CYLINDER BLOCK

Check tightening angle with an angle wrench [SST:

KV10112100 (BT8653-A)] A or a protractor. Never estimate

tightening angle visually.

• Check that the crankshaft rotates smoothly by hand after tight-

ening the main bearing cap bolt.

• Check the connecting rod side clearance. Refer to 

EM-294,

"Inspection"

.

14. Install the oil pan (upper). Refer to 

EM-282, "Exploded View"

.

NOTE:

Install the rear oil seal after installing the oil pan (upper).

15. Install rear oil seal. Refer to 

EM-271, "REAR OIL SEAL : Removal and Installation"

.

16. Install knock sensor (1) in the direction shown in the figure.

CAUTION:

• Never subject parts to impact. If any impact is applied,

replace it.

• Check that no foreign material adheres to cylinder block

and knock sensor mounting surfaces.

• Install connectors so that they are positioned toward

engine rear.

• Be sure to use specified bolts.

• Never hold connector while tightening bolts.

• Never allow installed sensor connector to interfere with other parts.

17. Assemble in the reverse order of disassembly.

INSPECTION AFTER DISASSEMBLY

Crankshaft Side Clearance

• Move crankshaft to front or rear, and measure thrust bearing-to-

crank arm clearance using a dial indicator (A).

• If the limit is exceeded, replace the thrust bearing and then mea-

sure again. Replace the crankshaft if it still exceeds the limit.

- When replacing the crankshaft, refer to 

EM-304, "Selective-fit Ser-

vice Parts"

 and select the main bearing and connecting rod bear-

ing.

• Measure connecting rod-to-crank arm side clearance using a

feeler gauge (A).

• If the limit is exceeded, replace the connecting rod, and then mea-

sure again. Replace the crankshaft if it still exceeds the limit.

- When replacing the crankshaft, refer to 

EM-304, "Selective-fit Ser-

vice Parts"

 and select the main bearing and connecting rod bear-

ing.

Piston-to-piston Pin Clearance

Piston pin hole inner diameter

• Measure inner diameter of piston pin hole using an inside

micrometer (A).

Piston pin outer diameter

• Measure piston pin outer diameter using a micrometer (A).

How to calculate piston-to-piston pin clearance

• Calculate the piston pin clearance using the following formula.

(Piston pin clearance) = (Piston pin hole inner diameter) - (Piston pin outer diameter)

• If clearance exceeds the standard, replace piston and piston pin assembly.

- When replacing piston and piston assembly, refer to 

EM-304, "Selective-fit Service Parts"

 and select the cor-

rect parts.

NOTE:

Piston and piston pin are service parts for assembly.

• Measure piston ring-to-piston ring groove clearance using a feeler

gauge (A).

• Replace piston ring if the limit is exceeded (the standard for oil

ring).

• Measure the clearance again. If it still exceeds the limit (the stan-

dard for oil ring), replace piston.

- When replacing the piston, refer to 

EM-304, "Selective-fit Service

Parts"

 and select the correct part.

Piston Ring End Gap

• Check that the cylinder bore inner diameter is within the standard. Refer to 

EM-317, "Cylinder Block"

.

• Apply oil to the piston (1) and the piston ring (2). Using the piston,

press the piston ring into the cylinder center position (B), and then

measure the end gap.

• If the limit is exceeded, replace piston rings.

Connecting Rod Bend and Torsion

• Check connecting rod bend and torsion with a connecting rod

alignment tool.

• Replace the connecting rod assembly if it exceeds the limit.

• Without installing connecting rod bearing, install connecting rod

cap (1) and tighten connecting rod bolt to the specified torque.

Measure connecting rod large end diameter with an inside

micrometer.

- For the connecting rod bolt tightening procedure, refer to 

EM-287,

"Disassembly and Assembly"

.

• Replace the connecting rod assembly if it is outside the standard.

- When replacing the connecting rod, refer to 

EM-304, "Selective-fit Service Parts"

, and select the connecting

rod bearing.

Connecting Rod Small End Clearance

Connecting rod small end inner diameter

• Measure inner diameter of connecting rod small end using an

inside micrometer (A).

Piston pin outer diameter

• Measure piston pin outer diameter using a micrometer (A).

Calculating connecting rod small end clearance

• Calculate the connecting rod small end clearance using the following formula.

(Connecting rod small end clearance) = (connecting rod small end inner diameter) - (piston pin outer diame-

ter)

• Refer to each part standard and replace connecting rod and/or piston and piston pin assembly if the limit is

exceeded.

- When replacing piston and piston assembly, refer to 

EM-304, "Selective-fit Service Parts"

 and select the cor-

rect parts.
