 |
|
I purchased a used Lycoming IO-540-C4B5 narrow deck engine used from a Piper Aztec that was being parted out for use on my RV-10.
It had 982 hours on it and had chrome cylinders. Early on in my flight testing I replaced five of the six cylinders with new cylinders.
So now I have five chrome cylinders in the hanger and am wondering what to do with them. I think they may have value for being overhauled? Any ideas on what or where I should look for getting them out of the hanger?
On a separate note, I also have a set of the larger hole engine mounts for this engine as well. Don't need them at this point either. What to do with them?

With a little ingenuity you could make lamps out of them. Chromed cylinders had enough hours of operation to not meet standard dimensions. Then they were chromed back to standard.So they have several thousand hours on them, and the head and cylinder have been demated at least once. While this was standard practice 30 years ago, it has been at least 20 years since chroming was common, especially after Superior and ECI got PMA for new cylinders, which forced Lycoming to compete on price.
I would not be interested in a chrome cylinder, unless I needed it to ferry a broken engine from Timbuckerootwo to where parts were available.
A friend had chrome cylinders on IO-360 in RV-8 that the chrome started flaking off, and CHT went very quickly to 500. His 50 hour since overhaul engine is getting a fresh teardown.

Sounds like the cylinders may be headed for the metal recycling bin. Oh well.
Thanks, Jim C
