Message: [QUOTE="Badgadjit1, post: 1204748, member: 67273"] i have a yz 250 and had to go through the same thing..i have a hot rod crank in my bike, its great. I read in this thread someone told you to use heat to take it apart and put it together..this is correct. this is what i did. going off of my bike...one side of the crank is pressed in and the other side isn't so heat up the bearing so it expands and just knock it out witha brass hammer..since its no good. and its definetly cheaper to get a hot rod crank than reguild the crank. (i may be wrong but thats what i found when i did this) To get the bearings out, heat the case up around the bearing so the case expands and there isn't as much preasure on the bearing so it will come out easier. When your putting the crank back into the side that was pressed in, ( i called a shop to see what they do to get them back in, it didn't see right what they said but it worked, i didn't have a press so i didn't really have a option) They told me to heat the bearing and very easiily and uniformly tap the crank into place with a brass hammer. I would also definetly replace all your seals while your in there, why not, cheap insurance. and my cases where put together with liquid gasket for the two crank halves, and then with a gasket on the clutch side. Just make sure you follow the manual and don't end up with extra parts.. :laugh: Good Luck! [/QUOTE]
