When correctly assembled, the piston
identification mark (Figure 6-132, (2)) stamped
into the top of the piston will be on the same side
of the connecting rod as the match marks
(Figure 6-132, (4)) stamped into the connecting
rod and connecting rod cap.
When installed in the cylinder, the piston
identification mark (Figure 6-132, (2)) stamped
on the top of the piston must face the fuel
injection pump side (Figure 6-132, (1)) of the
engine and the embossed mark on the
connecting rod (Figure 6-132, (3)) must face the
flywheel end (Figure 6-132, (5)) of the engine.
