After tighten clutch hub there is about .020 gap allowing the hub to have slack. Bearings are in great shape. Installed a baker compensator.

The clutch hub will not tighten down completely on the shaft. It appears as if the spacer is too thin but that makes no sense since this is the first time it has been taken apart. The shaft has no play in it. Checking it was a dial indicator I can get approximately .004 movement with a crowbar. Any ideas?

I am guessing the clutch hub was off because you installed the Baker Compensator?  Was the clutch hub bearing replaced and maybe not pressed back into the hub all the way?

I did not replace the bearing.  I cannot find any play in it at all.  It seems kind of weird to me how sloppy the hub is on the shaft. But there is no damage to either one.  I pulled it back apart because the primary had got extremely hot to the point that the clutch stopped working.

The clutch hub should seat firmly on the trans shaft, no shims from the factory. The hub should not be sloppy fit on the shaft. The trans shaft determines the position of the hub and the hub determines the position of the clutch shell.

I agree with @maniacmac (no shim or spacer).

@Fatboyhd I just took a look at the manual to be sure because in your first post you said "It appears as if the spacer is too thin but that makes no sense since this is the first time it has been taken apart."

The clutch hub does not use a spacer.

Here is a link to your 2010 CVO Ultra’s clutch hub. That model uses a hydraulic clutch.

It mentions a thrust washer and a spring washer that is built into hub assembly.  They are not separate parts that are sold individually.

What was said in the above quote is probably pretty much the issue. You are likely not seated firmly on the trans shaft. If you had a worn out Compensator that needed changing then it is possible that the movement that the old Compensator was allowing has damaged the trans shaft and you are not able to seat the clutch hub due to that damage.
