tyguy71 Posted April 20, 2005 Report Share Posted April 20, 2005 I just rebuilt my motor on my banshee. I put a new bottom and top end. The crank is stock, and the pistons are .020 over wisecos. I'm certain that i assembled it properly, because i had a blaster that i rebuilt several times. The problem is it wont quit burning crankcase oil. I only have probably one tank of gas thru it. Do you think it just needs more time for the rings to seat? or is there a bigger problem? Could the machine shop have messed up the bore job?? It seems almost like its and intermitent thing, but im not sure. Any help would be appreciated Leave a message, or email at tyguy71@hotmail.com Quote Link to comment Share on other sites More sharing options...

ssanddemon Posted April 21, 2005 Report Share Posted April 21, 2005 The rings have nothing to do with trans oil usage, period. The only connection between the crankcase and the trans is the crank seal, it HAS to bad. Unless the case havles are leaking trans oil into the crankcase, seriously very remote.

The oil you put in the side case never sees the pistons unless you have a big problem. That oil is to lube and cool the clutch and gears.

Is it going to be possible for me to remove the seal without splitting the case?? Quote Link to comment Share on other sites More sharing options...

papa_smurf49319 Posted April 22, 2005 Report Share Posted April 22, 2005 like stated above your premix lubes your bottom end crank and rods, and the tranny is separate. Quote Link to comment Share on other sites More sharing options...

tyguy71 Posted April 22, 2005 Author Report Share Posted April 22, 2005 (edited) A hi-temp silicone I think i just got in a hurry and stuck the seal on the wrong direction Can anyone find me a pic of which way the seal should be?

I really, REALLY like Loctite 515 for engine cases. It stays gooey until it's put under pressure, then sets up fairly stiff, like plastic. It's especially designed to seal machined surfaces. The bit of sealer that squishes into the case when the halves are bolted together stays gooey but never dissolves in oil and won't come off to get into the gears; but it's a real plus on 4- strokes with an oil pump pickup. I have seen an awful lot of motors with silicone bits plugging up the pickup screen, lemme tell ya! The real beauty of this stuff is that it stays wet until the cases are tightened, no rush to get it done before it sets. The crank seal direction is easy. It has one side that is smooth and another that is raised with several notches. The notches face in. I have replaced the seal on the stator side on my bike without splitting cases, but it was a bitch. I ended up drilling two small holes opposite each other into the side of the seal toward the crank. I then ran a sheet metal scew into each hole and walked the seal out by pushing off the side face of the crank by turning the screws in. Putting in the new seal was easy, just smeared it with 515 and drove it in. The 515 set up and locked the seal into place while also filling any marks left from the old seal removal. It was a pain in the butt, but waaayy easier than splitting cases. Quote Link to comment Share on other sites More sharing options...
tyguy71 Posted April 23, 2005 Author Report Share Posted April 23, 2005 Alright, I had the seal in right the first time It's hard to believe i could be burnin that much oil just from it leakin thru the case, but i guess i will give that loctite shit a try and hope it solves my problem.
