CYLINDER BLOCK
Install the rear oil seal after installing the oil pan (upper).
17. Install rear oil seal. Refer to
EM-74, "REAR OIL SEAL : Removal and Installation"
18. Install flywheel (M/T models) or drive plate (CVT models).
M/T models
• Secure crankshaft with a stopper plate (A) and tighten bolts
crosswise over several times.
CVT models
• Secure crankshaft with a stopper plate (A) and tighten bolts
crosswise over several times.
CAUTION:
Do not damage or scratch and contact surface for clutch disc of flywheel.
19. Install knock sensor (1).
• Install connectors so that they are positioned toward the rear
of the engine.
CAUTION:
• Do not tighten bolt while holding the 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.
20. Install crankshaft position sensor (POS) (2) and O-ring (1) and
then install the crankshaft position sensor cover (3) on the cylin-
der block (4).
• Tighten bolts with sensor inserted completely.
CAUTION:
• Avoid impacts such as a dropping.
• Do not disassemble.
• Keep sensor away from metal particles.
• Do not place the sensor in a location where it is exposed
to magnetism.
• Do not reuse O-ring.

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaft
arm when crankshaft is moved fully forward or backward using
suitable tool (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 using suitable tool (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 using suitable tool (A).

CYLINDER BLOCK
Measure the outer diameter of piston pin using suitable tool (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
EM-93, "Disassembly and Assembly"
.
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 factory. 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 suitable tool (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 piston (1) and piston ring (2) with new engine oil and
then insert (A) piston ring until middle of cylinder (B) with piston,
and measure piston ring end gap using feeler gauge (C).
• If the measured value exceeds the limit, replace piston ring, and
measure again. If it still exceeds the limit, replace cylinder block.

• Check using 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
.
• Measure the inner diameter (B) of connecting rod big end using
suitable tool.
• If out of the standard, replace connecting rod assembly.
