Pilot bearing install depth

[JL1RX7]

I can't seem to find any specs in the '89 FSM that tells you how deep into the E-shaft that the pilot bearing is supposed to be installed. Does anyone know?

I just had to yank my transmission because the pilot bearing failed; since it came out in pieces (inner race & needle bearings at least), I can't really be sure it was installed correctly to begin with.

I suppose I can buy the special tool Mazda has that makes installing the pilot bearing an idiot-proof, no measurement affair, but I'd much rather just slowly tap it in using a suitable sized socket or bearing driver I already have, and take measurements until it's in far enough.
