It appears to me in the gear pictures that someone (previous owner) pounded like a lunatic on it with key in keyway that should not have been there.
Looks like the damage to the gear was from the pump shaft pin.
It couldn't go in keyway so, it made it's own pounded out hole next to it.
If that is what happened it is a wonder the thing ran at all.
Get a used gear and a new PIN.
IMHO !!!!
Follow the timing instructions I posted earlier and you should be good to go.
Hagen Tractor is another salvage operation that may have the gear.
It should not be hard to find one.
Another option is to buy a used pump shaft that has the woodruff key in it and use the gear you have.
Edited to add ---> The gear should not have a a key in the keyway .
The parts book clearly shows it in the pump shaft.
Doesn't matter which model pump. They all are in the shaft.
