16. INSPECT PISTON OIL CLEARANCE

(a) Subtract the piston diameter measurement from the cylinder bore diameter measurement. Standard oil clearance: 0.065 to 0.088 mm (0.0026 to 0.0035 in.) Maximum oil clearance: 0.088 mm (0.0035 in.)

• If the oil clearance is greater than maximum, replace all the pistons.

• If necessary, replace the cylinder block.

17. INSPECT PISTON PIN OIL CLEARANCE

(a) Using a caliper gauge, measure the piston pin bore diameter.

Piston pin bore diameter:

mm (in.)

A

20.006 to 20.009 (0.7876 to 0.7878)

B

20.010 to 20.012 (0.7878 to 0.7879)

C

20.013 to 20.015 (0.7879 to 0.7880)

(b) Using a micrometer, measure the piston pin outer diameter.

Piston pin outer diameter:

A

20.004 to 20.007 (0.7876 to 0.7877)

B

20.008 to 20.010 (0.7877 to 0.7878)

C

20.011 to 20.013 (0.7878 to 0.7879)

(c) Using a caliper gauge, measure the connecting rod small end bore diameter.

Connecting rod small end bore diameter: 20.012 to 20.021 mm (0.7879 to 0.7882 in.)

Mark

A

20.012 to 20.015 (0.7879 to 0.7880)

B

C

20.019 to 20.021 (0.7881 to 0.7882)

(d) Subtract the piston pin outer diameter measurement from the piston pin bore diameter measurement. Standard oil clearance:
