Diesel06 Posted August 25, 2012 Report Share Posted August 25, 2012 so i am very new to the forum and to the in depth ins and outs of the banshee ... problem ... just bought an 01 banshee was told by previous owner who only had it for a short time that it had been rebuild not long before he bought it ... got it to my shop warmed it up and took it for a spin " i drive everything like i stole it " get back into the garage oil blowing out of the crankcase breather ... bad crank seal install on the rebuild . it happens ... tore it down and found it had some play in the crank before splitting the case ... not happy ... split the case and seen it has a hot rod crank with pro x pistons with two very blown cank seals ... it also appears that it was completely missing the o ring on the stater side and the bearing and cases have minimal wear from spinning bearing ... my major question for some banshee wisdom is will it be ok to put an o ring on and that will be enough to keep it from spinning in the case and cure the crank up and down play that wiped out the seals or is it 100% a must to have the crank and cases taken to a machine shop and have them checked out ???

Diesel06 Posted August 25, 2012 Author Report Share Posted August 25, 2012 its almost no damage nothing i would be afraid to put an o ring on ... i am just not very familiar with the way that these engines use o rings on main bearings and if they will take up the play that caused the crank seals to fail and that there are hopefully no other problems going on in there to cause them to go Quote Link to comment Share on other sites More sharing options...
joey83 Posted August 25, 2012 Report Share Posted August 25, 2012 I don't know what o-rings you're talking about on the crank bearings. (no expert here) but I just rebuilt mine top and bottom and its not ringing a bell.. If it has slop check it and compare it with oem tolerances. Clymer book has all that. Its posted in here somewhere. Quote Link to comment Share on other sites More sharing options...
Bad one ton Posted August 25, 2012 Report Share Posted August 25, 2012 On aftermarket cranks there are o-rings that run down the center of the bearings. They keep tension from the case to the crank bearings. My wiesco crank has them as well. TON! Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
ticktock Posted August 25, 2012 Report Share Posted August 25, 2012 As B1T said aftermarket cranks use Orings on the crank bearings for keepers that the stock ones have. I believe in a conversation once I was told that stock crank bearings were discontinued so even rebuilt stock cranks will have Orings. Just order some new ones put it back together, check the squish and ride it. Adam Quote Link to comment Share on other sites More sharing options...
