the engine as the fuel injection pump
(Figure 6-93, (1)) and the embossed mark
(Figure 6-93, (3)) cast into the connecting
rod beam will face the flywheel end of the
engine (Figure 6-93, (5)).
4. Carefully reinstall the piston and rod assembly.
Be sure the match marks (Figure 6-93, (4))
stamped into the connecting rod and cap are
facing the fuel injection pump side of the
cylinder block, and the piston identification
mark (Figure 6-93, (2)) stamped into the piston
top is facing the camshaft side
(Figure 6-93, (6)). The embossed mark cast
into the connecting rod beam (Figure 6-93, (3))
will be facing the flywheel end of the engine
(Figure 6-93, (5)).
