I have a spare Franklin 165 with heavy case that I bought a couple of years ago out of a wrecked 108-2. It had a minor prop strike, but the flange dialed out and it had all log books, so I figured it was worth a chance. I just completed rebuild of 9366K, and the engine in it runs good, so I am not going to mess with it. The spare engine's crank was ground to .00010 at overhau 600 hours ago. Here's my dilemma: If I were going to use the crank, I would have it tested and certified, but as I'm not going to use it soon, I don't want to tie up the money having it certified, and then lie around for years. If I were to sell it, of course, the buyer would want it certified. Does anyone know what a certified crank like this is worth. I don't think the other engine parts would bring much as the crank is the most valuable part.
