Lincoln C2OZ-6600-A Oil Pump Assembly

Unbolt and lower the oil pan. Remove the oil pick-up tube-to-main bearing cap nut. Remove the oil pump pick-up tube mounting bolts. Remove the oil pump mounting bolts and lower the oil pump assembly into the oil pan and lift them both out together. If the pump is faulty, or you suspect that it's faulty, install a new one - do not attempt to repair the original. As complete oil pumps, new or remanufactured, have become more inexpensive, reliable and readily available, service parts for oil pump overhaul/repair have become increasingly difficult and unnecessary to find. Prime the oil pump prior to installation. Pour clean oil into the pick-up and turn the pump shaft by hand. If you separated the pump from the pick-up tube, use a new gasket and tighten the bolts securely when reattaching them. As the pump is reinstalled, fit the oil pump driveshaft into the pump. It must seat all the way. DO NOT try to force it. If it doesn't align, turn the pump slightly and try again. Install the mounting bolts/nut and tighten them.
