b) Apply threadlock to the bolt securing guide 7 to the front vertical tu14 and
tighten firmly, but take care not to distort or crush the tube.
This should be done at this stage as the bolt holding this bracket is not
easily accessible later.
Whilst the spacer should prevent crushing of the tube, it is better not to
rely on it. It is permissible for the spacer to remain slightly loose, as
under load it will still prevent excessive deformation of the tube.
Do not distort the tube.
c) Mount the U-brackets 5 to the lower cabin triangle tubes tu12
Note the use of a spacer sleeve in the tubes.
The studs should be long end downwards to mount the bottom of the
firewall and the front of the fuselage covering later.
If the bolt thread sticking out of the nut securing the U brackets to the
TU14 fouls the TU12 end file the end of the TU12 to provide clearance
d) Mount the steel diagonal-brace tu43 to the bottom of the stud through the port
tube. Use thin plastic washers 26 and steel washers 25 .
The other end of the brace will be attached to the rudder pedal mounts
later. The brace may be supplied attached to the mounts, have a look
under the packaging.
Thin plastic washers may be used to take up any slack between the
tubes and U-brackets.
