power steering gearbox and pump

[454HO]

Is there anything I should do to the gearbox while I have it off the truck, besides cleaning the gunk off, painting it and replacing the rag joint? Are there any seals or wear items that I should check? It seemed to work fine except for a bad fluid leak which I think was the high pressure hose. I do have a new hose.

And for the pump, same question... anything I should do to it while it's off the truck? I do want to replace the pulley. It has a bad dent on the inside belt groove and will throw the belt. How do I get the pulley off? It looks like a press fit and I may need a special puller.
