I ended up purchasing the special wrench for the big shaft nut, biggest part is having something to hold the shaft from turning when you first break it loose. Also the water pump mounting bolts are three different lengths, so keep track of which ones go where. I also found some Dow Corning 111 silcon grease handy to hold the pump
O-Ring gasket in place when it was being mounted.

I also had problems with removing the fan when I changed the water pump on my truck. But, when I replaced the pump on my dads truck, he had talked to a diesel mechanic, and he informed him of a simple way to get the fan off. He said to take an air chisel with the flat blade and place it toward one of the corners of the nut and squeeze the trigger and it will come right off. So I tried it and within 15 seconds I had his fan off. That trick worked like a charm for me. Hope this helps

removing the radiator and shroud give a lot more room to work
I also replaced the thermostat as the housing gasket is part of it

I bought this one 65k ago and it still is working fine. Airtex makes water pumps for the big three auto makers. Don't let ford mark these up to $300 and sell it to you. I paid $92 with shipping.
