CYLINDER BLOCK

18. Install knock sensor (1).

• Install connectors so that they are positioned towards the rear

of the engine.

CAUTION:

• Never tighten mounting bolt 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.

19. Install crankshaft position sensor (POS) and cover.

• Tighten bolts with it seated completely.

20. For the oil level gauge guide (1), fix the position (B) shown in the

figure to the water inlet clip (A) after inserting to the cylinder
block side.

21. Assemble in the reverse order of disassembly after this step.

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 standard, replace crank-
shaft also.

Measure the inner diameter of piston pin hole with an inside
micrometer.

Piston Pin Outer Diameter 

Measure the outer diameter of piston pin with a micrometer.

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. 

PISTON RING SIDE CLEARANCE

• Measure the side clearance of piston ring and piston ring groove

with a feeler gauge.

• 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

• Make sure that cylinder bore inner diameter is within the specifica-

tion. Check "Cylinder Bore Inner Diameter".

• Lubricate with new engine oil to piston and piston ring, and then

insert piston ring until middle of cylinder with piston, and measure
piston ring end gap with a feeler gauge.

• If the measured value exceeds the limit, replace piston ring.

• Check with a connecting rod aligner.

• If it exceeds the limit, replace connecting rod assembly.

CONNECTING ROD BIG END DIAMETER

• Install connecting rod cap without connecting rod bearing installed, and tightening connecting rod bolts to

the specified torque. Refer to 

EM-101, "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.

CONNECTING ROD SMALL END CLEARANCE

Connecting Rod Small End Inner Diameter

Measure the inner diameter of connecting rod small end with an
inside micrometer.

Connecting Rod Small End Clearance

(Connecting rod small end clearance) = (Connecting rod small end inner diameter) – (Piston pin outer diame-
ter)

• If the measured value is out of the standard, replace connecting rod assembly and/or piston and piston pin

assembly.

• If replacing connecting rod assembly, use "CONNECTING ROD BEARING OIL CLEARANCE" to select con-

necting rod bearing.

CYLINDER BLOCK TOP SURFACE DISTORTION

• Using a 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.

• Measure the distortion on the cylinder block upper face at some

different points in six directions with a straight edge and a feeler
gauge.

• If it exceeds the limit, replace cylinder block.

MAIN BEARING HOUSING INNER DIAMETER

• Install main bearing cap without main bearings installed, and tighten main bearing cap bolts to the specified

torque. Refer to 

EM-101, "Disassembly and Assembly"

.

• Measure the position shown in the figure [5 mm (0.196 in) rear-

ward from main bearing housing front side end surface) in the 2
directions as shown in the figure. The smaller one is the measured
value.

• If out of the standard, replace cylinder block and main bearing

caps as an assembly. 
NOTE:
These components cannot be replaced as a single unit, because they were processed together.
