A widely use engine stand can be used.
NOTE:
This example is an engine stand for holding at transaxle
mounting side with flywheel (M/T models) or drive plate (A/T
models) removed.
3. Drain engine oil. Refer to LU-8, "
Changing Engine Oil" .
4. Drain engine coolant by removing water drain plug from inside of
engine.
5. Remove cylinder head. Refer to EM-67, "
CYLINDER HEAD" .
6. Remove knock sensor.
CAUTION:
Carefully handle knock sensor avoiding shocks.
7. Remove crankshaft position sensor (POS).
CAUTION:

Avoid impacts such as a dropping.

Do not disassemble.

Keep it away from metal particles.

Do not place sensor in a location where it is exposed to
magnetism.
8. Remove clutch cover and clutch disc (M/T models). Refer to CL-14, "
CLUTCH DISC, CLUTCH COVER
AND FLYWHEEL" .
9. Remove flywheel (M/T models) or drive plate (A/T models).

Secure crankshaft with a stopper plate, and remove mounting
bolts.

Using the following TORX socket, loosen mounting bolts.
CAUTION:
Be careful not to damage contact surface for clutch disc of
flywheel (M/T models).

a. Apply new engine oil to the threads and seats of connecting rod bolts.
b. Tighten bolts.
c. Then turn all bolts 90 degrees clockwise (Angle tightening).
CAUTION:
Check and confirm the tightening angle by using an angle
wrench (special service tool) or protractor. Avoid judge-
ment by visual inspection without the tool.

After tightening connecting rod bolt, make sure that crankshaft rotates smoothly.

Check the connecting rod side clearance. Refer to EM-99, "CONNECTING ROD SIDE CLEARANCE" .
13. Install flywheel (M/T models) or drive plate (A/T models).

Secure crankshaft with a stopper plate, and tighten mounting bolts crosswise over several times.

Install drive plate, reinforcement plate and pilot converter as
shown in figure (A/T models).

Using a drift of 33 mm (1.30 in) in diameter, press-fit pilot con-
verter into the end of crankshaft until it stops (A/T models).
14. Install knock sensor.

Install knock sensor with connector facing lower left by 45
degrees as shown in the figure.
CAUTION:

Do not tighten mounting bolts while holding the connec-
tor.

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

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

Make sure that knock sensor does not interfere with other
parts.
15. Install crankshaft position sensor (POS).
16. Assemble in the reverse order of disassembly after this step. : 19.6 N·m (2.0 kg-m, 14 ft-lb)
