I have been looking for a little bit now and can not seem to come up with a source for an overhaul DVD or video of the Lyc IO-540. The closest I can find is for the IO-360. Anyone know of a source for the IO-540 or will the IO-360 one do? Other than 2 more cylinders I don't think the innards are going to be much different. Also a question for the experts out there. My engine had a mild prop strike and the crank flange dials .008". Am I going to be able to have this crank overhauled provided everything else is OK or does the runout automatically trash it? The Lyc serviceable limits in the manual give a .005 limit. I am just wondering if the crank can be brought back into limits by overhaul/machining or is .008 going to be OK? And unfortunately, the crank for this engine does not fall under Lycomings SB569A for the $2000 replacement. The engine serial number falls under the SB, but the crank # does not. The engines here in the shop and I am a ways off from needing it, but I am just trying to form a plan to get things going on it. Thanks for any help folks!
