Piston Grading For 1994 Automotive Applica-
tions Only
When rebuilding an engine with the original cylinder block,
crankshaft, and pistons, make sure the pistons are in-
stalled in the original cylinder. If replacing the piston(s),
make sure the replacement piston(s) are the same grade
as the original piston. If a new cylinder block or crankshaft
is used, the piston grading procedure must be performed
to determine the proper piston grade for each cylinder.
Install the connecting rod/piston assembly into the No. 1
cylinder without the rings installed. Make sure the word
``Front'' on the top of the piston is toward the front of the
cylinder block.
NOTE: The connecting rod bearing shells must be installed
in the original connecting rod and cap.
Install the upper bearing shell in the connecting rod with
the tang of the bearing in the slot of the connecting rod.
Use clean lubricating oil to coat the inside diameter of the
connecting rod bearing shell.
