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 injec-
tor 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 cutting through
the thin wall of the injector tube.
