Remove the auxiliary rudder stops (two bolts) to eliminate the possibility of the flange of the bellcrank on the rudder bars catching on the bolt heads and locking the system.

Removal of the fairing which forms a tunnel along the floor from the seat to the pedals is necessary for access to the bolts.
