SERVICE MANUAL
GENERAL
Section 1
assembly consists of a holder body, doweled nozzle
spacer, lower spring seat, pressure adjusting spring,
shims and a nozzle retaining nut.
The holder body contains a high pressure tubing
connection at the upper end, a high pressure fuel duct, a
leak-off duct and drain connection. The lower end is
counterbored to accept the pressure adjusting spring and
shims. The lower face is lapped to a fine surface finish
and contains two locating dowel pin holes. The lower
spring seat provides a seat for the spring and a contact
surface for the nozzle valve stem. The nozzle spacer
contains two locating dowel pins which locate the nozzle
radially to the holder body to insure proper spray
pattern orientation. Both faces of the spacer are lapped
to a fine surface finish to provide gasketless, high
pressure seals between the holder body face, spacer
faces and nozzle body face. The spacer also acts as the
nozzle valve stop. The cap nut clamps the nozzle and
spacer to the holder body.
Fuel flowing through the high pressure tubing enters the
nozzle holder and flows down the high pressure duct,
through the spacer duct and to the nozzle. The slight
fuel leakage between the nozzle valve and body enters
the spring chamber in the holder body and flows through
a return duct to a drain connection.
