Input Shaft Seal Repair sleave

Thanks!
So, to install you would pull the bearing retainer and press this onto the shaft with the flanged end going on first till it bottoms out then re-install the bearing retainer?
I assume the other sources of the leak can be fixed with a sealer and plumber tape?

note: I have gear oil running down my clutch fork, so I think its coming from somwhere up top.
