DISASSEMBLY
1. Remove engine assembly from vehicle, and separate front suspension member and transmission from
engine. Refer to EM-101, "
ENGINE ASSEMBLY" .
2. Remove engine mounting brackets (RH and LH). Refer to EM-101, "
ENGINE ASSEMBLY" .
3. Remove the parts that may restrict installation of engine to widely use engine stand.
NOTE:
The procedure is described assuming that you use a widely use engine stand holding the surface, to
which transmission is installed.
Remove clutch cover and clutch disk (M/T models). Refer to CL-16, "CLUTCH DISC, CLUTCH
COVER" .
Remove flywheel (M/T models) or drive plate (A/T models). Fix crankshaft with a ring gear stopper
[SST: KV10118600 (J-48641)], and remove mounting bolts.
Loosen mounting bolts in diagonal order.
Check for deformation or damage (A).
CAUTION:
Do not disassemble drive plate.
Never 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.
4. Remove pilot bushing (M/T models) or pilot converter (A/T mod-
els) using pilot bushing puller [SST: ST16610001 (J-23907)] (A)
or suitable tool as necessary.
5. Lift the engine with hoist to install it onto the widely use engine stand.
A widely use engine stand can be used.
CAUTION:
Use engine stand that has a load capacity [approximately
220 kg (485 lb) or more] large enough for supporting the
engine weight.
NOTE:
This example is engine stand for holding at transmission
mounting side with flywheel (M/T models) or drive plate (A/T
models) removed.
6. Drain engine oil. Refer to LU-7, "
Changing Engine Oil" .

13. Install connecting rod bearing cap.
Match the stamped cylinder number marks on connecting rod
with those on connecting rod bearing cap to install.
Be sure that front mark (H) on connecting rod bearing cap is
facing front of engine.
14. Inspect the outer diameter of connecting rod bolt. Refer to EM-133, "
LOWER CYLINDER BLOCK BOLT
OUTER DIAMETER" .
15. Tighten connecting rod bolts as follows:
a. Apply engine oil to the threads and seats of connecting rod bolts.
b. Tighten connecting rod bolts.
c. Completely loosen connecting rod bolts.
d. Tighten connecting rod bolts.
e. Then turn connecting rod bolts 90 degrees clockwise (angle
tightening).
CAUTION:
Use angle wrench [SST: KV10112100 (BT8653-A)] (A) to check tightening angle. Do not make judgment
by visual inspection.
After tightening connecting rod bolts, make sure that crankshaft rotates smoothly.
Check the connecting rod side clearance. Refer to EM-125, "CONNECTING ROD SIDE CLEARANCE" .
16. Install baffle plate.
17. Install new rear oil seal. Refer to EM-86, "
OIL SEAL" .
18. Install pilot bushing (M/T models) or pilot converter (A/T mod-
els).
With drift of the following outer diameter, press-fit as far as it
will go.

2. Determine the bore grade by comparing the measurement with
the values under the cylinder bore inner diameter of the “Piston
Selection Table”.
3. Select piston of the same grade.
Piston Selection Table
Unit: mm (in)
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.)
No second grade mark is available on piston.
HOW TO SELECT CONNECTING ROD BEARING
When New Connecting Rod and Crankshaft are Used
1. “Connecting Rod Bearing Selection Table” rows correspond to
connecting rod big end diameter grade (D) stamped on side face
of connecting rod.
2. “Connecting Rod Bearing Selection Table” columns correspond
to pin journal diameter grade (E - J) on front side of crankshafts.
A : Piston grade number
B : Front mark
C : Piston pin grade number

Piston Pin Outer Diameter
Measure the outer diameter of piston pin with micrometer.
Connecting Rod Bushing Oil Clearance
(Connecting rod bushing oil clearance) = (Connecting rod bushing inner diameter) – (Piston pin outer diame-
ter)
If the measured value exceeds the limit, replace connecting rod assembly and/or piston and piston pin
assembly.
If replacing piston and piston pin assembly, refer to EM-119, "HOW TO SELECT PISTON" .
If replacing connecting rod assembly, refer to EM-131, "CONNECTING ROD BEARING OIL CLEAR-
ANCE" to select the connecting rod bearing.
Factory installed parts grading:
Service parts apply only to grade “0”.

CYLINDER BLOCK DISTORTION
Using scraper, remove gasket on the cylinder block surface, and also remove engine oil, scale, carbon, or
other contamination.
CAUTION:
Be careful not to allow gasket flakes to enter engine oil or engine coolant passages.Standard : 21.989 - 22.001 mm (0.8657 - 0.8662 in)
