I know people will argue "what is your life worth" but $1200.00 for a new crank is outrageous! I think rotax uses this fact to their advantage (scare tactic). I'm pretty sure the original owner never replaced it at 300 hrs. It now has 475 hrs on it. Just want peoples opinions and what they have done. > > thanks, > > Tony There's a fair bit of field experience on this that can help gauge what to do. Generally, with the 582, the probability of failures with the crank start to increase significantly after about 300 hours. The 582 is suped up a bit more than the other air-cooled motors (503 and 447) and the crank is a weaker spot than on those. It also depends on how hard the engine is run. The 582 isn't quite as durable at high power settings as the 503 and especially the 447. So if it lives at 6000+ rpm all the time, for instance, I'd personally make crank replacement required at 300 hours. I've seen 582 cranks weld themselves together on the bottom end at as low as 40 or 50 hours, tho that's fairly rare as long as the engine isn't run too hard. I've seen another come out of the case at 150 hours with almost 10 times the runout limit on the PTO end (failure was imminent in that instance). My personal take: If I were running a 582: - if typical power settings were 6000 rpm + all the time, crank replacement at 300 hours would be required regardless of visible condition (this is an underpowered or borderline abusive situation, IMO). - 5400 to 6000, I'd start being more vigilant about keeping landing areas in reach around the 300 hour mark. - 5200 to 5400, I wouldn't worry too much about replacement at 300 hours. I'd let it go to 400 or so. But that's just my personal take based on what I've seen with the 582 over the years out in the field. YMMV.

    I noticed that the piston ring was stuck in its groove on one side of the piston (both pistons on the same side). I will measure the pistons and see if they are within tolerance. I noticed some scoring on the intake side (possibly ice???) I know the previous owner flew in the winter quite a bit. The cylinder walls look good. The piston connecting rod bearings I can use off of a 583? I see ebay they have rebuild kits for the UL582, any good?279.99 for gasket set, pistons, rings.

Can I just buy 583 connecting rod bearings or wrist pins if it needs them? Anything I should be looking for in particular that is a known problem area for these engines? There is no cheap place to buy 582 parts because there are no cheap 582 parts. Again just speaking personally, I wouldn't put anything other than the correct/OEM 582 parts inside a 582 especially anything having to do with the crank and pistons. The metallurgy, I'm told, of the sno-mo pistons is different than the stock Elco ones (these are harder and have a lower expansion rate to help prevent cold siezures). Steve Beatty has been rebuilding Rotax cranks for many years, but I have no personal oexperience with those (I've generally heard good things anecdotally). Like I said, the crank is the weak spot in the 582 especially the bottom end. For example, if you were to lay out 447, 503 and 582 cranks on a table side-by-side, you'd be hard pressed to see any big difference in size (except for the helical gears on the 582 crank that drive the RV). Yet the power output difference between the engines is pretty dramatic. The top end, RV shaft and other parts of the engine generally don't give trouble and last for a long time. There was a rumor for a while that Rotax was working on an updated crank for the 582 but that that was apparently dropped after a while. I'd imagine that was because of the general decline in 2-stroke sales for Rotax. They're probably putting the lion's share of their cash and R&D into other motors like the 912 series. Too bad because the 582 is a fantastic running engine with very good power/weight....

    According to builder legend it weighs somewhere around 15 lbs more than the 3 cyl. If so, then carefully built, it would be about 155-160. I overlooked the fact that the engine combo I suggested was for a tractor installation and the redrive may have a too high thrust line. Some major butchering of the upper tier of your MkIII may be necessary. With the G10 on my Kolb, since I made no airframe mods, I could pop it off and install any factory-ready engine like a 912 in short order.

    Bob and Rick N.=2C Kolb guys=2C In my opinion=2C I think the 160 lbs idea for the 1.3L GEO is more than o ptimistic.

Although some of these auto engine conversions aren't exactly cheap=2C many can be had fo r around $7-8=2C000. This price allows the possibilty of building a plane to a lot of people.

