e. Then turn all connecting rod cap bolts 60 degrees clockwise (angle tightening).
CAUTION:
Check and confirm the tightening angle by using an angle
wrench [SST: KV10112100 (BT8653-A)] (A) or protractor.
Never judge by visual inspection without the tool.
• After tightening connecting rod cap bolt, check that crankshaft rotates smoothly.
• Check the connecting rod side clearance. Refer to
13. Install oil pan (upper). Refer to
.
NOTE:
Install the rear oil seal after installing the oil pan (upper).
14. Install rear oil seal. Refer to
EM-98, "REAR OIL SEAL : Removal and Installation"
15. Install flywheel (M/T models) or drive plate (CVT models).
Drive plate (CVT models)
• Secure crankshaft with a stopper plate [SST: KV11105210 (J-
44716)], (A) and tighten mounting bolts crosswise over several
times.
• Install pilot converter (1), drive plate (2), and reinforcement
plate (3) as shown in the figure.
• Using a drift of 33 mm (1.30 in) in dia meter, press-fit pilot con-
verter into the end of crankshaft until it stops.
Fly wheel (M/T models)
• Secure crankshaft with a stopper plate [SST: KV11105210 (J-44716)] and tighten mounting bolts cross-
wise over several times.
NOTE:
M/T models have no pilot bushing and reinforcement plate.
16. Install knock sensor.

• Install knock sensor (1) with harness connector facing toward
the rear of engine.
CAUTION:
• Never tighten mounting bolts while holding the harness
connector.
• If any impact by dropping is applied to knock sensor,
replace it with a new one.
NOTE:
• Check that there is no foreign material on the cylinder block mating surface and the back surface of
knock sensor.
• Check that knock sensor does not interfere with other parts.
17. Assemble in the reverse order of disassembly.

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward with a dial
indicator (A).
• If the measured value exceeds the limit, replace thrust bearings,
and measure again. If it still exceeds the limit, replace crankshaft
also.
CONNECTING ROD SIDE CLEARANCE
• Measure the side clearance between connecting rod and crank-
shaft arm with a feeler gauge (A).
• If the measured value exceeds the limit, replace connecting rod,
and measure again. If it still exceeds the limit, replace crankshaft
also.
PISTON TO PISTON PIN OIL CLEARANCE
Piston Pin Hole Diameter
Measure the inner diameter of piston pin hole with an inside
micrometer (A).

CYLINDER BLOCK
Measure the outer diameter of piston pin with a micrometer (A).
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pin hole diameter) – (Piston pin outer diameter)
• If oil clearance is out of the standard, replace piston and piston pin assembly.
• When replacing piston and piston pin assembly. Refer to
.
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
grades can be selected. (Only grade “0” is available.)
PISTON RING SIDE CLEARANCE
• Measure the side clearance of piston ring and piston ring groove
with a feeler gauge (A).
• 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
• Check that cylinder bore inner diameter is within specification. Refer to “PISTON TO CYLINDER BORE
CLEARANCE”.
• Lubricate with new engine oil to piston (1) and piston ring (2), and
then insert (A) piston ring until middle of cylinder (B) with piston,
and measure piston ring end gap with a feeler gauge (C).
• If the measured value exceeds the limit, replace piston ring, and
measure again. If it still exceeds the limit, rebore cylinder and use
oversized piston and piston rings.

• Check with a connecting rod aligner.
• If it exceeds the limit, replace connecting rod assembly.
CONNECTING ROD BIG END DIAMETER
• Install connecting rod cap (1) without connecting rod bearing
installed, and tightening connecting rod cap bolts to the specified
EM-115, "Disassembly and Assembly"
.
• Measure the inner diameter of connecting rod big end with an
inside micrometer.
• If out of the standard, replace connecting rod assembly.
