OK, it has gotten to the point of actually examining an engine and I need a little help.
I am in the dark on how we anchor a dial indicator to the crankcase and then spin the crank to check crank runout and axial endplay. I can imagine and invent methods, but if there are standard ways of doing so, I would rather do it the standard way.
A magnetic mount won't grab the aluminum case. Perhaps a steel fixture is fabbed up and bolted to the existing bosses? And the engine without a prop on the flange seems to make turning the engine difficult. Engine in question is a Lycoming IO-360.
So, please explain the process and pieces for this newbie to engine measuring. Photos are great too
