    hey drif. the new bearing has a taper lock sleeve, no? remove the taper and see if the crank turns easier. maybe its loaded on the other side of the crank. :dunno

    when you put the new bearing in... you put the bearing in first, then punch a tapered sleeve into the inner race... right?

    in the pic below you see the inner race is loose on the crank... note there is no "germany" written on the inner race also...

    in the pic below you see the taper being punched into the bearing to fasten it to the crank.

    have you got the bearing in backwards? that'l make her tighter than an.... never mind. really tight!

    Lost me here, Colin. In the second pic, that is just a washer that slips on, comes with the bearing, no taper at all.

    I am not sure that there is a differecnce between forwards and backwards. I put the inner race on first, then the bearing, then the spacer(2nd pic). Some one at KTMTalk (or here) put the spacer, then the bearing, then the inner race.

    The other persons thought was, once you bury the inner race in there, there is no getting it out. If you put the inner race on last, there is a easier chance of removing it if you need to.

    Not sure which is correct. Maybe someone with an '03+ can look at their engine book.

    That's not the right bearing in that pic.

    That's it, #11.

    Drif10, how'd you end up getting that bearing out?

    Nope , thats the crank shaft, looking for the main output. Has the clutch on the end. Transmission , not crank

    Yep, thats it #11, but they just show the whole bearing, not the three components. Bummer

    I've never cracked open the case halves. Is there any way to wonk up the thrust by using a puller that pushes on the shaft rather than the case?

    ???[/QUOTE]

    No Way, the forces are only on the shaft, no force is on the clips back there.

    EDIT: You know what ... the more I think of it, maybe you do pull on those clips a bit. If the bearing was attached to the shaft, no pressure. But because it is attached to the case(via friction) there is some pressure to the circlips.

    HiYa GK. Cool. We meet up in Calexico (somewhere) early on the 18th and run south. Or you can catch us somewhere down below. Keep an eye on the BAR thread.

    Hijack off.

    So is the bearing out of spec, or the shaft bent? It was fine with the old ball bearing, so I can't think of what else may be the problem that is loading that mainshaft.
