So let me get this straight to make sure i understand.


There is a chamfer on the stock oil pump gear (you have to take the oil pump cover off to access it correct?).


And I need to make that same chamfer on the jp double roller crank gear.


Both the side of the oil pump gear (the one that i'm copying)and the timing chain crank gear (the one I am modifing) are located on the back side of the engine (twards the trasmission side)

Correct?


Whay cant I just copy the stock timing chain crank gear?
