GENERAL PROCEDURES
Cylinder Bore Taper
1. N0TE:The main bearing caps or lower
crankcase must be in place and tightened to
the specified torque; however, the bearing
shells should not be installed.
Measure the cylinder bore with an internal
micrometer.
Carry out the measurements in different
directions and at different heights to
determine if there is any out-of-roundness or
tapering.
If the measurement is out of the specified
range, install a new block or hone out the
cylinder block (if
aplicable/allowed).
