Is the S&S inner race the only one that is special with the mentioned in the other post by lookout that has an inner taper for more press to lock it up tighter? Is the Baker just a single row ball bearing? What did your's do when it went?

just a note, the clutch hub tightens against the inner race. When using a ball bear the clutch is side loading the bearing at 80lbs.

Is that why the inner race tends to walk inboard?

I personally do not think or see how the clutch hub can press on Baker's replacement ball bearing inner race. It is a slip fit on the input shaft and nothing on the inner transmission side for it to go against.

Your bearing failed due to sorry material that is no longer hardened thru. It was overloaded due to it's weak tensile, stretched and walked back. Just my opinion.

Don't use this method on the 07 and later bikes it will not work the same as the 5 peed bikes. The gears on the shafts will prevent the movement of the mainshaft.

Thank you for the heads up! So, one needs to follow the "trick" in the Bert Baker DD6 Install Part 1 youtube video for a six speed transmission at point 9:40.

There is no trick for 06 and up Dyna's, or 07 and up baggers and softails. Basically anything that came from the factory with a 6 speed. The gears will not allow the shaft to move.

Yes, if you slide your clutch on the mainshaft without the inner case you will see the hub slides against the inner race. Look at your first picture of inner case. You can see the starter gear grind mark. That is common when race is to far in. The updated main shaft is stepped so the race can't move in.

I would also think, if it stopped where you think it does, torquing the clutch hub would just keep driving it in. However, I see that rub and have seen that before. Know the chain did not do that and I do not believe it's the sprocket either. I think Harley did that with some kind of matching fixture in production.
