I've had it with this 904, about to give up!

Really...very interesting. The ball is a little malformed now. Maybe I should try to find one that's the same size to replace it? Surface looks good, now that you point it out it looks gouged in the pic but I just checked and it must have been the light or something. I can't for the life of me find the bolts in any of my transmission parts bins, I guess the ones from my spare trans are going to get snagged.

Yea, I have a drawer of them here from another life.
Ace hardware is a good place to get another one, and be sure to stake it in.

If you can put a straight edge on that pump face where that mark is and it's flat it'll be fine.
Just for kicks pull those pump gears out (Keep them facing the same way they are now) and if the other side of the pump gear area looks as good, I wouldn't have a worry in the world about it.

Re grease it with trans lube or vaseline on both sides and in between the gears and go.
Hint: A fair amount of lube around and inside the gears will insure the fastest possible pump prime when the car fires off.
