Anyone know the diameter of a normal sized Lycoming 76220 thru stud or have one around they can mic?
There seems to be a previous attempt to repair my thru stud leak and I want to know if I have an oversized (76220 P01) stud installed. Theres no stamp on cylinder pad but there's also no record of a leak repair attempt in logbook.
Thru bolt bore was measured at .5007, and my thru bolt is .5013 which seems like a normal thru bolt diameter considering the need for the .500x20 threaded end to pass through easily.
Just wondering what oversized stud to buy to do SI 1290.
Thanks!
