I’ve got it apart now does it look like it moved?
There is no way to press out the bearing on the outside race. If you press out using the inside race would that put too much stress on the bearing?
Also the last picture there is a chip on the end of one of the splines. The chipped piece was in the splines of the stub shaft so nothing fell in the engine. Should I be concerned about this chip?
It concerns me that it appears that splines on the end of the crankshaft are damaged and one is missing. I wonder if someone tried to force it on when the splines were misaligned. The only way to fix that would be to replace the crankshaft, although I doubt that is necessary. There appears as though there are still lots of splines left for strength but you may have even more stub shaft/ clutch rattle then most Winders.

Yeah, that's not good. I didn't look at the pics close just read his post. At this point like SSbob said only way to "fix" is going to cost some $I think that spline shaft is actually the end of his crank.
Will it be fine as is....probably.......is it concerning......definitely

I believe the one that you think is missing,is actually made like that so that the stub shaft will be indexed in the correct position. I just had mine apart and it was the same ...minus the chipped spline.It concerns me that it appears that splines on the end of the crankshaft are damaged and one is missing.

Zooming into the pic I see what your saying. Looks like the very end of one spline is chipped off and the one beside it has a gouge. It definitely got forced on there or something at some point in it's lifeI believe the one that you think is missing,is actually made like that so that the stub shaft will be indexed in the correct position. I just had mine apart and it was the same ...minus the chipped spline.

Pack some rags in the bearing and use a dremel tool with a small stone to remove the jagged edge on that broken spline, it will be fine. Just clean out the housing throughly before reassembling.
Make sure the stub goes on easily. That spline is heat treated and if you don’t debur it, more can crack off. Don’t be shy there’s plenty of splines left to hold the load. You don’t want the crack to grow into the shaft, kinda like a glass crack.
It doesn’t appear your stub has moved more than 1mm, but press it all to together with loctight and see what you come up with.

Oh that's good to know...makes the situation far less serious. Just clean it up a bit and should be good to go.

I think he's right.
If you look close at mine, it has a missing spline.
You'll just have to clean up the end a touch

Yes the shaft is indexed because the crankshaft position sensor reads off this tooth wheel on the older model genesis motors. I assume they just kept the indexed crank and shaft to save on re-tooling?

The chip I was referring to was on the spline to the left of the Index splines. I'm not going to lie when I first saw the index splines I shat my pants a little but then after looking at it it was too clean to be broken. I cleaned up the end of the chipped spline, pressed off the stub shaft and bearing then reinstalled with green loctite. I also used some yamabond on the stub assembly where it bolts to the crankase. Once reassembled gained a little over 1mm outward on the stub shaft. I torqued down primary (108 ft.pound backed off then final torque to 43 fp) I rechecked the offset and was tight on the guage. I reinstalled the bearing circlip and had to add one shim for the offset to be correct to the hurricane tool. I also had to machine 3mm off the plug for the belt deflection to be close. Thanks for all your input guys, just waiting for snow to test now.

Nevermind . I kept looking and found it.
Where is the stub shaft bearing found when looking for it on the parts fiche?
Thanks..

soooo - on the stub itself - those teeth with the notch are useless and could be removed?? and lathe cut smaller,, rotating weight on crank is big...

No not useless on my 2015 viper, I need them for crankshaft position. Not sure what year they changed?
