C. Prepare to Install the QAD Coupling
S 214-008
(1) Do a visual check of the QAD coupling and the gearbox mounting pad mating surfaces.Make sure the surfaces are clean and smooth.
S 644-009
CAUTION: DO NOT PUT GREASE IN THE DOWEL PIN HOLES OR THE BOLT HOLES.
_______ DAMAGE MAY OCCUR TO THE GEARBOX DUE TO PRESSURE INCREASE WHEN THE BOLTS ARE INSTALLED.
(2) Apply a thin layer of oil (AMM 20-30-04/201) to these parts:
(a)
Around the gearbox holes where the mounting bolts enter.
(b)
The gasket side of the QAD coupling, between the mounting holes and the inner edge.
(c)
The QAD coupling tension bolt threads.

(3) Apply a thin coat of anti-seize to the threads and under the head of the mounting bolts.
D. Procedure
S 424-005
(1) Install the QAD coupling as follows:
(a) Install the gasket on the side of the QAD coupling that mates the gearbox mounting pad.
NOTE: A thin film of oil on the gasket will hold it in place.
____ Be sure the hole patterns in the gasket and the QAD coupling are aligned.
(b)
Put the QAD coupling on the gearbox. The word TOP should be at the top of the QAD coupling when looking toward the gearbox.
(c)
Attach the QAD coupling to the gearbox with 12 mounting bolts. Tighten the bolts to 276-300 Pound Inches.
(d)
Use a clean dry cloth to clean the excess anti-seize on the QAD.
S 424-006
(2)
Check the QAD coupling (AMM 24-11-03/601).
(3)
Install the IDG (AMM 24-11-01/201).

QUICK ATTACH/DETACH (QAD) COUPLING - INSPECTION/CHECK
_____________________________________________________
1. General_______
A. This procedure has two tasks:
(1)
The first task makes an inspection of the quick attach/detach (QAD) coupling.
(2)
The second task does a torque check of the QAD coupling tension bolt.
TASK 24-11-03-206-001
2. QAD Coupling Inspection (Fig. 601)_______________________
A. Equipment
(1) 900-24999 - Fixture, Simulated IDG Input Flange Inspection Plate, Hamilton Sundstrand, 4747 Harrison Avenue, P.O Box 7002, Rockford, IL 61125
B. Procedure
S 216-003
(1) Inspect the QAD coupling as follows:
(a)
Visually examine the QAD coupling mating surface for damage.
(b)
Visually examine the QAD coupling tension bolt nuts, and the tension bolt for damage.
(c)
Visually examine the inner surfaces of the QAD coupling clamp. Replace the QAD coupling if the wear is uneven.
(d)
Install the simulated IDG input flange inspection plate or the IDG in the QAD coupling.