    Robert That sounds super. A few years ago a guy was putting a 4 cyl Geo (same engine?) on his Kolb and it weighed some where around 190-200 lbs. Again that's what I was told. Rotax has a advertised weight of 30-40 lbs less than my VW but when installed they mysteriously weigh about the same. Eggenfellner was showing a Honda car 1500cc engine conversion with their redrive on it at Sebring. They claim 117HP @ 6,600RPM peak (110 @ 5800) with a weight of 199Lbs. The conversion kit with your engine is $7000 (complete engine $12,000) but that was with the conversion engine laid down about 45 degrees. Might be less upright? I made a "major improvement" to the Kolb engine mount to lower the VW enough to get a good thrust line but mounting a Rotax now would be, lets say, different.

The cylinder walls look good. The piston connecting rod bearings I can use off of a 583? I see ebay they have rebuild kits for the UL582, any good?279.99 for gasket set, pistons, rings. Where's the best place to buy parts for these? Thanks, Tony The rings on the 2-strokes generally start to stick around the 100 hour mark and usually in the vicinity of the gap. But they stay free enough to allow the motor to run normally for a quite a while after that. But at the 150 hr teardown, it's normal to have at least some sticking of the rings (a piece of old ring is the best tool to clean out the groove, btw. I still have some in my 2-stroke toolset). Scoring on the pistons indicates mild siezures, probably cold siezure from poor throttle management (lots of idling followed by immediate hammering to wide open and holding it there). Personally, I probably wouldn't put scored pistons back in the engine and would practice good throttle technique on the new ones. Personally (again), I would never put anything into a 582 that came from an uknown source. It's far cheaper overall to get the OEM parts from a Rotax dealer - the engine is in a known state after that and you're not banging up the plane or worse in engine-out/engine-falter situations....

    Hi Gang: Rick Neilsen does not like Rotax, period. If you do not believe me ask him. He is a VW guy through and through. He wouldn't fly with a 912ULS if Rotax gave it to him, delivered and installed, with a little hug and a kiss to go with it. However, you would not have believed the reaction I got from Rick when he flew with me out of Goulding's mile high airstrip at Monument Valley last year, or a couple a years ago. Even though he is not a #1 fan of Rotax, he sure had a big grin on his mug when we took off and climbed steeply out of Gouding's. Not hard for me to tell when someone is surprised and a little impressed. I may be wrong, but it won't be the first time, or the last, I am sure of that. Being a flat land furriner, I was a little impressed with the little MKIII myself. ;-) Anxious to get ready and fly to Monument Valley this May. john hauck MKIII Titus, Alabama I'm not the #1 fan of Rotax but isn't that 4 cyl Suzuki kind of heavy?

    John Yes I was impressed with your airplane it flew better than I imagined at Monument Valley, thanks again for the ride. But Mike Welch summed it up well. Some people just can't afford the price of a 912 Rotax. My goal is to lower the cost of safe flying so more people can. If people only buy Rotax engines the price will sky rocket even more than it already has. If I sound anti Rotax it is only because Rotax has the market sown up with maybe the best engine money can buy for the big Kolb airplanes , they know it, and they are profiting as much as they can. That makes it even more important, even for those of you that do buy a Rotax engine, that there are alternatives. Your welcome. Hey John I don't seem have your E-Mail address down here in Florida.

    Rick/Gang: I understand completely, and was being somewhat facetious in some of my comments about you and 912 engines. If I had access to a 4 stroke alternative engine that would provide as good performance, service, and reliability as the 912 series engines, for a lot less money, I'd be the first in line to get one. You guys that are working on alternative engines need to get them operational and get some hours on them. Make some significant flights. Fly them to Oshkosh, Lakeland, and other flyins. Show folks you have something to compete with the performance and reliability of the 912 series engines, by getting out there and doing it. By getting out there and putting hours and miles on them, you encourage others to do the same. john hauck mkIII titus, alabama Yes I was impressed with your airplane it flew better than I imagined at Monument Valley, thanks again for the ride.
