Clutch alignment tool & how thick should clutch disc be

[macx]

Got the trans off, was very stubborn. Had to use small pry bars on opposite sides and wiggle it back and forth to get the trans shaft out of the clutch.

Splines look to be in very good condition both inside the clutch disc and on the trans input shaft. (

But the inside splines on the clutch disc had some kind of black dry material that looked like old dried up grease or
something, but was totally dry. I believe that's what caused the trans input shaft to stick inside the clutch splines.
Brushed and cleaned with compressed air.

What could I use for an alignment tool if I disassemble the clutch? I've got an old one I used to use on muscle car
clutches, but I don't imagine there's any way that would fit - I suppose the shaft has got to fit snugly in the flywheel
and mine for sure isn't metric on the end.

I tried to look up the BMW tool # on the A&S website but, of course, it won't come up.

There must be something available - would appreciate info!

Now, how thick should the clutch disc be? After cleaning the clutch, I took a close look and found the rear side of
the lining seems to be maybe .020" thinner than the front side. Stacking some feeler gauges, the rear / thinner side
appears to be about .085" to .090" thick. The bike has 32k on it. I'm trying to avoid spending any unnecessary cash
right now, am laid off and need to conserve (mortgage and all that of course has priority) BUT don't want to pass up
a chance to renew the clutch if it doesn't have too many miles left on it, either.

Appreciate any info from anyone that's replaced a clutch and knows how thick a new one is, etc.

They have a tool for 20 bucks. Also available is a lube kit.

Yes, I had just found that from a link in a post that came up from a search on here.

I like the looks of that street clutch, but that'll have to wait.

Actually, either a stock one at $165 or the RSR one at $325 is going to have to wait.
I think I'll run this one out, should last a couple years at my amount of riding, then
will be time to check splines and maybe get some of that special lube anyway.

Anyone ever try their lube? Looks like it might last longer.

Thx

EDIT: Also found this from San Jose BMW

I tried to buy to buy a street clutch from them last year. Waited over four months, then canceled the order and put the old disc back on with Moly60 as lube. Has anyone else been able to buy something from rbracing?

Service manual sets wear limits at 4.8 mm for the clutch disc, measured at the rivets(?) Confusing to me, I would think that if your at the rivets, the disc would be toast. I measured mine at 6mm, so likewise thought I could get another year or so out of it.

Here's clipping from the pdf service manual
