CYLINDER BLOCK (Contd)
CLEANING AND INSPECTION (Contd)
10.
Inspect cylinder liner counterbore of cylinder block (10) for dirty or rough edges.
NOTE
Counterbore diameter must be measured in liner press fit area
0.100 in. (2.54 mm) maximum below deck. Repair and shim
cylinder liner counterbore if the following conditions are not
met.
11.
Using engine block counterbore tool, measure inside diameter and depth of counterbore at four
equally spaced positions. Difference in measurement around circumference must not exceed 0.001
in. (0.0254 mm).
NOTE
When checking cylinder liner protrusion, ensure shim(s) and
cylinder sleeve correspond to cylinder being inspected as tagged
during removal.
Cylinder sleeve shims are available in the following
thicknesses: 0.007 in. (0.178 mm), 0.008 in. (0.203 mm),
0.009 in. (0.229 mm), 0.020 in. (0.508 mm), 0.031 in.
(0.787 mm), and 0.062 in. (1.575 mm).
Cylinder liner counterbore depth is 0.412 in. (10.465 mm).
12.
Using depth micrometer, measure depth of cylinder sleeve counterbore of cylinder block (11) and
outside flange of cylinder sleeve (1) for corresponding cylinder. Subtract difference to determine
amount of shims and/or depth of counterbore cut.
