the injection pump. Carefully pull the pump
straight up out of the bore.
Be careful when an injection pump is disassem-
bled. Do not damage the surface on the plunger. The
plunger and barrel are made as a set. Do not put the
plunger of one pump in the barrel of another pump. If
one part is worn, install a complete new pump assem-
bly. Be careful when the plunger is put into the bore
of the barrel. When injection pumps and spacers are
removed from the fuel injection pump housing, keep
the parts together so they can be installed in the same
location in the housing.
