1-7. Fuel Shutoff Rod Assembly or Solenoid
Assembly.
The fuel shutoff rod assembly (D, fig. 1-
13) or timing
window cover solenoid shutoff
assembly (E, fig. 1-13) is attached at the hydraulic
head timing window. When the fuel shutoff
rod is
pulled to the rear, or the solenoid is actuated, it
engages the fuel control
unit (B, fig. 1-13) or the fuel
control unit (B, fig. 1-13),
and shuts off the fuel.
1-8. Hydraulic Head Assembly.
NOTE
The key letters shown below in parentheses
refer to figures 1-14, 1-15, 1-16, and 1-17.
a.
The hydraulic head assembly consists of the
hydraulic head (S), fuel plunger (U), plunger sleeve
(R), plunger drive gear (P), fuel delivery valve (V),
plunger inner spring (K), and other related parts.
b.
The hydraulic head has a centrally ground and
lapped bore into which the fuel plunger fits. It is
counterbored and threaded at the upper end for the
plunger bore screw (T). Six discharge passages
extend symmetrically from the plunger bore and
meet six vertical outlet passages. The fuel delivery
valve is located in the head and held by a spring and
the delivery valve screw (W). A passage from the
