26. Install flywheel (M/T models) or drive plate (1) (A/T or CVT mod-
els).
• Secure crankshaft using Tool (A), and tighten bolts crosswiseover several times.
NOTE:
A/T model shown CVT and M/T similar.
• Install pilot converter (3), drive plate (1) and reinforcement plate (2) as shown (A/T or CVT models).
• Using a suitable tool of 33 mm (1.30 in) in diameter, press-fit pilot converter into the end of crankshaft until it stops (A/T or
CVT models).
NOTE:
M/T models have no pilot converter and reinforcement plate.
27. Install knock sensor (1) with connector facing toward the rear of engine.
CAUTION:
• Never tighten bolts while holding the connector.
• 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.
28. Install crankshaft position sensor (POS) and crankshaft position sensor (POS) cover.
CAUTION:
• Avoid impacts such as a dropping.
• Keep it away from metal particles.
• Never place sensor in a location wher e it is exposed to magnetism.
29. Install oil filter (for intake valve timing control) (1) in the direction shown.
• Make sure that the oil filter does not protrude from the uppersurface of cylinder block (2) after installation.
30. Assembly is in the reverse order of disassembly. Tool number : KV11105210 (J-44716)

How to Select Piston and Bearing
INFOID:0000000005931034
DESCRIPTION
• The identification grade stamped on each part is the grade for the dimension measured in new condition.
This grade cannot apply to reused parts.
• For reused or repaired parts, measure the dimension accurately. Determine the grade by comparing the measurement with the values of each selection table.
• For details of the measurement method of each part, the reuse standar ds and the selection method of the
selective fitting parts, follow the applicable procedures.
HOW TO SELECT PISTON
When New Cylinder Block is Used
• Check the cylinder bore grade on rear left side of cylinder block (L), and select piston of the same grade.
• If there is a correction stamp mark on the cylinder block, use it as a
correct reference.
When Cylinder Block is Reused
1. Measure the cylinder bore inner diameter. Refer to EM-219, "Inspection After Disassembly".
2. Determine the bore grade by comparing the measur ement with the values under the cylinder bore inner
diameter of the “Piston Selection Table”.

Undersize Bearings Usage Guide
• When the specified connecting rod bearing oil clearance is not obtained with standard size connecting rod
bearings, use undersize (US) bearings.
• When using undersize (US) bearing, measure the connecting rod bearing inner diameter with bearing
installed, and grind the crankshaft pin so that the connecting rod bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft pin to use undersize bearings, keep the
fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).

1. “Main Bearing Selection Table” rows correspond to main bearing
housing grade on rear left side of cylinder block (L).
• If there is a correction stamp mark on cylinder block, use it asa correct reference.
2. Apply main journal diameter grade stamped on crankshaft front side to column in the “Main Bearing Selection Table”.
3. Read the symbol at the cross point of selected ro w and column in the “Main Bearing Selection Table”.
CAUTION:
There are two main bearing selection tables. One is for No. 1, 4 and 5 journals and the other is for
No. 2 and 3 journals. Make certain to use the approp riate table. This is due to differences in the
specified clearances.

When Cylinder Block and Crankshaft are Reused
1. Measure the dimensions of the cylinder block ma in bearing housing inner diameter and crankshaft main
journal diameter individually. Refer to EM-219, "
Inspection After Disassembly" and EM-219, "Inspection
After Disassembly".
2. Apply the measured dimension to the “Main Bearing Selection Table”.

Use Undersize Bearing Usage Guide
• When the specified main bearing oil clearance is not
obtained with standard size main bearings, use under-
size (US) bearing.
• When using undersize (US) bearing, measure the main bearing inner diameter with bearing installed, and grind main journal so that the main bearing oil clearance satisfies the standard.
CAUTION:
In grinding crankshaft main jour nal to use undersize bearings,
keep the fillet R [1.5 - 1.7 mm (0.059 - 0.067 in)] (A).

CRANKSHAFT END PLAY
• Measure the clearance between thrust bearings and crankshaftarm 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.

• 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).
Piston Pin Outer Diameter
Measure the outer diameter of piston pin with a micrometer (A).
Piston to Piston Pin Oil Clearance
(Piston to piston pin oil clearance) = (Piston pi n 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, follow the "Piston to Cylinder Bore Clearance" procedure. 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, nogrades can be selected. (Only grade “0” is available.)
