Super Jet Need help! My superjet blown 2 crank seals in 1 month

[SuperCarlus]

I had a 701 and the outer crank seal near the driveline coupler was poped... ok maybe a backfire in the garage can do that. I removed the motor to change it. At the same time, I changed the cylinders and pistons to upgrade to 62T BB771 cylinders and dual 44. Today, I was triing ajusting those carbs and another bang! It blown down AGAIN the same brand new crank seal! Is this powerplant thirsty and just wanted to drink some fresh water by the crank or what??

I feel sooo alone and just don't know.... what's your opinions? Can a superjet motor burp crankseals like that?? Ever seen?? I have to fix it before re-doing all the maintenance, because it's a lot af job



oh, the stator is at 0 degre of advance, msd cdi, msd coil.

Oh Lord, take my Superjet with you, bless him and go faaaaaaarrrr!

i have been through this several times. the oem seals have a more square ridge on the m than the wsm. however this may or moay not be the issue, the other issue is the rear bearing alignment with the pin in the case. it will rotate just a pinch to cause the cases to not seat fully

hummm the case was fully seated and sealed. The seal pop out from the case! damn

Tit's out on the rear seals?

 

[SuperCarlus]

the tits of the inner seal was rear side and the lip/spring of the outer seal was rear side too... was it ok?

Go see this thread:

and look at pic #3. I'm betting you put your seals in wrong both times. The tits are supposed to be on the outside of the outside seal.
