wayne_smith97 Posted April 1, 2016 Report Share Posted April 1, 2016 I think I remember the builder of that motor. If it is who I think it is, contact them before putting them on blast. That builder has been good to me and a lot of others. Quote Link to comment Share on other sites More sharing options...
tdod101 Posted April 1, 2016 Author Report Share Posted April 1, 2016 Is it s used crank, excessive crank wobble will cause that seal to wear quick . Do you own any runout guages Apparently it was checked for true. So.. Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted April 1, 2016 Report Share Posted April 1, 2016 I wouldn't be worried about that groove. I don't think that's the issue Quote Link to comment Share on other sites More sharing options...

sheerider11 Posted April 1, 2016 Report Share Posted April 1, 2016 It's pretty deep The seal doesn't sit in that groove. If you look at your first pic, there space between the groove and seal.

Shifty722 Posted April 1, 2016 Report Share Posted April 1, 2016 In the past, I have always put a light coat of seal grease on my crank seals, is that a no no on Banshees or is it an ongoing argument? Quote Link to comment Share on other sites More sharing options...

sheerider11 Posted April 1, 2016 Report Share Posted April 1, 2016 Hmm, you're right. What you thinking?Someone smarter then me mentioned the seal used may not be that great of a seal. Maybe try a better brand seal and check it. And like mentioned above, fill the 2 lips with some kind of grease. I've seen many come from the factory this way. I use assembly lube on literally everything. Sent from my SAMSUNG-SM-G890A using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...

The grease heats expands and lifts seal. Attracts dirt to area. Needed because it's a dry fit. Doesn't matter. Always grease rotating parts. Those are the ones that stick out in my head.

Shifty722 Posted April 1, 2016 Report Share Posted April 1, 2016 (edited) sheerider11 Yeah I figured it would be a source of disagreement between builders. It is a less is more kind of situation, no globs of grease, just wet the seal surface. Edited April 1, 2016 by Shifty722 Quote Link to comment Share on other sites More sharing options...
tdod101 Posted April 1, 2016 Author Report Share Posted April 1, 2016 Faulty seal so be it can happen 100%.. but stating that it was previously leaked down tested and having a seal randomly leak now between the last time it was leaked tested and hasnt even ran yet... makes it somewhat unlikely that it was previously tested IMO.... shit can happen.. but I cant really even see that seal getting damaged or hit in shipping esp if the stator and flywheel and cover was installed when being shipped.... maybe I got spoiled with wildcard (aka spent a lot of money with them over the years lol) but they always cleaned my parts spotless inside and out before doing anything. It has one ride on it. Quote Link to comment Share on other sites More sharing options...
