When cutting the necessary holes through the firewall for the various cables, keep them to a
minimum size and use a suitable method of sealing around the cables after they are in place.
Having positioned the servo motor, mark out the mounting holes. Fit two MS21047-4 anchor nuts on
top of the tunnel, using TAPK33BS rivets. The unit is mounted with two spacers on each AN4-17A
bolt, one W14 spacer, and one shorter spacer made by cutting a W14 in half.
Turbo control unit
This unit is mounted vertically on firewall on the cabin side, in the position shown in figure 2.
The four mounting bolts pass through the firewall with the nuts in front of it. Since the thread length
of the bolts is rather short it will be necessary to make the appropriate part of the firewall thinner.
Using a 20 mm (3/4") hole saw, carefully drill through the forward skin and foam only. Bond
NAS1169C10 Tinnerman washers into the recess with flox, ensuring that the recessed face of the
washers is kept clear of the flox. Mount the unit with spring washers and M4 nuts.
