Rudder Pedals - Part 2

Co-Pilots Pedals 
Connecting rods locate the co-pilot pedals
Located the pedals using the rod end as outlined previously, marked its center-line and installed the reinforcing plate to the underside of the floor plate. Both pedal plates had been drilled for fixing to the longeron previously. 

[Refer Pilots Floor Plate for installation notes]

Pop riveted the floor plate to longeron but not to bulkhead until skin is re-installed.

Fitted both the co-pilots pedal assembly's as outlined in Part 1 ensuring that both connecting rods are the same length. Lightly fix with lock nuts as the nose gear connections have to be installed before any final adjustments.


Checked for smooth operation - shimmed bearing gap as required.

Area washers are installed at each rod end to ensure they cannot escape in the event of a bearing collapse. 

Modification
Custom bolts were manufactured from M6 X 45 Unbrako screws. All bolt's where hand threaded to provide the required amount of plain shaft to suit each application and were to replaced all fully threaded bolts used in the pedal assembly's. Threads were trimmed to there correct length and polished using a plastic buff on a bench grinder to remove all sharp edges. 

Nylon or fiber washers install at brake pedal pivot's to adjust clearances to a minimum. 

All bolts were treated with Loctite 222 on assembly and nylock nuts installed as applicable.
