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