(3) Plunger Stop Screw Adjustment
(a) It is necessary to understand the operational
features of the pressure control reversing propeller
system to correctly locate the plunger stop screw
location of the pressure control unit.
1 In the Description and Operation chapter, the
section 1.C.(4) discusses setting the Pressure
Control Unit to a pressure attenuation value
which will be performed by the plunger stop
screw.
(b) Refer to the Description and Operation chapter of
this manual for construction, hardware description,
and operation.
1 Careful reading and understanding of the
section “Propeller Beta (Reverse) Operation” in
the Description and Operation chapter of this
manual is required.
2 The section 1.D.(7)(a) addresses the feature of
fixed oil pressure attenuation
that is performed
by correct location (adjustment) of the plunger
stop screw.
(c) The propeller control oil pressures that are shown
in Figure 2-3 “Oil Pressures - Pressure Control
Reversing Propeller” in the Description and
Operation chapter of this manual
are reproduced
with some additional information as Figure 3-16 in
this section.
1 The oil pressure chart in Figure 3-16 will be used
to help understand how to determine where
to locate the plunger stop screw to obtain the
correct fixed oil pressure reduction
for governed
propeller operation.
