I have six IO520 steel cylinders with pistons for sale. (P/N 649166) When I bought my C310R, they were installed on my right engine, an IO520-M. All have a nice circular burn pattern on the exhaust valves. I had the unfortunate experience of my geared alternator eating up my crankshaft, when the alternator shaft failed. When overhauling the engine, I put six new Millennium cylinders on it. My thought was to have six spare cylinders to have in reserve. I just sold the 310, so these are available for sale. They have about 250 hours since overhaul. They were done by PennYann 7/2016. I have checked for cylinder AD’s that would apply, and can find none. The Eci AD came out 8/2016. None of these have the AEC65385 stamp. Eci pistons were used, and the cylinders are listed as “P15”. I have copies of the overhaul paperwork. All had good compression when removed, but do have some cylinder bore corrosion. I think if honed, and with fresh rings, they will give someone good service. Probably best sold to someone with a high time engine with tired cylinders. These IMO, could last you another 3-400 hours. I believe these will fit most IO520’s with the Permold case.

So these are definitely ECI cylinders?

Hi,
I think these are TCM cylinders that were overhauled by PennYann. They have Eci pistons. I didn’t want someone to think I was selling Eci cylinders that aren’t able to be used after they are removed. Just to be sure, I’m giving the buyer a 30 day period to evaluate the airworthiness.
Thanks,
VW
