Hi all,
The fan in my 547 was running slow and taking a long time to run up to speed. I took it apart to find the bearings all gummed up with sticky greasy old oil. I've washed it all out with an appropriate solvent and now need to relube it. Is there a recommended oil to use? I have various grades available ranging from 3-in-1 to heavy EP90. I'm leaning in towards 3-in-1 or maybe Mobil-1 motor oil. There's no recommendtion in Stan Griffiths' book.
Any ideas or advice?
Thanks, Morris
