Primary upgrade time!
That Spectro golden 80 is really good stuff, but you can use ATF type-f fluid now w/ the baker comp. father in law noticed a difference making the switch couple years back.
OK now pressing out the clutch bearing, just picked out the biggest press plug that fit inside of the clutch basket bore:
Next thing I did was reinstall the old clutch bearing into the stock hub for practice - no issues, just wanted to feel what it felt like when the bearing bottomed out on the lip inside the clutch basket - pretty obvious increase in pressure and even a change in sound.
Now when I did it for real I pulled the new clutch bearing out of the freezer and heated up the Evo clutch hub a bit with a heat gun. I also used a little lube on the OD of the clutch bearing and bore of the Evo clutch basket. I then picked out a press plug that supported the OD of the bearing but fit inside the clutch basket bore. You can not see it, but the underside of the clutch basket is supported by large press plugs against the internal bore area to prevent damage to clutch basket ears:
Installing the new clutch bearing required a touch more pressure and made more noise going in. I think that was probably normal because it was a new bearing vs the old one that had already logged ~7000 miles in the clutch basket.

And now the Bandit clutch hub on the left, stock right. You can see one of the reasons Bandit has 280% of the stock friction area(smaller ID of the hub leaves more area for friction area):

Now is when things slowed down and got more difficult. When you press the clutch hub into the clutch basket you need to support the ID of the newly installed bearing which is a about 1/8" wide rim but you cannot have anything too small or it will get in the way of the part of the clutch hub that comes through the bearing.
Had a 36 mm socket that seemed to be OK but the edges on it were rounded and the clutch basket had a hard time staying level on it. Anyway don't want to bore yall too much but tried to find something at Lowes, found something close and spent about a hour trying to grind the inside of it - blah, blah, blah, gave up and went back to the 36mm socket.
I decided to do the first ~ 3/4" of the press with a plug that covered the hole but supported the bearing ID real well. Next I used my primary locking tool across the support plate of the press with the 36mm socket on top:
With this setup I could get underneath the support plate looking up to insure everything stays centered and I was able to complete the clutch hub installation...
Now somebody can tell me the easy way.
Mine is about .060" - double the allowed tolerance.
After some time I decided to take a measurement of where the starter gear is to the outside edge of the clutch basket's primary chain gear teeth. I did this for the Evo then the old stock basket. Can you guess? The Evo measurement is about .060" less.
Tomorrow I will recheck my measurements then probably talk to Baker - I think they can mill down the motor extension shaft to bring me in tolerance.
I'm tired....
