Re: Engine upgrade

Can you use a 1b-90 prop on a continental 0-200

The Harer STC only allows the use of a C-85. You might be able to use it as a basis to get a field approval for an O-200, but field approvals are very rare these days. There are many on this forum who have installed an O-200. You might do a search and contact them for a copy of whatever paperwork they used.

Regarding which prop to use with an O-200, you can find that info on the FAA website, under Type Certificate Data Sheets.

Re: Engine upgrade

What if you de-rated it to the same as a C-90? Would that work?

Re: Engine upgrade

10% or less power increase is a field approval, above is STC only. Per change 19, This is the guideline that the FAA uses for what is allowable at the fsdo, stc and engineering approval. Tim

Re: Engine upgrade

Why not just do the 85 with the "stroker" STC (0-200 crank)? Then it's more than a C90, and totally legal and hassle free?

Re: Engine upgrade

My buddy wreck his c-150 with a 0-200 and will make me a killer deal $1,000 for the engine complete is that a good deal.

Re: Engine upgrade

That depends a lot on the engine, it's age, condition and what happened to it in the crash. It should be somewhere between a boat anchor and solid gold.
Not trying to be funny, you even have to be careful with engines with perfect papers and a fresh major. Check it out with a well trusted mechanic. Your life depends on it, even if the seller is your best friend.

Re: Engine upgrade

For a complete engine how could you go wrong?

Re: Engine upgrade

What Hank said....... if it's been prop struck, it could be worth scrap...I guess the barrels would be worth a little..but not much.... on the other hand if he backed over his plane with a tractor or something and didn't touch the engine, you might have a good deal..... sell it and get a stroker 85, then you're legal and no problems.

Re: Engine upgrade

Funny thing we call an "aerosol overhaul". I got a freshly majored A-65 with less than 6 hours on it.
Yada yada, lots of details that don't matter, but I had to open it up. NOTHING was overhauled. Nothing was usable. The valve seats hadn't even been ground. The cam shaft was no good, several cylinders were cracked. The engine was JUNK. The amazing thing was, he FLEW IT, several times! It smoked some and didn't produce full power, but it DID run, and was pretty smooth from what I was told.
If that piece of C**P could fly a Taylorcraft, I am REALLY impressed by Continental engineering and manufacturing. What I had was a core with fake paperwork and a REALLY nice paint job. If I had believed the logs with it, I probably would have used it, and no telling how long it would have kept running before it had a catastrophic failure.
Don't get me wrong, this engine could be a real jewel, or it could have been critically damaged in the crash. CHECK IT before you buy it. Engines make really lousy coffee tables. They just won't stand up on the kidney tank!

By the way, I ended up OK with the engine. I learned how to do a major on it. It's like new now, wrapped up and stored for when I need it. Only problem is the IA who taught me while we did it, DIED before he filled out any paperwork. I used to have a bad engine with papers (fake, but who would know) and now I have a fresh major engine with no paper!

Re: Engine upgrade

My first A&P/IA had the audacity to do the same thing. (Up and die before we were done.) So rude. He was an incredible person, not to mention an amazing technician. Lucky for me, most everything I did with him was able to be reviewed and approved by subsequent IA's.

Back on topic, you've got to check the engine carefully. Even a soft prop-strike requires a partial tear-down to be safe (and legal).

Re: Engine upgrade

The worst part was the loss of a good mechanic and better friend. I have since found a really great IA who I will be rebuilding the engine (again) and we will make it all legal. Based on what he has said it should be a good weekends work and the cost of a seal kit.
Well worth it. After all, moisture may have gotten in and for the cost of a set of seals I will know it is right.
Hank

Besides, how can an engineer pass up the opportunity to take something apart! You know, there is nothing more dangerous than an engineer with a tool!

Re: Engine upgrade

There is something more dangerous and that is someone with tools that isn't an engineer...

Says WHO? Dial it and run it under part 91!
