Fit the rudder cable bracket clamp
Fit a rod end to the rudder cable: thread it on to half the thread depth. The total cable travel is
80mm: pull the inner cable all the way out and make a mark at 40mm from the outer cable
then push the inner cable in to that mark. This puts the cable at the centre of its travel.
Fit the rod end to the rudder arm with a bolt.
Secure the rudder in the „5mm right of centre‟ position on the template, then hold the rudder
cable horizontal and mark the location of the locating groove in the outer cable.
Hold the cable clamp in place and drill a 3/32” pilot
hole into the fin through each hole in the clamp,
then check the holes from the back through the
access hole (as pictured at right) – there needs to be
enough room above the top hole and below the
bottom hole to fit the head of the bolt in place.
Make any vertical adjustments that may be required
then drill to 3/16”. Test fit the cable clamp: feed the
bolts from the inside and through the side of the fin,
then place the angled cable clamp packer against
the side of the fin with the wider part of the packer
to the rear of the aircraft, then the cable clamp shim
and finally the cable clamp. Secure temporarily
with plain nuts – final assembly will require Nyloc
nuts.
Test the movement of the rudder and rudder cable: make sure that the rudder can be moved to
each stop by use of the cable without any binding.
Remove the rudder cable fittings and the rudder and set aside for painting, put all hinge pins,
hinge pin retainers and rudder cable fittings into a labelled container for reassembly after
painting has been completed.
This completes the
