Oil pump gear marks?

The two halves of the pump housing has to be lined up properly when you bolt it back together. I believe they have a tool that goes around the O.D. for that. 65'

there is a tool. you can also use a BIG hose clamp. or so what we used to do and put pump together 1st and put it in trans without other guts in it.

Ok thank you!
I put it together on the torque converter hub.
The case is empty so I'll make sure it fits ok.
Something that's also not covered in my book.
It only shows a 727 pump.
