Default Clutch shell wobble

How much clutch shell "wobble" is considered normal if any when turning the clutch hub, no plates installed. No real amount play can be felt when grabbing the shell and trying to move it just when turning the hub.

What year clutch? Never mind, I misread... Zero wobble as it's turning.

check clutch hub to trans shaft interface as a little anything can result in wobble. Look for any debris or dings

A clutch outer shell will wobble if you hold it still and spin the mainshaft.

Sorry it's a 1997 Electra glide. I tried to up load a video and it said it was too big. I will later try to make a shorter one.

My clutch is a 90-93 setup oem type.

The outer shell will rock back and forth slightly, enough to notice, if you hold it still and spin the mainshaft (of course the disks and friction plates must be removed).

I knew you'd changed yours but I'd forgotten.I agree the shell will rock a bit which is an exaggerated motion allowed by normal bearing play.

If you put pressure against the shell or pull with your fingers, they shouldn't wobble. But I can see a slight wobble if simply holding shell in one spot.

inner hub 2 connects to shaft, so if you go to spin the inner hub with clutch removed, and it not running tram to trans input shaft, then best guess is either trans shaft if bent, or start of inner hub spines have chipped off and why it no longer running true with trans input shaft,
[img]https://www.hdforums.com/forum/attachments/touring-models/539920d1501528163-damaged-clutch-hub-splines-secompensator030110__01.jpg[/img

Now on inner shaft, you have bearing 9, and depending on how tight the bearing still is, make have a little play in the bearing that you can pull pull the outer clutch hub 3 in and out to feel some of that play.
Note, could be bearing is loose in out hub channel channel, and beside some light play in bearing, may be feeling play of bearing in channel as well.

Now the real test, is to spin the inner hub via the rear tire, and with primary chain holding the outer hub in place, and check how bad the outer lip of the outer hub is oblong dancing in and out. Hence bearing inner race on inner hub, out race of bearing on out hub, and if bearing is either beyond trashed, or bearing is no long seated tram in outer hub for it, outer Hub is going to spin out of tram to inner hub shaft.

As for when you run into this out of tram spinning of the outer hub to inner hub shaft or just bearing loose in outer hub channel, with the bearing still good, it does not always mean that the outer basket needs to be replaced. Clip 8 holds the bearing in place in the outer hub channel, is not hard to clean up that bearing channel in the hub so it will seat tram again to bottom of channel, loctite the bearing in place seated all the way down and tram to bottom of channel, then shim between the top of bearing outer race to bottom of C clip, so clip is holding the bearing tight trammed in place to bottom of channel.

Simply, there is the wobble of the basket itself as the bearing will starts to wear or becomes loose in the outer hub (some bearings a looser then other when even brand new)

There is the wobble of the inner hub to shaft when trans input shaft is turning (broken spines, or bent input shaft),

And there is the wobble/out of round rotation of the outer hub to inner hub when the bearing is not tram to the two.

If you tell is which of the three you have in question and amount of slop (which sounds like your asking about the first), then could be bearing starting to go south, or could just be bearing is not longer tight in outer basket channel for it and what you are feeling over normal movement in bearing.
