excellent video. thanks. how do you make sure air has not been introduced into the system - you noted that is important?
I need the same thing. How many hours did your old one last? Mine only has about 150hrs and it’s shot.
This exhaust system only had about 320hrs on it when it failed
That's a different type of compression check.
Red RTV is good stuff
Very nicely Done! So nice to find the problem and it was a simple fix Thank you 😊
LOL, that must be the new high pressure mod😂

Thank you for putting together the explainer! What was the cause of the damage?
Never store them outside
Nice work! Very nicely done 😊🇺🇸🇺🇸🇺🇸🇺🇸
What about the compression washer that came with the 912 oil change kit I bought from LEAF? I didn't see that mentioned anywhere.
That’s because he has this drain valve on his. When you remove the drain plug on the bottom of the oil can, you logically replace the crush ring with a new one when re-assembling.
Hi, can you hand prime without presrure ? and purge the lines of air if you dont have access to a compressor etc, thank you.
Great 👍🏻👍🏻
Great
My Rotax powered aircraft was spitting oil today. Upon inspection, the oil filter was noticeably loose. Wondering if it was improperly installed or vibrated loose over time. Mechanic said the Rotax motor is the only airplane motor he knows of where the oil filter doesn’t lock into place. Dipstick reading in the middle pre- and post-flight.
Very nice Video, good explanation, very good part when you show the tools which are neccesary. Greeting Germany
Cool, wich material are the red short tubes?
I used a 1in heavy duty heat shrink with built it glue that seals. It’s not fire resistant but it keep the lines sealed and fuel from wicking into the firesleeve fiber
@@JM_Aeroservice looks great! Greetings from Welzheim airfield❤️
Not until TH-cam lets me monetize 😅
Any chance you’re planning a in-depth video on this one?
Very well done. Good editing. Thanks!!!
Thank you! 🙏🏼

All these things make aircraft 100% performance

That would be a value for the overload clutch break away not the friction torque resistance that we are testing for in the video. Both require locking the crank shaft as described in the video.
So 100 gram is 0.981 Newton
1.019 grams is 1 newton
mate greetings from Australia. just came across your channel. great information and very well explained. look forward to viewing more content. cheers
Awesome, thank you!🙏🏼
Great video! What causes that damage?
EMOTIONAL DAMAGE!!! 😂 GREAT TO HEAR SOME WARREN ZEVON!! WELL DONE.
Warren Zevon -- always a good call!
That’s not that bad
Did you tighten the screw that holds the thingabob to the dodywacky is what I always say to my mate when he fixes them 😅❤
How it should be done 💪🏼
Ouch
Flex pipe my friend
Is this part 1?
1. Did you actually rotated the prop. 50Xs?? 6:39. You mention putting 2.5 lt of oil, then running the engine, burp, then adding the additional remaining oil, correct? How long did you run the engine for? Great video!!!!
Excellent video, kudos to you my fine sir !
Excellent tutorial. Thanks.
You're welcome!
Thank you for your time with making this video.
My pleasure!
Very nice, thank you! If you did want to drain the oil cooler, what is the procedure to fill the system? 100 turns?
Your Rotax oil change videos are very helpful and greatly appreciated. Thank you!

If there is at least one spark plug removed from each cylinder, there are no blow-by gases available to increase crankcase pressure and push oil back from the dry sump (the bottom of the crankcase) into the return line. Maybe that's why the return line is directed against the ground, so oil can follow gravity. However, while it is clearly in the interest of safety to remove the spark plug so the engine won't be able to suddenly start, I wonder if there is a real technical reason for removing the spark plugs. You say you turn the prop about 100 times before you see oil coming out of the return lines. Why is that? If the spark plugs were fitted, it would only take a few rotations of the propeller to increase the crankcase air pressure enough (by manually created blow-by gases during engine compression). I know you just follow guidance provided by Rotax, but still I wonder if having the spark plugs fitted would impede the oil purge in some way. Any ideas?
If I put four of these babies on my car could I fly?
When balancing carbs would you recommend the carbmate or analog gauges ? Could you recommend where i can buy either ? Thank you
Excellent videos! Nice detailed description of the process
Will this procedure work with a high-flow in-line engine oil thermostat install?
Thanks a lot! Perfect step-by-step process description! Go ahead!!!!
very helpful indeed.
Excellent
Love to see a video pulling the gearbox and sending off for inspection.
I fill my oil filter with oil before installing. I think that’s the procedure now.
