REFLECTOR: Engine back together

[Laurence Coen]

John,

I applied a very thin coat of Permatex to one surface and then laid the silk on.  The thread goes by bolt holes toward the inside of the engine.

Larry,

I'm hearing different methods.  One is coating the entire mating surface.  Another is coating only the silk thread.  What did you do?

  Hylomar

  That's what I used also... You can get it at your local auto parts store...

  Robert Still of Southern Aero and I put my Franklin together about a 2 months ago. We did it by the book, only using sealant where called for. Hylomar is the preferred sealant. Silk thread was applied where called for at corners where multiple surfaces meet. My recommendation is to stick to the book.

  Geoff,

  I'm getting ready to reassemble my Franklin engine.  Did you use silk thread on the case?  When I disassembled, I saw no sign of any silk thread.  Did your engine have silk thread when you disassembled?  Is it easy to spot?  A friend has recommended a sealant used on motorcycle engines and I'm considering that.

  Thanks,

  John

  Guys, 



  Well, it took a couple months, but my engine is back hanging on my plane.  This time completely rebuilt, all shiny and new(ish).  For those who haven't kept up, I bought a 500hr engine that I found needed an overhaul after first taxi.  I pulled the engine off my plane, brought it back home, dissembled it and sent everything out for rebuild/inspection.  A few weeks ago, everything arrived back and over the last couple weeks I put it back together and on Friday mounted it back on the plane.  I haven't turned it over yet, still a few things to plumb and connect.  Should be sometime this week. 



  Anyway, I took lots of pictures during the reassembly process and put together a pretty comprehensive post describing the process.  Anyone considering rebuilding their Lycoming might find it useful.
