Got the pulley off this arv - didn't have a puller i used a long brass drift and some light taps, not ideal i know but i didn't hurt anything. Looks like my old man put some antiseize compound on the shaft about 10 years ago when replacing the rings. I thought ide may as well split the case to see what it was like inside - no surprises and clean as a whiste. Got the old seal out just waiting on the new one.

cheers
