Cylinder Block Assembly: Testing and Inspection

Cylinder Bore Out-of-Round

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.

1. 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, hone out the cylinder block or install a new block.
