3. Remove installing
tools.
5. Injector
After an injector tube has been in-
tube
stalled in a cylinder head, it must
(reaming)
be finished in three operations:
First, hand reamed, to receive the
injector body nut and spray tip;
second, spot faced to remove excess
stock at the lower end of the in-
jector tube; and third, hand reamed
to provide a good seating surface
for the bevel or the lower end of
the injector nut. Reaming must be
done carefully and without undue
force or speed so as to avoid cut-
ting through the thin wall of the
injector tube.
NOTE
The reamer should be turned in a clockwise direction only - both
when inserting, and when withdrawing the reamer - because
movement in the opposite direction will dull the cutting edges of the
flutes.
