Driven clutch / secondary clutch disassembly for John Deere Gator 6x4

Is that a left hand thread bolt that holds it on the transmission? Thanks.

Did you have to remove the grooved bearing in the center?

Im having the same issue, i had to remove the set screw and with your advice i got it out. Now my 3 jaw puller is struggling to pull it up. I just gotta replace the buttons on the thing so i just want to get it up a bit
