IMPORTANT:
It is very important that the pis-
tons in this engine are oriented correctly.
New pistons are stamped “EXH.” This marking
should be oriented to the exhaust side of the
block. As another reference, the splash bowl on
the dome of the piston will be located toward the
flywheel and opposite the exhaust port.
IMPORTANT:
It is also very important that the
connecting rods are installed with the alignment
dots and the diagonal oil hole facing up, toward
the flywheel.
