Pull the tool and tappet through the cam bore and up into
the tappet bore.
If difficulty is experienced in getting the tappet to make the
bend from the trough up to the tappet bore, pull the trough
out enough to allow the tappet to drop down and align itself;
then, pull the tappet up into the bore.
After the tappet has been pulled up into position, slide the
trough back into the cam bore, and rotate it one-half of a
turn. This will position the round side of the trough up,
which will hold the tappet in place.
Remove the installation tool from the tappet.
