Today I took the rudder pedals apart in prep for installing them in the fuselage when it returns.
There is a good article on this at http://www.hangar9aeroworks.com/108Torquetube.html
Planning on blasting the pedals, but not the torque tubes as they are two piece and lubricated so they move to actuate the brakes. Don’t want any blast media in there. I will be painting the tubes once cleaned. the bearings are in decent shape and I will know more after the cleanup, but I may have to take the advice from the site above and replace with a similar bearing.
