Questions and observations. Why is sealant not applied to the saddles on the forward, center and rear webs of the crankcase halves on Lycoming engines-? Sealant is only applied to the parting surfaces around the periphery of the crankcase halves on Lyc. engs. Continental engines apply sealant to the forward, center and rear web parting surfaces. Since there is very slight movement between the case halves parting surfaces in the center of the engine, metal fretting sometimes occurs as well as oil ingression between the parting surfaces which eventually means metal wearing against itself and torque being lost on the thru bolt nuts. Then it is just a matter of time for having to do a premature engine disassembly. On another note, Lycoming engines have their camshaft mounted above the crankshaft which means no oil drip effect from the crankshaft on to the camshaft which results in premature rusting of the camshaft lobe(s) and lifter face(s) if the engine sits inactive for a period of time. Continental engines mount their engine camshafts below the crankshafts and are less prone to rusting of cam lobe(s) and lifter face(s). Having to remove the propeller and starter ring gear on a Lycoming engine to change an alternator belt is a bad design while this is not necessary on most Continental engines since they mount their starters and alternators on the accessory drive case meaning that no drive belt is required.
I’m getting ready to overhaul mine, it’s an O360 A4M. How did you crate your crankcase for shipping? That’s my next step. My plan is to have all of the lower end components (bearings, conn rods, tappets, etc ready and have a professional assemble everything.
There's no set way to crate the case, but I used a heavy cardboard box outside with heavy cardboard inside. They won't provide any box for it specifically. I'd use those internal end caps to ensure nothing can be crushed. Insure it well. That will prevent most mishandling. I'm new to this as you know. I wish you well on your engine project and I'm glad my video helped you.
@@michaelbradford2816 from your other videos t looks like you’re in Northern California-I’m in the foothills outside of Sacramento. I spoke to an engine guy up your way about a year ago about assembling the lower end for me and was was receptive to the idea
Hello gentlemen please don’t do this again since you are not A certified mechanic so please remember this engines means your life to you in the sky even though this is not the right way to disassemble the engine ….. It's not the engine of your car in the garage, and if you find a fault while driving, you can pull over to the side of the road and fix it. Fly safe
So, apparently you didn't hear everything I stated across several videos? The parts will be checked and reassembled only by a certified engine rebuilding company. Since you seem to know a lot suddenly about correct disassembly, perhaps you'd put that into your own video and offer that to all? Confusing car engines with this helped no one as far as I can determine. It was a very poor analogy. Did you get any exposure to aircraft at all?
