Im in the process of swapping a 404d out of a 66 4020, with a 404t out of a 7700 combine. Im to the point of trying to figure out what water pump, or fan and pulley and balancer combination will work. the combine balancer will not clear the hyd. pump bracket, and the 4020 fan will not clear the combine water pump. I was hoping someone else would have experience with this swap.
 
Yes, Tim is the resident expert. I just finished a 404 to 466 swap and what I had to do was take everything off the 404 motor and bolt it on the 466. You might look at the 4620 parts though because they are spaced out away from the front of the motor a bit more than the 4020 setup. I had a 4020 for a short time that had a combine 404 but I don't know what parts went into it. I'll paste a pic of the motor below and maybe it will help you.
