Thanks!

From H2Es diagram it looks like the hole is deep enough.

deeper than the 2.225 in his pic or your 2.120

Yes sir! And shims if necessary for the bell face runout .

The drill an tap idea of the pilot bearing housing is to provide an easy means of removal when necessary. With tapped holes all the way through you just use a couple bolts to work it out.

Sorry for all the questions guys. Guess I’m just really thick with this stuff.

Also thanks for the pic of bearing with the tapped holes! I clearly see what IQ52 meant by pusher bolts. Great idea.
