with pin holes of each
parts to install.

Install drive plate, reinforcement plate and pilot converter (if
not installed in step 4) as shown in the figure.

Face chamfered or rounded edge side to crankshaft.

Holding ring gear with ring gear stopper [SST: J-45476].

Tighten mounting bolts crosswise over several times.

When install pilot converter, using drift [outer diameter:
approx. 35 mm (1.38 in)]. Press-fit as far as it will go. : 14.7 N·m (1.5 kg-m, 11 ft-lb)

SQUEAK AND RATTLE TROUBLE DIAGNOSES
Revision: 2004 November 2004 FX35/FX45
TRUNK
Trunk noises are often caused by a loose jack or loose items put into the trunk by the owner.
In addition look for:
1. Trunk lid dumpers out of adjustment
2. Trunk lid striker out of adjustment
3. The trunk lid torsion bars knocking together
4. A loose license plate or bracket
Most of these incidents can be repaired by adjusting, securing or insulating the item(s) or component(s) caus-
ing the noise.
SUNROOF/HEADLINING
Noises in the sunroof/headlining area can often be traced to one of the following:
1. Sunroof lid, rail, linkage or seals making a rattle or light knocking noise
2. Sunvisor shaft shaking in the holder
3. Front or rear windshield touching headlining and squeaking
Again, pressing on the components to stop the noise while duplicating the conditions can isolate most of these
incidents. Repairs usually consist of insulating with felt cloth tape.
SEATS
When isolating seat noise it's important to note the position the seat is in and the load placed on the seat when
the noise is present. These conditions should be duplicated when verifying and isolating the cause of the
noise.
Cause of seat noise include:
1. Headrest rods and holder
2. A squeak between the seat pad cushion and frame
3. The rear seatback lock and bracket
These noises can be isolated by moving or pressing on the suspected components while duplicating the con-
ditions under which the noise occurs. Most of these incidents can be repaired by repositioning the component
or applying urethane tape to the contact area.
UNDERHOOD
Some interior noise may be caused by components under the hood or on the engine wall. The noise is then
transmitted into the passenger compartment.
Causes of transmitted underhood noise include:
1. Any component mounted to the engine wall
2. Components that pass through the engine wall
3. Engine wall mounts and connectors
4. Loose radiator mounting pins
5. Hood bumpers out of adjustment
6. Hood striker out of adjustment
These noises can be difficult to isolate since they cannot be reached from the interior of the vehicle. The best
method is to secure, move or insulate one component at a time and test drive the vehicle. Also, engine RPM
or load can be changed to isolate the noise. Repairs can usually be made by moving, adjusting, securing, or
insulating the component causing the noise.
