1. General
The two thrust-reverser half-cowl can be opened separately, using a hand pump. Opening of the thrust-reverser half-cowl provides access to the systems and components mounted in the engine core section.

Thrust Reverser C-Duct Opening - GSE Hydraulic Connector2. Description
The two hydraulic actuators are located between the pylon and the two half reversers.
Each half reverser is actuated by a single-acting hydraulic actuator. They are fluid supplied by a hand pump which can be connected to the connection box on the lower section of the forward frame.
The input power is transmitted from the pump through hard line tubes and a hose to hydraulic actuator.
A door hold-open rod, located on the engine mounted adapter ring assembly, is to be used with the door opening actuator.
The system is put to return to retract hydraulic actuators under thrust reverser weight action. The orifice of the hydraulic actuator chamber rectricts the fluid flow, limiting the rate of retraction of the hydraulic actuator rod.
The thrust reverser half doors can be opened to a 45 degrees position for engine removal. A placard at the door opening actuator connection point warns that the wing leading edge slat must be in the retracted position when the thrust reverser half doors are opened.
The thrust reverser half doors can be opened to 33 or 35 degrees position with the wing leading edge slat extended as follows:
PRE SB RA32078-32
The left and right half doors can be opened to 33 degrees position.
POST SB RA32078-32

3. Cowl Latch
Four tension hook latches along the lower edge of the cowls, maintain the reverser halves in the closed position. These latches are accessible without opening any access panel and can be ajusted without opening the C-ducts.

4. Adapter Ring
Two adapter rings are bolted to the inner and outer flanges of the engine fan frame. The adapter ring attached to the engine fan frame inner flange interfaces with a seal on the forward face of the thrust reverser inner duct. The adapter ring attached to the engine fan frame outer flange forms a V groove. A V blade installed on the forward face of the thrust reverser forward frame engages this V groove when the thrust reverser doors are closed.
