Karen : That low a pressure with 5 cans of refrigerant would suggest a restriction in the liquid line section. Since you didn't have a temperature drop across the drier I would bet you indeed have a defective or improper expansion valve. That sensing bulb should fit the area of the suction line it is clamped too. Generaly it locates on the side of the pipe but it probibly won't matter much. After rereading your post you mention only 125 psi discharge pressure yes the compressor could be suspect if it doesn't pump properly due to defective internal parts you would never arrive at the necessary suction pressure due to a lack of capacity. The expansion valve would be wide open and the compressor could never supply enough refrigerant. I would go with the expansion valve first assuming it wasn't opening enough which could cause the discharge pressure to be lower then you would expect . If the new xpansion valve doesen't correct the problem my next suggestion would be to take advantage of the return warranty on your new compressor. I'm sure you made sure the heat damper is shut and the fan is blowing full bore thru the evap coil .
