Injector
After an injector tube has been installed
tube
in a cylinder head, it must tube be finished in three
(reaming)
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 injector 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.
