Oil Pump Info - erling66 - 11-05-2013 I have gathered a few pumps and decided to share the info. I found that all 601/2/3/4/5 and 6 pumps will fit any of the engines(and even some of the gasoline engine pumps as well) the difference is in the pump gears, they are the same dia but different length so they give different volume. It appears that they all have the same pressure regulating spring. The back cover(with oil pick up) will interchange on the different pumps. I have noticed 2 different chain gears, the will interchange but you will need a chain with different length. So it is quite easy to upgrade to a higher flowing pump if you are adding a turbo or 2 the pumps are from top left: 603NA(big chain gear, 30mm pump gear) 603T(small chain gear, 33mm pump gear) 606NA w124(?chain gear, 37mm pump gear) 604(small Chain gear, 28mm pump gear) 602NA(big chain gear, 25mm pump gear) I hope someone has some info about 605NA and T RE: Oil Pump Info - mantahead - 11-07-2013 interesting, i had two om605 turbo engines stripped before and noticed the oil pumps where different, but i never looked much further.
