If the oil clearance is greater than maximum, replace all the 4
pistons and rebore all the 4 cylinders. (See page EM–104) If
necessary, replace the cylinder block.

Using solvent and a brush, thoroughly clean the piston.
INSPECT PISTON AND CONNECTING ROD
Inspect the piston oil clearance.
(1) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, 20.5 mm
(0.807 in.) from the piston head.
Piston diameter:
Mark "1" 86.815 – 86.825 mm (3.4179 – 3.4183 in.)
Mark "2" 86.825 – 86.835 mm (3.4183 – 3.4186 in.)
Mark "3" 86.835 – 86.845 mm (3.4186 – 3.4190 in.)
87.315 – 87.345 mm (3.4375 – 3.4387 in.)
(2) Measure the cylinder bore diameter in the thrust
directions. (See step 2)
(3) Subtract the piston diameter measurement from the
cylinder bore diameter measurement.
Standard oil clearance:
0.175 – 0.195 mm (0.0068 – 0.0076 in.)
Maximum oil clearance: 0.215 mm (0.0085 in.)
