(a)
Using a micrometer, measure the piston diameter at right angles to the piston pin center line, 23.5 mm (0.925 inch) from the piston head.
Piston diameter:
STD
Mark "1": 86.850 - 86.860 mm (3.4193 - 3.4197 inch)
Mark "2": 86.860 - 86.870 mm (3.4197 - 3.4201 inch)
Mark "3": 86.870 - 86.880 mm (3.4201 - 3.4205 inch)
O/S 0.50: 87.350 - 87.380 mm (3.4390 - 3.4402 inch)
(b) Measure the cylinder bore diameter in the thrust directions.
(c)
Subtract the piston diameter measurement from the cylinder bore diameter measurement.
Standard oil clearance: 0.14 - 0.16 mm (0.0055 - 0.0063 inch)
Maximum oil clearance: 0.18 mm (0.0071 inch)
If the oil clearance is greater than maximum, replace all the 4 pistons and rebore all the 4 cylinders. If necessary, replace the cylinder
block.
NOTE (Use new cylinder block): Use a piston with the same number mark as the cylinder bore diameter marked on the cylinder block.
