INSPECTION OF CYLINDER BLOCK
INSPECT CYLINDER BORE DIAMETER
HINT: There are three sizes of the standard cylinder
bore diameter, marked
"I", "2" and "3" accordingly. The
mark
is stamped on the lower left rear of the cylinder
block.
Using
a cylinder gauge, measure the cylinder bore diameter
at positions A, B and C in the thrust axial directions.
Standard diameter:
2L-T STD mark "1" 92.000 - 92.010 mm
(3.6220 - 3.6224 in.)
STD mark "2" 92.010 - 92.020 mm
(3.6224 - 3.6228 in.)
STD mark "3" 92.020 - 92.030 mm
(3.6228 - 3.6232 in.)
3L STD mark "1" 96.000 - 96.010 mm
(3.7795 - 3.7799 in.)
STD mark "2" 96.010 - 96.020 mm
(3.7799 - 3.7803 in.)
STD mark "3" ,96.020 - 96.030 mm
(3.7803 - 3.7807 in.)
Maximum diameter:
2L-T STD 92.23 mm (3.631 1 in.)

mm (3.6508 in.)
3L STD 96.23 mm (3.7886 in.)

mm (3.8083 in.)
If the diameter
is greater than maximum, rebore all four
cylinders. If necessary, replace the cylinder block.
INSPECTION OF PISTON AND CONNECTING
ROD ASSEMBLIES
1.
INSPECT PISTON DIAMETER AND OIL CLEARANCE
HINT: There are three sizes of the standard piston dia-
meter, marked
"I", "2" and "3" accordingly. The mark
is stamped on the top of the piston.
(a) Using a micrometer, measure the piston diameter at
right angles to the piston pin center line, the indi-
cated distance from the piston head.
Distance:
2L-T 58.27 - 58.33 mm (2.2941 - 2.2965 in.)
3L 56.27 - 56.33 mm (2.2153 - 2.2177 in.)
