front case and oil pump gear question

[herms99gst]

will a 7 bolt oil pump drive gear work on a 6 bolt front case?

To my best recollection from memories of rebuilds from the past. The 6-bolt gears have straight gear teeth, and the 7-bolt gears have helical (slanted) teeth.

I doubt it will work. I would just buy a new pump or gears for the specific engine your building. I know I wouldn't wanna cheap out on a part that is as critical as the oil pump. It could destroy your freshly built engine and you will be back at the same point you were in when you needed a rebuild or worse.

I did not mean the oil pump gears I apologize for the confusion. I meant the gear that's apart of the timing assembly that attaches to the balance shaft stub

No I do not believe they are the same

If you are talking about the oil pump drive gear that the timing belt rides on then IIRC they are the same. The cases are different but it is possible to make a 7 bolt case work on a 6 bolt block with some slight modification.

This gear, correct?

Yes the oil pump gear will work on all the 4G63 engines 6-bolt and 7-bolt. . Sorry for all the confusion on that.

yep that sthe one thanks for the info. It just sucks now that i realized i ordered the wrong tensioner . I purchased a fullt kit from extreme psi and i hit 7 bolt tensioner instead of 6....im a dumba**.
