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.

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.

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)]

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)
