I am now the owner (won't say proud because I haven't even seen it yet) of a 100 HP, Lycoming O235-C engine. Several years ago it was in a sprayer/duster and the pilot had a nose up and the crank flange is bent. Anyone ever heard of straightening a bent flange or will I have to replace the crankshaft. The person who GAVE it to me didn't know. He bought the engine some time back and then decided not to use it and sold it. The new buyer decided not to use it and gave it back -- so my friend could give it to me without losing anything. The rest of the engine should be in pretty good condition -- it didn't have much time on it when it crashed. Anyone ever hear of an O235 engine being used in a Piet. I love Lycomings. I had an O260 in the PA22 that I rebuilt but didn't have to do anything to the engine. They probably don't develop the power that a comparable Continental does, but they will run forever. I want to disassemble it and take the parts to an engine person to see if it's worth trying to rebuild. Anyone know how to disassemble a Lycoming? Jack, if it turns out that I can use it, there goes the harsh words you were going to use on me for using a Corvair. Anybody have an O235 overhaul manual I can buy cheap?

Congratulations, Charles for turning away from the Dark Side!I'm not terribly familiar with the O-235, but I have done some cylinder workon the O-320 on my RV-4. Lycomings are assembled differently fromContinentals, but the overhaul manuals are well written and easy to follow.You should be able to get an overhaul manual on ebay or just write toLycoming.Gene is right - no straightening of the crank should be attempted. There isan AD on Lycomings that require a tear down and inspection for ANY propstrike. In addition to replacing the crank you should replace the dowel pinthat keys the cam drive gear to the crankshaft, and inspect the gears forcracks.Lycomings run rougher than Continentals, but they will run rough a lotlonger than a Continental will run smoothly. I think you'll be very happywith it.Jack PhillipsNX899JP "Icarus Plummet"Raleigh, NC _____

Jack, do you have any idea what it might cost me to get that O235 running? ----- Original Message -----

Subject: Re: Pietenpol-List: Real Airplane EngineI am building with an 0235 C1B engine I plan to spent between 5 and 7000 on it by the time its completely rebuilt. I hope that helped. I have ben told that if the flange is bent you're into a new crank. Just what the shop has said. BTW mine suffered a minimal prop strikee with no damage to the engine. it set so long the internal corrosion took out the cam and tappets al the rest is good with no run out. Just a matter of the rings,beqarings,seals, bolts and nuts, oil pumpgears and gaskets at a little more then 3 k forthe parts as I recall. ignition is another story. Mince came with the Bendix shower of sparks mags and no box so I am planning on the slicks as the replacement set. JohnIn a message dated 3/6/2011 7:59:27 P.M.
