How do you change the vacuum pump on a 1997 7.3 diesel

Customer Question

How do you change the vacuum pump on a 1997 7.3 diesel

Remove the belt, then you'll need a special tool ( a power steering pulley puller) to remove the pulley from the pump. Disconnect the vacuum hose from the pump and then remove the three bolts attaching the pump to the bracket. Ford manual states that you must remove fan and shroud to allow pulley removal, but I have always been able to do this without removal of fan and shroud. If your PS pulley puller is too long and hits the shroud, then you should be able to reach behind the pulley and remove the three mounting bolts, remove the pump from the bracket and then swap the pulley to the new pump. Use the power steering pulley installer tool to reinstall the pulley, it screws into the threads in the center of the pulley shaft. See info below. Steve
