ASSEMBLY
Description
Each cylinder has a nozzle to ensure proper
delivery of fuel that is metered and timed by the
injection pump. The nozzle is positioned at the
lower end of the nozzle holder.
The nozzle holder is positioned vertically in the
cylinder head and centered in the cylinder
between the four valves. The nozzle fuel inlet
tube is inserted through the side of the cylinder
head and the tapered end of the inlet tube seals
the area between the tube and the nozzle holder.
The tube is secured in position with a sleeve nut.

Installation
1. Insert a nozzle holder gasket in the bottom
of the nozzle holder hole. Refer to
Figure 6-61. Make sure the washer-type
gasket is lying flat in the bottom of the nozzle
holder bore.
An alternate method of installing the washer-type
gasket is to hold it in place on the bottom of the
nozzle with a small dab of grease instead of
placing the washer in the hole.
