Looking for advice on how to remove the injector pump. I removed the 3 retaining nuts, as well as the governor cable and found the pump will move about one half inch than stop. After reviewing the parts manual, I see there is a retaining nut on the end of the pump drive shaft so I removed the access plate to the gear sump on the aft end of the injection pump and removed the end nut. There are also 4 bolts on the gear. Do I take those off also and then the gear will slide off? Seems like a nightmarish re-assembly job unless I remove the radiator so I can see if everything is lining up afterwards. Thanks
