9. When drilling crankshaft it is important to drill and install
the pin in-line with crank timing gear and oil pump drive
cam keyway to ease installation/removal of gear and cam.
Installing the pin in-line with keyway also provides proper installation of an aftermarket keyed dampener.

install drill fixture (Figure #3). Center fixture hole over extended keyway marks using a flashlight to
view through fixture holes.

debris from entering engine.
