backing out the capscrews (Item C.).
5.
Remove the intake manifold (Item

6. Disconnect the nozzle pressure and return
lines (Items 8 and 9 respectively).
7. Remove rocker arms
with

the head away without
wedging with tools inserted between mating
surfaces
to

If
the cylinder head is removed with the nozzles
installed, care must be taken not
to
damage the
latter which project above the surface, or remove
them first
as
a precautionary measure.
