Hello, everyone. I am sorry to have to ask your help again concerning the reassembly of the 440 in my '78 D300. I bought and installed the non-A/C brackets for the P/S pump and mounted the pump. I have a 4-groove front pulley. The P/S pump pulley wants to run in the second engine pulley groove, counting from the groove closest to the engine. The problem is that both the P/S pump and the alternator want to run in the first two grooves of the front pulley, while my old water pump pulley only engages the outer two grooves of the front pulley, so there is nothing to drive the water pump. I guess I have the wrong water pump pulley, and need a deeper one?? But even then, there's only gonna be room for one more groove before it hits the water pump, so I am going to need another groove because the alternator and P/S pump need to be driven by different grooves, right?? Pictures attached. I sure would appreciate it if some of you 440 gurus could tell me what I am doing wrong. Thank you very kindly.
