Fit the centring springs
The centring springs are
attached to the top of the 2
centre rudder pedals with
AN3-11A bolts and Bundy
tube spacers and then
anchored by chain links and
link tabs to the aluminium
bracket that is riveted to the
lower console – refer to the
photo at right for detail.
Place the aluminium bracket
over the console as shown
and connect the springs to the
middle position using
AN3-5A bolts and Nyloc nuts
and then apply a firm
rearwards pressure to the top
of the bracket until both
springs are under tension and
then drill and rivet the bracket
to the console, making sure that the bracket is vertical. Use 3 x 7/32” TLR rivets per side as
shown above.
Use pliers to bend the hooked ends of the springs so that the springs cannot easily or
accidentally be removed.
Adjust the spring tension by altering the position of the anchor bolts so that the nose wheel
will return to centre when there is no weight on the nose wheel (hold the tail down to do this
check). When adjustments are complete tighten the anchor bolts and nuts.
Fit the dust covers
The last step is to fit the rubber dust covers into place –
hold each cover so that it is square and level and fix it
in place by means of either contact adhesive or small
screws and washers.
The photo at right shows a dust cover fixed in place
with contact adhesive, alternately silicone sealer can be
used to hold the dust cover in place.
