dowels, J 37085, to ease alignment of drive
gear to timing gear hub.
Figure 7-21 — Installing Drive Alignment Dowels
4. Install the fuel injection pump driven gear on
the timing gear hub so the screw holes in the
hub are centered in the gear slots/alignment
dowels.
Figure 7-22 — Installing Driven Gear
5. Install two driven gear capscrews in the
open holes. Install capscrews snugly to
remove clearance but allow relative motion
between hub and gear.
Figure 7-23 — Installing Driven Gear Capscrews
6. Remove the alignment dowels and install
remaining capscrews in the same manner.
7. Using hub rotation tool J 38740, rotate the
timing gear hub counterclockwise until
screws bottom in the ends of the gear slots
in the fuel injection pump driven gear. When
this happens, both lamps will go out.
Three different head sizes have been used for
the injection pump timing adjustment capscrews.
