Dave ________________________________ Message 4 _____________________________________ Time: 08:21:27 AM PST US Subject: Continental-List: Re: A-65 rebuild From: "Tommy Walker" my replies aren't getting posted to Matronics, so here's what I wrote: Hi Dave, I have a very limited background working on engines and such as a young man. On Ebay, you can find a Continental Overhaul Manual for your engine. The last one I saw went for about $20.00. You can also get everything about the engine on one CD for a couple of dollars on EBay. It has the manual, Service Bulletins, ADs, etc. It pretty much has everything you need to know to tear down, inspect and rebuild your engine. We took ours apart and sent the case, crank and cam to Aircraft Specialties Services in Tulsa (www.aircraft-specialties.com) for inspection. I'm supposed to take the cylinders to a place in Newnan, GA next week. The problem I've had so far is how to properly disassemble the engine. I have a friend who has lots of experience rebuilding a/c engines and he gave me a lot of valuable pointers, plus advice on what to have checked and who to send it to. I'm sure when it comes time to put everything back together, my friend is going to save me from a major catastrophe. We plan to put the engine in a Kitfox Super Sport. I'm also working on getting it ready to do the first mount of the wings, plus looking for a new hangar since our home airport closed last summer. I'm building the plane in my garage, but when we start putting the wings on, I'm going to have to put it in a hangar somewhere. I live in Anniston, AL. Here's a link to our website.

Thwing" Subject: Re: Continental-List: A-65 rebuild There is probably plenty of help when you are ready for it, but please don't ask something like: "Please send me everything you know about rebuilding small Continentals". No one has time to write novels. If you ask one or two questions at a time, you will probably get plenty of answers and advice. Two weeks ago, we had engine start of a very thorough OH of a O-200 we did for our first issue C-150. Everything good so far. Go slow, be thorough and methodical and don't do anything that you wouldn't want to explain to a IA. I'll ask the first question of Dave & Tommy: What cylinders do you intend to use? Rebuild yours, of buy new?

Right? I now see that my post got posted twice. I sent it via email and when I checked it hadn't been added so I copied it and pasted. Just deleted the first reply. Cylinders.... We hope to use our cylinders. It all depends on how the inspection goes. If I could find a good deal on cylinders like I did on new ones from TCM a few years ago, I would go for it. But if these check out we will use them. They are steel cylinders with no oversize. The engine had 240 hrs SMOH when it had a prop strike. We are waiting to hear about Crank and case.... -------- Tommy Walker N8701 - Anniston, AL Read this topic online here: http://forums.matronics.com/viewtopic.php?p=332905#332905 ________________________________ Message 9 _____________________________________ Time: 09:12:34 AM PST US From: SENTUCHOWS@aol.com Subject: Re: Continental-List: Re: A-65 rebuild I would also like to use the cyls I have. I bought 3 A-65's with the idea of building one good engine. I realize some things will have to be rebuilt or replaced. Have one engine torn down and have some good pieces. It was an a-75 with the waffle pistons. I have one set of working Bendix SF4 Mags And a completely rebuilt Stromberg carb. One engine has a couple chrome cyl's on it. I have to Mic the inside of the cyl's and see what I have. If over Standard bore, I can bore out the cyl's out .015. New pistons and rings required. Parts for that about $500????? I don't have any idea what the bore job would cost.

Thwing" Subject: Re: Continental-List: Re: A-65 rebuild Hello Tommy: Yes, I am on most of the ZA lists. We have corresponded before. The following contains many facts and a lot of my opinions. It is worth exactly what you are paying for it. If you have a O-200 that is used in a certified aircraft, with original Continental cylinders identified by casting numbers, they are subject to cylinder head cracking. O-200's specs call for ignition timing of 28 degrees BTDC and a redline of 2800 rpm. Because of the head cracking problem, there is a three decades old AD that requires the timing to be retarded to 24 degrees BTDC. This decreases horsepower in an effort to alleviate the cylinder head cracking. Is this cracking a result of cylinder head design geometery or the fact that these cylinders were designed to run on 80 octane fuel which is no longer available? I can't answer that. I do know that the cylinder head cracking is real and does occur often. These same cylinders are used on most the small Continental 4 cylinder engines as well as the C-145/O-300 six cylinder engines. As the O-200 is the only one that has the 2800 RPM redline, this AD doesn't apply to the other engines as they don't turn as fast. Does that mean turning at a lower RPM won't cause head cracking? That has not been my experience. Two years ago, we overhauled a C-145 six cylinder for our flying club 1958 C-172. The removed cylinders, along with several cylinders offered to us for sale "for rebuild" in total, eleven had cracked cylinder heads. These can all be rebuilt, the heads welded etc. but what do you have then? Regardless of rebuild, they are still subjec to the AD in a O-200. How long will they last? Our decision was to buy modern designed ECI cylinders whch are engineered to run on 100 octane avgas. In experimental use, you don not have to comply with this AD, but does that make any difference in reliability? Continental now produces a newer design cylinder that relieves one from the AD for the O-200. I have been told, that the ECI cylinders have valve rotators installed and the Continental cylinders do not. I don't know if that is true. Again, this AD does not apply to other engines like the A-65. The decision then, is how does the cylinder rebuild price, of the older design, compare with buying new design cylinders? Our decision was based on two things: 1. To buy a cylinder of a newer design to avoid head cracking, and eliminate the AD to allow a full 100 HP. 2. To buy a cylinder designed to use 100 octane avgas. There's some info. I'm sure other experienced people will comment. Regards, Randy L.
