Nissan RB Oil Pump Drive Collars (also known as Crank Collars) are precision CNC machined.
Replaces the narrow oil pump drive originally machined on earlier Nissan R32 RB26DETT all RB20DET, RB25DET, RB30E and RB30ET crankshafts.
These can also be used to replace a worn oil pump drive on R32, R33 and R34 RB26DETT crankshafts.
The collar provides full engagement on the inner oil pump gear which greatly reduces the likelihood of oil pump gear breakage in these engines
Each collar is supplied with instructions and grub screws.
These collars do require machining to the crank to fit and can not be fitted in place.
