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 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.

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!!!
@GravityKnightFlying Жыл бұрын
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.
@RustyShakleford111 ай бұрын
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

@oneninerniner3427 Жыл бұрын
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👍

Test your crank pressure as per Rotax manual
@GravityKnightFlying Жыл бұрын
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?
@GravityKnightFlying Жыл бұрын
@@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.
@frednorthup1657 Жыл бұрын
@@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.
