First 741 rebuild with pics of pattern

2.774, you want to move the pinion towards the yoke.

When you measured your depth, did you check the depth of the case carrier bearing race bore and make a suitable adjustment? They are not always 1/2 and 1/2 in case/cap. the pinion depth measurement is from the center of the carrier bore.

With where you are now, it's a moot point. Something to consider for next time.
