Hello All:
I was given a Fox .50? that was gummed badly with some type of dried oil. I disassembled the engine and cleaned the parts as best that I could. All went well until I installed the rear bearing. This bearing makes a noise and has a bit of drag when it is spun in the engine. Outside of the engine, the bearing sounds good but not perfect.
Perhaps I did not remove all of the "varnish" from the bearing. I boiled the bearing in dishwasher detergent, used an ultrasonic cleaner with the same strong detergent and soaked it in carb cleaner. Can I use a solvent other than water in an ultrasonic cleaner? If so, what works well? I have no idea as to how to clean the bearing other than soaking it in some type of aggressive solvent for a long period of time. Perhaps I can find a replacement bearing. What are your thoughts about running the bearing as it is?
Suggestions?
Tia,
