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)

When replacing piston and piston pin assembly, refer to EM-260, "PISTON TO CYLINDER BORE
CLEARANCE" .
NOTE:

Piston is available together with piston pin as assembly.

Piston pin (piston pin hole) grade is provided only for the parts installed at the plant. For service parts,
no piston pin grades can be selected. (Only “0” grade is available.)
PISTON RING SIDE CLEARANCE

Measure side clearance of piston ring and piston ring groove
with feeler gauge.

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
replace piston also.
PISTON RING END GAP

Make sure that cylinder bore inner diameter is within specifica-
tion. Refer to EM-260, "
Cylinder Bore Inner Diameter" .

Lubricate with new engine oil to piston and piston ring, and then
insert piston ring until middle of cylinder with piston, and mea-
sure piston ring end gap with feeler gauge.

If the measured value exceeds the limit, replace piston ring, and measure again. If it still exceeds the limit,
re-bore cylinder and use oversize piston and piston rings.Standard:
Top ring : 0.045 - 0.080 mm (0.0018 - 0.0031 in)
2nd ring : 0.030 - 0.070 mm (0.0012 - 0.0028 in)
Oil ring : 0.065 - 0.135 mm (0.0026 - 0.0053 in)
Limit:

Top ring : 0.11 mm (0.0043 in)

2nd ring : 0.1 mm (0.004 in)
SEM024AA
Standard:
Top ring : 0.22 - 0.32 mm (0.0087 - 0.0126 in)
2nd ring : 0.22 - 0.32 mm (0.0087 - 0.0126 in)
Oil ring : 0.20 - 0.60 mm (0.0079 - 0.0236 in)
Limit:


Top ring : 0.56 mm (0.0220 in)


2nd ring : 0.56 mm (0.0220 in)
Oil ring : 0.96 mm (0.0378 in)

Measure the distortion on the cylinder block upper face at some
different points in six directions with straightedge and feeler
gauge.

If it exceeds the limit, replace cylinder block.
MAIN BEARING HOUSING INNER DIAMETER

Install main bearing caps and main bearing beam without install-
ing main bearings, and tighten main bearing cap bolts to the
specified torque. Refer to EM-244, "
ASSEMBLY" for the tight-
ening procedure.

Measure the inner diameter of main bearing housing with bore
gauge.

If out of the standard, replace cylinder block and main bearing
caps as assembly.
NOTE:
Cylinder block cannot be replaced as single part, because it is
machined together with main bearing caps.
PISTON TO CYLINDER BORE CLEARANCE
Cylinder Bore Inner Diameter

Using bore gauge, measure cylinder bore for wear, out-of-round
and taper at six different points on each cylinder. (“X” and “Y”
directions at “A”, “B” and “C”) (“Y” is in longitudinal direction of
engine)

If the measured value exceeds the limit, or if there are scratches
and/or seizure on the cylinder inner wall, hone or re-bore the
inner wall.

Oversize piston is provided. When using oversize piston, re-
bore cylinder so that the clearance of the piston-to-cylinder bore
satisfies the standard.
CAUTION:
When using oversize piston, use it for all cylinders with
oversize piston rings.Limit : 0.1 mm (0.004 in)

Standard : 68.944 - 68.968 mm (2.7143 - 2.7153 in)

Wear limit:
0.2 mm (0.008 in)
Out-of-round (Difference between “X” and “Y”):
0.015 mm (0.0006 in)
Taper limit (Difference between “A” and “C”):
0.01 mm (0.0004 in)
Oversize (OS) : 0.2 mm (0.008 in)

Checking Exhaust SystemABS005Z5
Check exhaust pipes, muffler and mounting for improper attachment,
leaks, cracks, damage or deterioration.

If anything is found, repair or replace damaged parts.
Removal and InstallationABS005Z6
CAUTION:

Be sure to use genuine exhaust system parts or equivalents which are specially designed for heat
resistance, corrosion resistance, and shape.

Perform the operation with the exhaust system fully cooled down because the system will be hot
just after engine stops.

Be careful not to cut your hand on the heat insulator edge.

Tighten main muffler mounting bracket bolts in numerical order
as shown in the figure.
CAUTION:

Always replace exhaust tube gaskets with new ones when reassembling.

If heat insulator is badly deformed, repair or replace it. If deposits such as mud pile up on the heat
insulator, remove them.

When installing heat insulator avoid large gaps or interference between heat insulator and each
exhaust pipe.

Remove deposits from the sealing surface of each connection. Connect them securely to avoid
gas leakage.

Temporarily tighten mounting nuts on the exhaust manifold side and mounting bolts on the vehi-
cle side. Check each part for unusual interference, and then tighten them to the specified torque.

When installing each mounting rubber, avoid twisting or unusual extension in up/down and right/
left directions.
INSPECTION AFTER INSTALLATION

Make sure clearance between tail tube and bumper is even.

With engine running, check exhaust tube joints for gas leakage and unusual noises.

Check to ensure that mounting brackets and mounting rubbers are installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.

with new ones.
4. Apply grease to the new extension tube O-rings.
5. Install the extension tube into the engine oil sump.
PRE-DISASSEMBLY INSPECTION
Before disassembling the front final drive, perform the following inspection.
To ta l P r e l o a d
1. Place the front final drive onto the attachment and secure it.
