jbmason Posted March 30, 2012 Report Posted March 30, 2012 I was doing a little trail riding yesterday and after I. Climbed a hill and stopped tranny fluid started pouring out towed it back home and noticed behind the sprocket the seal has poped out of the case has anyone ever had this happened??? Quote
TIM LUTZ Posted March 30, 2012 Report Posted March 30, 2012 New one to me. Get a new seal, coat the outside with Yamahbond and tap er in with a large socket. Also check your case vent hose. It may be pluged. Quote
jbmason Posted March 31, 2012 Author Report Posted March 31, 2012 thanks.....has Anyone else run into this? Quote
Sandfrk33 Posted March 31, 2012 Report Posted March 31, 2012 Had one leak before, but never come out. At least you can replace it without splitting the cases. As already stated, use a little yamabond and push a new one in Quote
BigRed350x Posted March 31, 2012 Report Posted March 31, 2012 Sounds like a case venting issue or you're pushing pressure into the transmission area from a bad crank seal or bad case seal. I would NOT just pop a new seal in there. Do the job right and split the cases and check all your seals. Don't hack-job the shit do it right. Quote
Larry's Shee Posted March 31, 2012 Report Posted March 31, 2012 Doing a leakdown test first is hella easier, split cases, still gotta do it when done . The Blasturd blew that seal out after half hour of hot laps on mini flat track, between slightly overfull tranny and plugged vent tube it popped right out. Quote
jbmason Posted March 31, 2012 Author Report Posted March 31, 2012 Wouldn't it run bad if a crank seal was leaking enough to blow the seal out? Still haven't tore it all apart yet about lost the tip of my middle finger from the sprocket nut long story..... Letting it heal and got a few things to do first then I'm getn back to it Quote
TIM LUTZ Posted April 2, 2012 Report Posted April 2, 2012 (edited) Sounds like a case venting issue or you're pushing pressure into the transmission area from a bad crank seal or bad case seal. I would NOT just pop a new seal in there. Do the job right and split the cases and check all your seals. Don't hack-job the shit do it right. Oh hell no. Try a new seal with some Yamabond and see if it holds. Check your vent line. We want to ride this weekend not pull a motor and split the cases!!! Edited April 2, 2012 by TIM LUTZ Quote
Larry's Shee Posted April 2, 2012 Report Posted April 2, 2012 Sudden catastrofic failure might. I wouldn't split the cases for that seal until I blew it out the third time Clean case where seal goes with brake clean, pack and lube seal with grease, 3 bond on seal, wrap of masking tape on shaft to protect seal from rough shaft.

jbmason Posted April 7, 2012 Author Report Posted April 7, 2012 Thanks everyone..... got the new seal yesterday cleaned it up put some grease on it then put atf-rtv silicon (all I had) on it checked my vents and found it was clogged... it had to be clogged for a while cuz that stuff was in there just don't know why it took this long for that seal to pop out.. thanks again I'm goin ridin 8) Quote
Larry's Shee Posted April 8, 2012 Report Posted April 8, 2012 Around here there is a little mud dauber wasp that just loves holes that size, ground plug hole on outlet boxes. Blaster blew that seal after 1/2 hour of small roundy round track Quote
camatv Posted April 8, 2012 Report Posted April 8, 2012 push it back in and ride it. stop using atf crap Quote
