-position the crank journal at BDC
-install boots over the rod bolts
-make sure the rings are installed right side up
-check piston-to-cylinder wall clearance using Plastigage

Answer 1

-check piston-to-cylinder wall clearance using Plastigage. A technician is least likely to perform the step of checking piston-to-cylinder wall clearance using Plastigage when installing a piston/connecting rod into the cylinder block.

Step-by-step explanation:

When installing a piston/connecting rod into the cylinder block, a technician is least likely to perform the step of checking piston-to-cylinder wall clearance using Plastigage.

Positioning the crank journal at BDC is an important step as it ensures proper alignment and timing. Installing boots over the rod bolts helps to prevent any damage or interference. Ensuring that the rings are installed right side up is crucial for proper sealing and combustion.
