1g Oil Pump Question

[Coder24]

I just got my new oil pump in the mail and its JDM style. But what I was wondering is was what is this gear in the attached picture? The gear off to the left. My JDM pump doesnt have that. is that bad? or what?

It looks like they just put it there to ship it and the sproket for the oil pump. Or its just a larger than normal sproket for the balance shaft

So tell me, what exactly is a "JDM style" oil pump?

Anywho, the bolt hole where that sprocket in the picture is put is incorrect. If you're running balance shafts, there is an offset tensioner pulley that goes there. That sprocket sure looks like the oil pump sprocket that should be on the oil pump shaft.

Just make sure that if you're not running balance shafts that you have the stubby shaft and the castle plug installed correctly. And locktite the oil pump nut, cause that's a PITA if it comes off.

what i meant by that was my oil pump is JDM. Like the ad said the gears are jsut cut differently. Not really sure but that pump there in the pic is a topline. where that gear is in that picture on mine is justa tiny bolt hole. this is my oil pump.
