Many thanks for your response. I’ve tried switch cleaner with the pot out of the yoke and in pieces, so I could see the track. I’ve never come across the term 90 degree before, but it is clearly marked on the pot. However, it has 300 degrees of movement, so I am clueless as to what this really means. All my Saitek Equipment is over 10 years old. The rudder pedal brake lever snapped a few weeks ago, but I’ve managed to fix that. I looked at AliExpress, but the disparity between photos and description made me doubt them as a company. I was hoping someone had done this repair and knew a reliable source of the components.
Thanks Again.
