Synchronize the Thrust Reverser Actuators [CFML]

TASK 78-31-41-820-801-A
Synchronize the Thrust Reverser Actuators

1. Reason for the Job
A. This task makes sure that all four actuators are correctly adjusted to have the same travel. When the actuators are synchronized, the translating cowl moves to the fully stowed and fully deployed positions without jamming or binding.
B. You must do this task each time you install an actuator, a sync shaft or a flex shaft.
C. This task starts with all the actuators installed and the sync shafts and over-the-top flex shaft removed.

NOTE: A sync shaft connects the right upper actuator with the right lower actuator. The over-the-top flex shaft connects the two upper actuators. A sync shaft connects the left upper actuator with the left lower actuator. Each shaft is installed in a tube.

NOTE: The two upper actuators are also known as the synchronized locking feedback actuators. The right lower actuator is also known as the synchronized manual locking actuator. The left lower actuator is also known as the synchronized non-locking actuator.

4. Procedure
Subtask 78-31-41-820-050-A

A. Synchronize the Thrust Reverser Actuators
(1) During this procedure, as you disconnect a tube or connector, install CAP - PROTECTION on all the openings to prevent contamination. Remove the CAP - PROTECTION immediately before you connect the components.
(2) Open the two latches at the bottom of the translating cowl. Make sure that the shear pins in the latch housing are disengaged from the mating receptacles in the opposite latch beam. You must open the other thrust reverser latches to be sure that the shear pins are disengaged.
(3) Synchronize the right half of the thrust reverser as follows:

Right Half of the TRAS

(a) If not done before, install the sync shaft (2) and the sync tube (3) on the right side of the thrust reverser as follows:
1 Lubricate the threads of the bolt (9) and the eight bolts (11) with lubricating oil turbine engine synt base (Material No.CPNCL00062) .
2 Put the P-clamp (10) in position on the sync tube (3).
3 Put the sync shaft (2) in the sync tube (3).

CAUTION: HOLD THE SYNC SHAFT IN THE SYNC TUBE. IF THE SYNC SHAFT FALLS OUT OF THE SYNC TUBE, DAMAGE TO THE SYNC SHAFT CAN OCCUR.

4 Put the sync tube (3) in position on the right side of the thrust reverser. Do not let the sync shaft (2) fall out of the sync tube during this step.
5 Loosely install the bolt (9) to attach the P-clamp (10) to the support bracket (8).
6 Loosely install the eight bolts (11) that attach the four saddle clamps (12) to the four support brackets (13).
7 Pull down the trombone fitting (4) and engage the upper end of the sync shaft (2) with the square hole in the right upper actuator (1).
8 Adjust the trombone fitting (4) and manually connect the coupling nut on the sync tube (3) to the right upper actuator (1).
9 Engage the lower end of the sync shaft (2) with the square hole in the right lower actuator (5).

(b) Use a DRIVE 3/8 IN - SQUARE to turn the right Manual Drive Unit (MDU) in the deploy direction until you hear a click. Do not TORQUE more than 0.5 m.daN (44 lbf.in). The click tells you that the actuator is fully deployed and the clutch in the MDU has slipped.
(c) Make sure that the right upper actuator (1) and the right lower actuator (5) are in the fully deployed position as follows:

CAUTION: DO NOT OPEN THE THRUST REVERSER MORE THAN 2 INCHES (51 MM). IF THE THRUST REVERSER HALVES ARE OPEN WHEN THE TRANSCOWL IS DEPLOYED, DAMAGE TO THE AIRCRAFT SLATS CAN OCCUR.
