It is not "Good Practice" to hammer on the water pump. Especially during reassembly. The seal is very brittle and hammering can crack it. It is much easier on everything to press it smoothly together. If you don't have a press take it to someone that has one and give him a beer. You don't want to put the whole engine back together and find out the water pump seal is bad because you hammered it. You can also damage the bearings and that won't become evident for a little while. Pinning the pulley is a bad idea because if you don't get it exactly right on the shaft you have to remove the pin, reset the pulley, and redrill the shaft. Better to get the bolt-on pulley. Or better yet just get the right pump AND pulley from a "D" vender!
