I just ordered a remanufactured CD4E for my 98 Contour SE 2.5L. The rebuilder's documentation states that I must use the "pump shaft" from the old ATX. I have not yet pulled the unit and I won't receive the new unit for about a week. I would like to know what to expect before I pull the unit so I can be prepared for the task. I assume the "pump shaft" in question is the oil pump drive shaft. Can anyone confirm that? Also, does anyone know what is involved in pulling the "pump shaft" from the old unit and installing it in the new unit? Is any disassembly required? Are any special tools required? Any other helpful tips would be greatly appreciated.

THANKS!
