Great job on the video Sir. I'm ever so thankfull for you taing the time to share your knowledge & experience with all of us. I am now 60 years of age & the first time having to deal with these 'cageless"neede beaings (it wasn't as much trouble getting them out, as i suppect it would be getting them re-installed).I'm sure you are a few years my senior & it is so good to be able to learn from you. My hat is off to you Sir, well done & once again, thank you for shareing your tips & tricks. I feel a lot more confidant in the eventual re-installation of these needles (thumbs)...

Ty for sharing your knowledge ! These are real videos on Rotac repair.

Thank you, your experience is very helpful!

Thanks for sharing this with the world, , very nice idea works good

greetings and thanks for sharing your videos. where can I get that tool and its description. Thank you so much.

Recently purchased a Rotax 618 so this video series has been very informative to me. Thanks. You never mentioned the inner seals on the crankshaft or the lower rod bearings. Were they replaced or serviced?

I replaced the mag side bearings with the ones as shown. Could find no problems with the other bearings, but the center bearings would require taking the shaft apart, which I could not do. I have noticed no loss of rotary valve oil, so I am going to figure the seals are OK. A good video of rod bearings going bad is at: kzread.info/dash/bejne/i5Ocua2DgdGdhcY.html Action starts at about 9:45 on the video.

@@Adventurepilot70 From what I've read the lower rod bearing is a common failure point in these engines. Later models and aftermarket rods have two oil slots on the rod to address the problem.

My engine has just a single slot. I do not use oil injection. I use regular pump gas 87 oct. If I followed all I have read, I would have replaced the crank 4 times already. I don't know if the industrial main bearings I have installed will be better or worse, and I do not say anyone should do this. This video shows what I did. My rod bearings are free of play, are smooth in motion now, but dirt or damage from other places in the engine could quickly take them out. ( Like the fellow at 115 hours.) I am not in the engine business, and do not service engines other than my own, so I really don't know much about what happens to others. Many of my fixes do not workout.

do u sell this tool for a 800 ho rotax 2 stroke from a 2003 ski doo mxz

I don’t own a Rotax engine. I have been flying with a simonini.I’m looking towards purchasing a 582 for a powered parachute. I would love to purchase one of your tools, maybe put where in the description.

I saw a Simonini on a gyroplane at Carroll county airport about 2 years ago. Looked impressive. Where are they made? Thanks for your reply.

Thanks for the info: 1st. I have copied the info down and there are a lot of weird Bored people on the Internet. I don’t want to put you in a bad position putting your information out there unless you’re comfortable with it. Secondly, I purchased a video called deep inside your Rotax which taught me a lot I understand that it’s several years old and I appreciate the time you’re taking and everyone of these episodes to break down the engine and how it works. I understand it’s a lot of time effort and energy, along with editing. Outside of that the Simonini, Best I know is made in Italy, with a United States distributor. My engine is a mini2 which is quite a popular 202cc engine. I forget the horsepower that they specify. I think it’s around 18. They make a mini 3 and another engine which was of interest to me however I’ve only seen one video on KZread with the mini3. The other engine off the top of my head I can’t remember what it’s called buy them but I think it’s around 40 to 60 hp. Another engine I was interested in was the Kawasaki 440 which appears popular like a Rotax 503 but there really is not that much out there on that one as well.

The Simonini engine that I saw on the gyrocopter looked like it could be a replacement for a Rotax 582. It was water cooled and looked even bigger than a 582. On the outside anyway, it looked very well made. I will try to do some research on the Simonini to see if I can learn something. Anyone that watches my videos learns real fast that I don't waste much time on them, or editing them. I just record something I am doing anyway. The ones of the Chinook or Titan flying consists of a camera on the wingtip, and the whole flight is recorded. I now have learned how to cut sections out to edit for time. Thanks for your comments!

we're sending you 20 bucks for one. What about the snap ring tool? how do we change crank bearings? I just got a new set of cageless needle bearings from skidoo, they come in a cylindrical plastic clip the tool can be pushed thru

You might be correct. Main thing is to be sure bearing is full, and you cannot add any more. Needles are available at bearing shops, and are cheap, but they may need to order them, and they may make you buy a lot of them.
