I've been trying to take it slow, and ask questions first (what a concept, eh??!!). It's been a long time since I've dived this deep into something, and I'm sure it's easy once you know the secret!

Vikki, I did take your advice and removed the four bolts, but it did not separate. I guess I didn't know it was a two piece affair. I think if I put something like the right size wood block behind the pulley section and (GENTLY!) tap the snout with a hammer, it should break loose. Failing that, a puller should separate them, yes?

Again, thanks for everybody's patience and assistance, there's been a couple times when I just wanted to throw in the towel, but walking away and taking a break seems to be helping.
