Newbie here. Pulling my camper home tonight with my '96 F250 diesel with 268,000 miles, three things happened - parking brake light went on, cruise control stopped working, and brakes got really firm but weak. Talked to a guy who has had a bunch of powerstokes, we figured it was the vacuum pump. I checked under the hood, sure enough the serpentine belt was squeaking on the pump. Tried to get home, but ended up tossing the serpentine belt when the bearing went on the shaft of the vacuum pump. The pulley no longer lines up with the path of the belt, the shaft is bent, the bearing is gone, I was almost able to pull the pulley & shaft assembly out with no tools.

So I did the "one mile at a time" shoulder drive, keeping it from overheating until I could get it into a parking lot.

I'm at a relative's house tonight. I have no tools with. I really need to take care of it in the morning and get home. I'm fairly mechanically inclined - I'm confident I could replace the whole assembly if a ford dealership has the parts needed. At the very least the bearing and shaft are done for. It is possible the pulley and the pump are functional, but I'm ok with replacing the whole assembly due to the age of the pump and the simplicity of replacing all of it.

Question -

What tools do I need to replace the pump?

(pliers for the tube, 10mm C-wrench (or gear wrench?)

Do I need a pulley puller? Or can I get the whole assembly together?

What tools for the serpentine belt tensioner?
