Infamous039 Posted September 16, 2013 Report Share Posted September 16, 2013 I have never had this issue personally, but I am guessing that the seal may be warped/ defected or something from the heat of the motor. I would say if you have to split the cases then replace all your seals with some good brand seals. Quote Link to comment Share on other sites More sharing options...
dave5.0 Posted September 16, 2013 Report Share Posted September 16, 2013 Make sure you don't have a case vent clogged with crap. Could pressurize the cases when it heats up and blow out the seal. Quote Link to comment Share on other sites More sharing options...
woofy Posted September 16, 2013 Author Report Share Posted September 16, 2013 Thanks for your input!! Guess I got something to do this winter I didnt wanna split cases yet. I told myself Next time it would get a 4mill crank. Isnt in my budget yet.Thanks again Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted September 16, 2013 Report Share Posted September 16, 2013 That's the one seal that you do not have to split the cases to change, that's why it pushes out with pressure build up. Again check the vent below the rear motor mount and hose coming from it. Quote Link to comment Share on other sites More sharing options...

Coupelx Posted September 16, 2013 Report Share Posted September 16, 2013 Use something other than that orange shit when you reinstall it too. Quote Link to comment Share on other sites More sharing options...

salmon_slayer06 Posted September 16, 2013 Report Share Posted September 16, 2013 (edited) happened to me couple weeks ago. I ended up putting it back in without any sealant. Yup I know, it sucks. Try having that happen on a freshly built motor, fresh paint all nice and clean and getting oil and sand all over everything.

Strm Trpr Posted September 16, 2013 Report Share Posted September 16, 2013 So, crankcase pressure is leaking into the transmission and over pressurizing the trans and consequentally blowing the front sprocket seal out? Quote Link to comment Share on other sites More sharing options...
Tedder Posted September 16, 2013 Report Share Posted September 16, 2013 Clean the cases with carb or brake cleaner and make sure their good and dry then put it in a new seal without any sealer. I agree that the vents need to be checked. Quote Link to comment Share on other sites More sharing options...
salmon_slayer06 Posted September 16, 2013 Report Share Posted September 16, 2013 no. From what I get out of it..... if you are heating up the trans oil.... from riding long enough to warm it up... the pressure inside the case goes up. It just does... the vent on top of the trans case near the swingarm bolt should let this pressure build up escape or "breathe". If its clogged by dirt or whatever it will find a way to escape. Too much oil could cause this... check level after it has been ridden for long enough to warm up but let it sit for a few minutes to get an accurate reading.

Ahhh, that's some serious heat build-up then. Quote Link to comment Share on other sites More sharing options...
Coupelx Posted September 17, 2013 Report Share Posted September 17, 2013 No but stuff expands when hot. It gets frothy and what not. It happens on the drive axles on trucks. Vent gets plugged with dirt and pushes oil out the seals. Quote Link to comment Share on other sites More sharing options...
