Piston Grading For 1994 Automotive
Applications Only
When rebuilding an engine with the original cylinder
block, crankshaft, and pistons, make sure the
pistons are installed 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.
