15. INSPECT CYLINDER BORE
(a) Using a cylinder gauge, measure the cylinder bore diame-
ter at positions A and B in the thrust and axial directions.
Standard diameter:
88.500 – 88.513 mm (3.4843 – 3.4848 in.)
16. INSPECT PISTON DIAMETER
(a) Using a micrometer, measure the piston diameter at right
angles to the piston pin center line, 30.3 mm (1.193 in.)
from the piston head.
Piston diameter:
88.439 – 88.449 mm (3.4818 – 3.4822 in.)
17. INSPECT PISTON CLEARANCE
(a) Subtract the piston diameter measurement from the cylinder bore diameter measurement.
Standard oil clearance: 0.051 – 0.074 mm (0.0020 – 0.0029 in.)
Maximum oil clearance: 0.1 mm (0.0039 in.)
(b) If the clearance is greater than maximum, replace all the 4 pistons. If necessary, replace the cylinder
block.
18. INSPECT RING GROOVE CLEARANCE
(a) Using a feeler gauge, measure the clearance between
the piston ring and the wall of the ring groove.
Ring groove clearance:
0.030 – 0.070 mm (0.0012 – 0.0028 in.)
