CYLINDER BLOCK INSPECTION
id011000507200
1. Measure the cylinder block for distortion in six
directions as shown in the figure using a straight
edge and feeler gauge.
•
If it exceeds the maximum specification,
replace the cylinder block.
Maximum distortion, head gasket side of the
cylinder block
0.10 mm {0.0039 in}
2. Measure the cylinder bore diameter using the
cylinder gauge. The measurement position is in
the X and Y directions at a point
43.9 mm {1.73
in}
below the top surface of the cylinder as shown
in the figure.
•
If it is not within the specification, replace the
cylinder block.
Standard cylinder bore diameter
89.000—89.030 mm {3.5040—3.5051 in}

OIL JET VALVE INSPECTION
id011000505900
1. Apply compressed air to oil jet valve A and verify
that air passes through oil jet valve B.
•
If air does not flow, replace the oil jet valve.
•
If there is air flow with air compressor of less
than
180 kPa {1.84 kgf/cm
2
, 26.1 psi}
,
replace the oil jet valve.
Oil jet valve opening pressure
180—220 kPa {1.84—2.24 kgf/cm
2
, 26.2—
31.9 psi}

PISTON INSPECTION
id011000502100
Caution
•
If the piston is replaced, replace the piston, piston pin, and the snap ring as a single component.
1. Measure the piston outer diameter using the
micrometer. The measurement position is
8.0 mm
{0.31 in}
from the lower end of the piston (area
with no coating on the piston skirt) and in the
thrust direction.
•
If it is not within the specification, replace the
piston.
Standard piston outer diameter
88.965—88.995 mm {3.5026—3.5037 in}
2. Measure the cylinder bore diameter. (See 01-10-
32 CYLINDER BLOCK INSPECTION.)
