2 Figure 2-2, “Pressure Control Reversing
Propeller System” in the Description and
Operation chapter of this manual
is a simplified
representation of the pressure control reversing
propeller system and does not show some detail
and components.
a A more accurate representation of the parts
involved with the minimum oil pressure
adjustment is shown in Figure 3-14 or
Figure 3-15.
(1) If installing a pressure control unit that
does not have a plunger stop, pivot
point (bracket), or control lever, refer to
Figure 3-14.
(a) These pressure control units still
require these features and the
customer or airframe manufacturer
must provide these features or
parts.
(2) If installing a pressure control unit with
the plunger stop, pivot point (bracket)
and lever incorporated into the Hartzell
Propeller Inc. supplied pressure control
unit, refer to Figure 3-15.
3 A control lever has been introduced to permit the
pilot to pull on a cable and push the plunger into
the pressure control unit body.
a The plunger compresses the pressure
relief compression spring that resists the
movement of the plunger into the pressure
control unit body. Refer to Figure 2-2,
“Pressure Control Reversing Propeller
System” in the Description and Operation
chapter of this manual.
