6.3 PROCEDURE FOR PILOT ASSEMBLY G-40/42
To perform the assembly of the G-42 pilot just follow the steps reported in the back disassembly procedure
forward starting with the assembly's headquarters, but would like to make two observations on two specific points
that must be evaluated thoroughly during the pilot reassembly.
1)
Pay attention to mount the seat (pos 46/48) and mobile (Pos 44/46), the seat of the hole should always be
installed in the opposite position to stud the mobile base, as illustrated below, otherwise the seat will not match
the shutter (pos 29/26).
2)
After mounting the seat (pos 46/48) in the mobile (Pos 44/46) is necessary to leave the perfectly aligned to the
mobile base of the hole headquarters in order to prevent the same into contact with the walls of the mobile base
during operation, adequate to accomplish this alignment procedure is:
2.1) After mounting the seat (pos 46/48) in the body (post 49/51) mount the lower and upper diaphragm
assembly and lock with nut (pos 35/32) and diaphragm support (pos 36/35).
2.2) With the assembled unit, turn the mobile base (pos 44/46) clockwise until it stops at the headquarters (item
46/48), with a pen make a mark on the diaphragm and body, turn again towards the mobile base anti-clockwise
until it stops again at headquarters (post 46/48), make a mark on the body following the marking already
performed in the diaphragm (pos 9/11), position the marking performed in the diaphragm between the two
markings done in the body, so we can assume that this centralized headquarters.
