(1)
Install the gear box (123) temporarily at longeron (116) with screws (119).
(2)
Measure the gap between the surface of the gear box (123) and the longeron (116) find the correct thickness of the laminated shim (115).
(3)
Remove the screws (119) and the temporarily installed gear box (116) from the longeron (116).
(4)
Remove as many layers of the laminated shim (115) as necessary to get the correct thickness.
NOTE : Make sure that the thickness of the laminated shim (115) is
____ one layer thicker than the measured gap. This is necessary because the thickness of the laminated shim (115) becomes smaller when it is compressed during the installation.
