RB Billet Spline Driven Oil Pump Gears
Suits Nissan RB engines with Nissan N1 Oil Pumps (77mm Outer Gear)
Outer Gear Diameter: 77mm / Thickness: 10.96mm
This kit includes:
- Spline Collar
- Inner Oil Pump Gear
- Outer Oil Pump Gear
This set replaces the standard N1 Oil Pump Gears which are powdered metal.
Now with Isotropic Micro Finish!
Both the gears and spline collar are Precision machined from EN26 Tool steel, featuring an N1 spec ‚wave‘ profile for higher flow. These gears have been proven under extremely harsh conditions & stress.
Spline driven gears are a much better, positive drive and more effective way to drive the Nissan oil pump.
This type of setup is used in all OEM Toyota 1JZ and 2JZ oil pumps ( See pics below ) and numerous other OEM engines. There is no „chatter“ or „back lash“ which is common with the OEM RB drive setup.
