Cylinder Bore

Cylinder Bore Taper

1. NOTE: 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 applicable/allowed).
