R35 GT-R Nissan OEM GT-R Oil Pump with AP Oil Pump ISR Treatment

The nissan oil pump in itself is quite remarkable. Most people probably probably do not realize that the pump is not only pumping oil, it is also scavenging it. The pump incorporates some of the latest oil pump rotor designs that we see in some of the aftermarket wet and dry sump pumps. Nissan has obviously put alot of time into its design.

It appears that at some point during the design process Nissan realized that they had to scale back on costs. Nissan had gone about 90% with the machining of the parts and said the hell with it for the rest. The scavenge gearset just like the pumping gearset has a small squared off section off the radius that does not want to mesh together. If anyone has felt one of these in hand, you will feel a small bind ever "x" amount of degrees. This is the od of the inner gear not wanting to mesh with the small squared area of the id of the outer gear. (Squared area only on outer gears)


On the Scavenge side of the pump, there is a small area 360 degrees in which the inner gear is abrading a small ridge on the housing. It is from facing of the gear and then not deburring it then after. It is not on both sides of the gear, but does need to be taken care of.
