nasty01banshee Posted April 26, 2004 Report Share Posted April 26, 2004 i just put in my new stroker crank and the bearings did not have pins like my old wiseco crank, anyone know why ???? Quote Link to comment Share on other sites More sharing options...
Alcoholic Posted April 26, 2004 Report Share Posted April 26, 2004 The bearings with the pins in them are about twice the price of the bearings Wiseco use on the cranks. Trying to save money I guess. I have seen no problems with the bearings they use. Quote Link to comment Share on other sites More sharing options...
MRMOONEY Posted April 26, 2004 Report Share Posted April 26, 2004 it has orings instead, they keep it from moving like the pins did, i am not exactly sure why but mine is the same way. prob cheaper to make or something Quote Link to comment Share on other sites More sharing options...

boonman Posted April 26, 2004 Report Share Posted April 26, 2004 The pins keep the bearings from spinning in the bores of the case. PIns are the ultimate protection. Rotax used O-rings for years. You know what, they switched to pns recently. Using o-rings to stop the bearing from spinning the outer race is not a very solid thing. They still spin. if the bearing spins, and they do, sometimes they wipe out the bore, ad you're screwed. Time for new cases. Quote Link to comment Share on other sites More sharing options...
