Thanks Todd. I don't wish for you to be always working on your plane, but man I do love the videos where you're in the workshop tinkering with your Dad 😊
Great job of recording and sharing a problem and solution, glad your neck is healing... Sure would be cool to get some birds eye views of the Wind River Range north of Pinedale. What a fantastic region including the Three Waters Mountain...Best wishes.
Congrats mate on having the neck squawk addressed. Trust all 'came out' well. Looking forward to seeing the ID trip! I so appreciate the flying and gearhead content.
I hoist the tail up until the fin almost touches the hangar ceiling, lowering the engine bay, whenever I have to work on it. There are for sure worse places to break down!
Glad you were able to fly to a place where repairs could be made. Good way to improvise a seal installer! On VW motors the rear seal is installed in a similar way, but a larger diameter "pusher". Can't wait for the movies to get posted. And by the way, the Skymonkeyyy's in Germany always said "If nothing happens it's not a real trip!"
I had the same problem with my edge built engine. It ended up have built up too much crank psi. Hal said it is common on the big cylinders in fact 915 has 2 return lines. I put another return line in and solved it.
There's nothing like recent maintenance to cause an engine to go into 'auto rough' mode at night, over water or in the mountains. All instruments show good, but I swear I hear something wrong!!
I love the shot of Devil's Head. Was it in the Flat Tops you landed? If you go by Yampa, just to the west is a couple of reservoirs and then a land bridge called Devil's Causeway. That would be a cool place to take a few shots. The bridge is at 11,800 and narrows to about 4 feet wide. There are several places to land within a 1/4 mile. The best would be to the south as the hike in from the north has a significant climb to the bridge.
Ill have to go look where that was in WY I landed. It was some BLM south east of Big Piney. Thanks for the heads up btw, sounds like an awesome spot!!!
@@GravityKnightFlying We are planning to hike in the area of Devil's Causeway near the end of August. Would you like some pictures and video of area's you could possibly land?
I had that thought while scratching my head trying to figure it out. I checked mine, rigged up a soft small hose and blew through them.. they were good…Did you figure out what plugged yours?
@@GravityKnightFlying Yes it was a small pc of grey gasket maker that logged itself into one of the lubrication ports , because one was still working and the other obstruction was not visible it took me quite some time to figure it out that was about 100 + hours ago and since then all is fine
Seal is either getting hot and drying out or freezing and drying out. Put a silicone coating on the outside of the new one it will help keep it supple and add a layer of redundancy to the seal
S**t's going to happen no matter how thorough or prepared we are. From my perspective, you're very lucky and/or blessed. Here's my question - why is the new seal leaking despite your efforts and mods to reduce crankcase pressure? Did the seal location on the crank look good? Thanks for another great video! So glad it all turned out well!!!
Hard to say, crank looked good. Might be a little bit of oil from the weep hole on the water pump (normal). I’ve seen some rotaxes that seem to weep a bit from the crank seal too, might be the nature of the blow by / crank case pressure oil return system. It seems to be a very minor amount of leakage.
You check the shaft & bore where the seal goes in for any nicks or imperfections? And smooth them with fine emery or scotch pad. I'm sure you probably did. We use Loc Tite green stud & bearing mount on a lot of transmission input seals like the GM aluminum pump ones that have the propensity to push them out.
I did inspect, crank looked good, I used some stuff rotax called for to seal it in (special silicone)… it didnt seem to have any sealant on it when it came out…. Maybe why it worked it’s way out…? Thanks for info
Yeah that's the rear end of the crank looked like to me, so if it wasn't true the rear main would more than likely have runout & be going out shortly. Most likely just a bad seal or didn't install right from day one, being it was partially pushed out. It'll be fine now I'm sure👍
G,day from Sydney Australia. That is an incredible sounding engine. Is it a Rotax 912 and what year of manufacture? * Super cool engine hoist rail and dang good lighting!!! 🌏🇭🇲
i think your right, I don’t have adsb, but some of our guys do and didnt pick him up. One tried the radio but we got no response. All good, we all had the same idea and just wanted to say hi
Hard to say if that spec is right being an edge engine, with 50% more power (going to make more crankcase pressure). Its gone 60 hrs since repair so I want to cautiously say its all good. Other thing was the old seal didnt appear to have any sealant on it, which is called for in the manual.
@GravityKnightFlying mine pushed out 2 rear seals and any other orfice it could. It has less than 100 hrs on their total rebuild on a 99 case. Replaced most oil lines to rule out obstruction. Check the crank pressure just to be sure. Why did they put 2 return lines on the 915?
@@frednorthup1657 wonder if that was to keep oil from pooling whether in a steep climb or decent? Assuming front and rear ports both in use on 915 case. They also changed the spot they measure oil temp, on the case now and not on the pump. Wonder if the breather line is larger on the 915 tank, I can’t remember now. They should all be larger… don’t want any back pressure in that system once it reaches the tank.
@@frednorthup1657 another thing i did while in there was clock the banjo so one of the openings lines up with the line/fitting, then opened up that hole in the banjo slightly to match. I also used some special new hose on the return that is actually .5 ID instead of .44. Fittings also match the larger diameter. Figured anything to improve flow back from the case is a positive.
@@GravityKnightFlying I did that also. Pressure would go up to 10 psi. Make a fitting to go in the crank lock screw and check it just for my knowledge. We ran another smaller return line to oil tank similar to the 915 from the other oil plug.Pressure is now around 4 psi. Then I found crack in case and trashed it.
Wish idiots that use this type of horrible sounds would stop doing so. It is so hard on the hearing. Play some music at very low levels of just use the engine sound. You guys get a "F" for audio on this one.
😂🤣 oh, your poor hearing! So sorry my free content with 45 seconds of music hurt your sensitive ears. Please go troll someone else, you are not welcome here.
Glad you got on top of it so quick, and what a great teaser for what's to come!
good push men, there is no secret, hard work and dedication, and you have both,so thumb's up.
I’m glad you got it fixed! I’m looking forward to seeing the Idaho trip footage!
Thanks Todd. I don't wish for you to be always working on your plane, but man I do love the videos where you're in the workshop tinkering with your Dad 😊
One man super-pilot , pit crew, engineer and overall Jedi !!!
Awesome! What an epic trip. I can’t wait for the rest.
thanks buddy, and thanks for the help when this issue happened!
can't wait for the trip videos...your stuff is just the best on the tube.
Engine problems suck, but you dealt with it and moved on. Says a lot. I look forward to your adventure video next. Cheers from Winnipeg.
Sweet love the content dude your amazing UA-camr keep it up man good luck..👍

