Deere injector pump swap 4039 t to 4045

I have a non running generator with a 4039t turbo engine that cranks good but no fuel to injectors. I took inlet part of stana dyne pump apart and found shaft snapped in half. I do have a Deere 4045 pump that was rebuilt. Question is could I run a 4039 t pump on a 4045 pump? I'm assuming fuel amount would be close, injector pressure would be same big question is would timing be the same as one engine has a longer stroke.
