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).

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

- When replacing the crankshaft, refer to

EM-304, "Selective-fit Ser-

vice Parts"

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

deposits.

CAUTION:

Never allow gasket fragments to enter oil or engine coolant passages.

• Check flatness of cylinder block upper surface using a straight-

edge (A) and a feeler gauge (B). Measure distortion, at several

points each in six directions.

main bearing housing front side end surface) in two directions, as

shown in the figure. Use the smaller one as the measured value.

• If the result is outside the standard, replace the cylinder block.

NOTE:

Main bearing cap is machined together with cylinder block, so they cannot be replaced separately.

- When replacing the cylinder block, refer to

EM-304, "Selective-fit Service Parts"

Piston-to-cylinder Bore Clearance

Cylinder bore inner diameter

• Use a bore gauge and measure at three points from the top of the

ure) in two directions (“A”, “B”) for measurement at a total of six

points.

NOTE:

The measurement point for bore grade is 60 mm below the cylin-

der head mounting surface (position “D” in the figure). Measure the

dimension in the engine LH/RH directions (“B” in the figure).
