 Note. The pump camshaft contains an
over-center lobe which tends toprevent
the timing mark on the hub from re-
maining in line with its mating pointer.
These marks must be alined when in-
stalling injection pump driven gear and
retaining plate (fig. 77).
(5) Check engine timing before installing
fuel injection pump. The engine timing
is correct when the mark on crankshaft
damper and pulley assembly is alined
with the point er as shown in figure 66,
and when No. 1 piston is on the com-
pression stroke. For convenience, the
engine timing marks were alined before
the pump was removed. When engine
timing marks are not alined, rotate the
engine clockwise as viewed from the
front until timing mark on damper and
pulley assembly is alined with pointer,