Glad i made it way bigger!
Great stuff. Be careful out there
Thanks, Todd. An interesting story. 👍

I’ve hiked the causeway. Super cool. Can you really land there? That’d be fun. Lots of flats on top
Second half was much better. Thank you.
I had the same problem, rear seal would last about 7 hrs each time .. turns out one of the rear seal lubrication ports was blocked

@@GravityKnightFlying did you check if it is running true? if it is not, it may leak a little bit in when new and get worse as it wears the seal.
@@rodsilva80 it runs true yes

G,day from Sydney Australia.
That is an incredible sounding engine. Is it a Rotax 912 and what year of manufacture?
* Super cool engine hoist rail and dang good lighting!!!
🌏🇭🇲
It’s an Edge modified EP912STi (turbo, injected modified rotax 912) with my straight piped exhaust off the turbo. And thank you!!
So there is a scratch probably on the shaft or housing? Hopefully its not blow by the rings. Maybe a sized ring do a compression test.
Hook her to the rafters - I’ve done it !
If a motor leaked as soon as I got it, it would be going BACK where I got it, pronto.
I spent 26 years as a A&P at a Major Airline, I ALWAYS has stomach acid after a Major Repair, who wants to kill 300 people. Good Video.
Im betting that Notar 500 heli had his adsb turned off and wasn't on the radio...
i think your right, I don’t have adsb, but some of our guys do and didnt pick him up. One tried the radio but we got no response. All good, we all had the same idea and just wanted to say hi
@@GravityKnightFlying Yeah, unfortunately a well known (amongst the local pilots and fsdo) tour operator in the area.
Run it hard ! O Dear -
Test your crank pressure as per Rotax manual
Hard to say if that spec is right being an edge engine, with 50% more power (going to make more crankcase pressure). Its gone 60 hrs since repair so I want to cautiously say its all good. Other thing was the old seal didnt appear to have any sealant on it, which is called for in the manual.
