Spent some time cleaning up some landing gear parts and also one of the aileron servo pushrods. 40+ years of dust and dirt needed to be removed. The rod end bearings on the servo pushrods are screwed onto their tabs with metric caps screws and locknuts and with brass washers. A little bit of elbow grease and metal polish and those brass washers look real pretty again. I removed the rust from the lock nut by having it sit overnight in a small dish of Evapo-Rust. Available from the aircraft section of Lee Valley. ;-)
The bearings in the rod ends are really neat. The outer ring has two groves in it that allow to ball to be removed and everything cleaned. I didn't take a picture of that detail but I found an image on the internet of a rod end with similar grooves. I've never seen this style before. Very helpful for cleaning and lubing.
