Objectives of this task:
To fit the rudder pedals and steering links to the aircraft, and fit the rudder cable to the rudder
pedals and set the deflection of the rudder.
Materials required:
Card # J3 “
Rudder
”
Card # J19 “
Noseleg
” for the steering yoke
Fit the pedals
The rudder pedal assembly will be fitted to 3 sets of bearing blocks, 2 on the moulded floor
mounts and 1 on the lower front of the console. Sit the pedals in the lower mounting blocks on
the mounts and clean the front and back holes in the mounts with a 3/16” drill. There are
captive nuts in the centre holes in each mount so do not drill any centre holes.
Apply a thin layer of grease to the half-round cutouts in the upper and lower rudder pedal
blocks and then fit the rudder pedals into place in the lower blocks. Seat the pedal assemblies
in the blocks and fit the upper blocks and clamp plates and secure with an AN4-25A centre
bolt to each block to hold it in place. Check for minimal side-to-side movement.
Place a flat washer under the head of each bolt.
Now fit the bottom clamp plates in place inside the floor mounts one at a time: start with the
front AN3-25A bolt and Nyloc nut – the front nut can be awkward to fit but if it is super glued
to the plate then the plate can be held in place and the bolt can be threaded down into it.
Fit the rear AN3-25A bolt and Nyloc nut all as shown at right.
When all bolts and nuts have been fitted, tighten each nut to safety
and then tighten the centre bolts down firmly.
Check for free fore and aft movement of the rudder pedals.
It may be necessary to adjust the tension on the bolts slightly if
the pedals are binding.
Fit the ¼” UNF Allen head cap screws through the pedal travel
stops beside the pilot‟s side right rudder pedal on the rear bar and
fit ¼” UNF plain nuts behind. These will be set later in this task.
