Clutch hub

Anyone have a clutch hub for sale I can't seem to find one without buying the whole assembly

I might have one as I just replaced my clutch with a Bandit. I'll check my spare parts this evening. What's wrong with yours?

My clutch has been slipping and I just put a new clutch in so I'm hoping if I replace the hub it will fix my problem

What do the steels look like? Those guys are toothed in there. You have 4 popping out of the grooves. Different plates? The others didn't ride over the teeth, but some look like they are about to? Looks like some rode over the others? Wrong steels?

One of the old ones.
I’m interested in how the distal end of the inner hub (#20) would be scored like that. Strange. I think it could indicate a misalignment allowing the clutch pack to transfer more force to the outside of the hub instead of evenly across it.
Did you have any metal shavings in the primary case oil?
I’d also look at the bearing in the bearing carrier (30), as well as the bearing carrier itself. They are made of cast aluminum and are known to fracture. Also while it’s apart, check the transmission input shaft. Just grab it and crank it around everywhichway. It shouldn’t have any play at all.
I had that kind of scoring on the outer hub (28) but the grooves were uniform. It resulted in the clutch sticking Because all the clutch pack plates open up open a vertical plane when you pull the clutch lever. The ‘ears’ on the friction plates would fall in the grooves and because it was pulling weight, they wouldn’t release if you pulled the clutch lever. If you started to move ahead, it would drag your ass out into traffic.
But the physics are different for the outer hub and inner splines.

Think of two dimensions of X and Y. X is spin fore and aft, Y is expand, and collapse. Those are the two movements.

This is how X uniformly hammers the indents via the pack of locked plates. Lift/accel/lift/accel... all that banging back and forth direction(s).

Operation wise, would you agree vertical is X for spin with plates at the upright position? Would not sticking be more like a problem the operation would come across as a variable, not how it works? This would be Y for a horizontal expansion of the plates now being two moving parts when clutch pulled.

The ‘ears’ on the friction plates would fall in the grooves and because it was pulling weight, they wouldn’t release if you pulled the clutch lever. If you started to move ahead, it would drag your ass out into traffic.
That brings us back to X times Y = Cannot expand times the ears hammering into a groove and can't slide. So the steels are still being dragged up to the rear bumper, as if it was one warp clutch steel would do the same thing almost, but to break an ankle looking for N, sure.

But the physics are different for the outer hub and inner splines.
Same-Same. Upon collapse, and under load, it's like an upright stack of domino's, one falls into the next one and so forth. The 'ears' of both plates line up and lock as one. So both center and outer receive equal hammering by the ears.. Kind of see how we worked two variables here? Groove bang and the eyes growing wide is one with stuck plates in their grooves, and a warp of a plate taking up such a narrow collapse, N is a bitch to find.

Where 30 is a shaft stabilizer. Where 28 is being pulled by the crank with a row of chains, it's a lot of weight. Where 20 bolts to 21 and that says rear wheel is chained to this shaft. Where any steel and friction have ears on the one diameter, and none on the other diameter.



With the grooves at the end of the clutch center, are we looking at a cocking of the shaft with a now loose clutch outer basket? Only a steel plate knows for sure, meaning, no ears left. But I sort of doubt it was caused by the ears/tangs, but the smooth side of the frictions and the possible wobble at 30 being broke at a spoke(s)?

And third is how much pack is left from the original stack height? The stack is compressing those springs. When the pack wears down, the springs grow and lose locking tension of the pack, and there is your slip higher up making more HP.

Not sure if their is any play but I'm going to definitely check when I get home thank you for the info

I can move that shaft back and forth pretty easy it doesn't sound good

No sir, that is no good you shouldn't be able to move it up/down, side-to-side, or in/out.

Does it move up and down and side to side too? Even a little and don't be shy there's a lot of torque on it and if theres any play then you probably need to open that trans up and have a look. Hopefully, its just the bearing!

It does move up and down very little

If it’s moving, the bearings are bad unfortunately. That may be causing or contributing to your issue.

Mine did the same and it started eating seals, leaking and the movement, would cause the clutch to slip. It’s worse it 4th gear because the gears are helical cut, which causes side loading of the main shaft and walks the clutch open.

Dogs/breast nipples; go into a slot of a freewheeler. A shaft has shims against the bearing, as do the frwheelers, so there is no slop when the dog enters the slot, or the frwheel moves away from the dog's entry and now pops out of gear going into a helical cut, and here it pushes the basket out, or the pushrod out it causes slip? Is it:

A. I better walk this one more time.
B. Maybe reverse the engineering if A does not work.
C. Not here, because up there it only works one way is a gearbox/dog/shim, no matter the cut.

X to Y my bearing cage.carrier move:
Call X the up and down, and call Y the in and out. We are talking a ball bearing at each end of a shaft here. A roller bearing does not have in and out movement, nor up and down. It's the end of the shaft you're holding. If you pull it out ever so little in the Y direction, you might feel the shaft slide in the bearing, but the shim washers give just enough clearance to float for oil between the washers, and the clearance for heat expansion, not to move too far away from gear dog to frwheel engagement.

With X, you can't move that shaft up and down one bit. Because of the design of a bearing, and cage 30. But say a web is broken, then the X movement is to think of a compass and start moving in those other 3 angles. 28 is clutch outer so that puppy floats with clutch in, and out. So if you call that a loose problem, no. You compass 20 like you are pulling/pushing out a stump, the wheel comes off the ground kind of test for movement. There should be none.

And inspection wise, were is the smooth side of the clutch score, and where are the other clutch plates that should have their teeth sheered off. But if you stacked each plate back again, you'll eventually see the center's exposure right next to the next plate and who is it? A steel or friction is next to cover over the shaved peaks of the clutch center. Get it?

No, it faces the pressure plate. Sort of universal. I think shovelheads were stamped with an 'out' stamped on the steels. This showed the sharp side facing the pressure plate. Japanese have the flat side facing the pressure plate. Ready? The CBX Honda has the pressure plate towards the transmission. And when I noticed the sharp side always faces the pressure plate... that's how you walk up to any bike and know the direction of assembly. Yes, drag racers faced the steels towards the trans, but hd, cbx, jap bike for bike faces the pressure plate. I'm not about to re-engineer the memory collapse. It only assembles one way.
