 Posted: Sat Apr 12, 2008 1:07 pm Post subject: ROTAX 912 Used Engines |
 |
|
Good afternoon,
Have been watching eBay and Barnstormers listings for used Rotax 912
(100hp uncertified) engines. Several have been described as having
suffered from prop strikes, others not damaged due to other crash damage
or whatever. Would any of you with experience with this engine offer
any advice on having one of these rebuilt (lower engine price + rebuild
cost) being anymore cost effective over a new engine? This is a new
area for me and I'd really appreciate your counsuld. If there some
specific sites for information about rebuilding vs new could some of you
tell me the locations or URLs? Thanks. John Reinking,
Woodinville, WA PS. I've learned my lesson per speculation and
amateur-engineering. Leave that to the experts and spent my time
trying to learn more about our joining the birds 'up there'. Thanks
again.

John, my experience goes something like this:
1) Dont assume anything about the condition of these motors (they could be
great - they could be real bad, and everything in between)
2) If an engine has been involved in an accident and you do not PERSONALLY
know that the prop never struck anything, then you need to get a crank and
prop shaft runout test. Quite simple but if you aren't going to do this
yourself - any Rotax mechanic can do it for about $100 This simply checks
the runout of both the prop shaft and crankshaft (must remove gearbox) to
see if they were bent (using a typical runout dial indicator). The specs
are published in the Rotax manual. See if the seller will let you have this
done before purchase.
3) If your engine PASSES both runout checks, it may be worth it to purchase
it and then send it to either Lockwood or Leading Edge Airfoils (repair
depot) for final checkout (call them first for price) of the engine.
If it FAILS this runout test - there is a good chance you should walk away -
unless you can do Rotax engine repairs yourself... otherwise you may find
that bottom end repairs (crank) will cost at least $5K... and probably
more... so with current engine prices you have to do the analysis of cost of
repair vs new....also, if the engine was overheated, the heads often warp
and these are really expensive to replace....
4) These damaged engines are perfect to keep as part spares (and are often
snatched up by repair centers) as their 'good' parts are well worth many $$$
for the used part repair market. This makes a lot of sense (and money) for
that purpose.
5) without this or similar analysis, you are simply taking a roll of the
dice.... my last suggestion is to call a repair center (Lockwood, etc) and
discuss this with them... they have no magic ball BUT can give you prices
for teardown/analysis/testing...
It is tempting to pick up an engine that cost $20K for a mere $5K .... but
do your homework first!
Been there, done that, sort of!
Jon

The main problem in buying a damaged engine and rebuilding is if you don't know how much damage is there. So, the only safe thing to do is get a cost for a worst possible case rebuild.

Hi John,
I've been watching that one on eBay from Florida also. I asked the seller if there was a prop strike involved. He admitted to me he honestly didn't know. He bought the engine from the guy that trashed his plane. Here is what he'd written back to me:
Sir, I really don't know. I bought this engine and panel 2-years ago 2ND hand with the idea of buying a CH 701 kit. I was not present during the accident, nor was the pilot present when I bought the engine. I was told He was landing in a pasture when the landing gear snagged a power line. Then the plane was snatched backwards and at this point the pilot (former fighter pilot) killed the engine. Then the plane nosed over and hung for a second or two then dropped down about 10 feet and hung again. Then the wire broke and the plane fell down 10 more feet into a plowed firebreak. The pilot unstrapped his harness and stepped out completely unharmed. So it hit the ground with the engine off. That said; when I picked up the engine I saw one broken prop blade(3-blade composite). So I don?t know if hit the wire and broke or if it broke upon hitting the ground. This engine has the slipper clutch in the gearbox that is supposed to cushion the crankshaft from prop strike. I hope this is helpful.
With that being said, I would probably NOT attempt to buy this particular engine because he knows little or nothing about it. I'm afraid by the time you purchase it, ship it to you, and possibly have to have it rebuilt, you will be spending 3/4 the cost of a new one. I personally am building the 110 HP Corvair. I'm expecting to come in way less than 1/2 the price of a new Rotax or Jabiru too. If you don't want to build it yourself, there are people that do that sort of thing. If your interested, contact me off the forum and I will give you several reputable names that do. Hope I've helped you out some. Oh, another word of caution, I've heard (but not seen for myself) Rotax has a recall going on with their redrives. I don't know what is involved in it. You would have to research this more to find out.
Regards,
Larry Hursh

Boy, thanks for the info. I figured this was a not too prudent idea
but wanted to get some more experienced input. Am thinking as a result
that keeping my ear to the ground here at S43 and posting at some of the
local EAA Chapters that there'll be a better opportunity than eBay.
Wanted to go the corvair 100hp route but since the wife and I aren't
very skinny, looking at the Rotax (sorry, Jab 3300 way out of my current
position) would be a good weight alternative not to mention it's regard
in the community.

I'm confused, doesn't a new Rotax cost as much or more than a Jabiru 3300?

Hey Craig. I took this information straight off of the Jabiru USA website:
Jabiru Engine Sale!
3300 Regular price is $18,400 Sale Price $16,400
2200 Regular Price is $13,900 Sale Price $12,900
Jabiru Australia has reduced the price of the engines to its dealers for a one time sale that ends April 15th! This is the first sale for Jabiru in 7 years! Engine order payment will be due by April 15th and engine deliveries will be at the end of June. Call for all the details!
