0200 in a L16A

MikeB · Post by **MikeB** » Tue Jan 16, 2007 15:18

Don't remember if I asked this question before, but what's involved with installing a 0200 in a Champ (or in my case a L16A)? My basket case L16 came without a engine and I'm just thinking ahead. I realize there's a STC involved, but does the fact that it's a 7BCM and not a 7AC make a difference? I do have the big tail, no bounce gear and plan on installing wing tanks. Does the 0200 physically fit in the same cowling? I know some modification of the mount in necessary. I would probably not install an electrical system, etc. Also, know that the yearly spar inspection is required, etc.

Plan B would be to install a 85 horse (my preference) but have not had a lot of luck locating anything decent, even a good rebuildable core. A65 parts I have, but not much good here. The reason for looking at the 0200 is that I have a friend who was building a Tailwind and has a 0200 with logs and as the project has fallen by the wayside, I think the engine can be bought for a reasonable price. On the other hand, I'd like to avoid unforseen problems.

Appreciate any insight.

Mike, yes with the STC. You have to extend the cowl unless you convert the mounts, which Bill Pancake knows how to do. Annual spar inspections with anything over 90 HP

Mike,

If you buy the 0200 STC from Buzz, included in the STC, are specs/instructions for fabricating a new engine mount. It is constructed of heavier tubing and about an inch longer, give or take. The STC states that you can make your engine mount according to the drawings and specifications or you can purchase a stock mount for a C90 (I think it was a C90) or larger. You should also note that if you elect to build a mount according to Buzz specs, the tubing for the engine mounting bolt is sized for a 7/16 bolt. The bolt size for the 0200 lord mount is 3/8. So you will need to deviate from Buzz specs just a little to compensate for the difference in mounting bolt size.

Thanks for the info guys. As I said, my preference would be to come up with a rebuildable C85-8 or-12 for decent price. I have some issues to address with the airframe so I've got time to look around. However, I've had this 0200 on my mind for a backup just in case.

You might also consider converting an O-200 to a C-90, the only significant differences being camshaft and carb (different main jet).
Advantages: Can use a 72" dia. prop and no annual spar inspections.
The 7/16" holes in the standard mount can be bushed for 3/8" bolts.
The lower cowl has to be modified for increased cooling air flow - probably for an O-200, also.
Did this for my 7CCM which I acquired w/o engine (the O-200 I bought needed an overhaul anyway) and it worked out very well.

How do you come up with the information/paperwork, etc. for the conversion? Sounds interesting if I can't come up with a 85 horse which is "Plan A".

Believe that Dons Dream Machines has an STC for this? Nathan has done something like this, and hope he chimes in on the thread.

I believe you're right Joe. Don take's an 0-200 Crankcase and uses the steel of a C-75, 85, 90 [-8 or -12.]

STC #SE02172AT

So now you only have to come up with a mount that works. Might have to special make your own with the 7/16 holes, shouldn't be that hard.

MIKE,
Dons Dream Machines offers TWO STC's to essentially convert the C-85-12F to a pretty much a complete O-200. thats internals and externals. I just did it for my L3. The cost was $550 for both STC's. You have to use the C-85 data Plate plus an additional data plate that DON sends to you.
Those are Numbers:
STC: SE02172AT
STC: SE02004AT
Only requires a simple 337 for that conversion.
His name is DON SWORDS and his business is Dons Dream Machines phone number in Georgia is 7704128430 or "donsdream1@aol.com"

On the motor mount, there is a guy in TN that sells special Aluminum Spacers that converts the O-200 engine case motor mount back to the A65/C85 style motor mount. This will keep your motor mount short and retain the original motor mount diameters. I know several TAYLORCRAFT guyz that are using this approch to retain the original motor mounts and cowlings with the big engine upgrade. HOWEVER< His motor mount spacers are NOT STC'd so you would have to work with your FAA to get a one-time field approval, which I have found is no big deal. He sells those spacers for $100 and they are on EBAY. This guy is a pal of mine and his name is ED ATHEY; email, "eathey@hotmail.com"
