6. INSPECT PISTON OIL CLEARANCE

a. Measure the cylinder bore diameter in the thrust direction.

b. Subtract the piston diameter measurement from the cylinder bore diameter measurement.

Standard oil clearance:

0.040 to 0.062 mm (0.00157 to 0.00244 in.)

Maximum oil clearance:

0.385 mm (0.0152 in.)

If the oil clearance is more than the maximum, replace all the pistons. If necessary, replace the
cylinder block.

7. INSPECT PISTON PIN OIL CLEARANCE

a. Check each mark on the piston, piston pin and connecting rod.

Maximum oil clearance:

0.015 mm (0.000591 in.)

If the oil clearance is more than the maximum, replace the piston and piston pin as a set.

e. Using a caliper gauge, measure the inside diameter of the connecting rod bush.

8. INSPECT CONNECTING ROD SUB-ASSEMBLY

a. Using a rod aligner and feeler gauge, check the connecting rod alignment.

1. Check for bend.

Maximum bend:

0.05 mm (0.00197 in.) per 100 mm (3.94 in.)

If the bend is more than the maximum, replace the connecting rod.
