The bearing is a press fit into the crank shaft. A little dab of grease will
help the pilot engage easier. The bearing is a front support bearing (pilot)
for the transmissions input shaft, if you don't put it in, the front bearing
on the transmission will fail a lot sooner than it's supposed to, and you
will get vibrations when running.
The easiest way to see what it does is to: hold a pencil with one hand on
each end and rotate it. Both hands support each end equally and it rotates
smoothly. Now only hold it with one hand on one end and rotate it like you
did before. If you can rotate it the same, your lucky it will more likely
want to spin at your hand correctly and wobble all over the place at the
other end. The end with the hand is the transmission front bearing, the open
end where the pilot bearing is supposed to be. Get it?
i.e. put in the bearing.

Reinstalling transmission in my 55 chevy 1st series.
Does anyone know
if you need to grease the pilot bearing that goes into the
end of crank
shaft, before you install the transmission? Does the bearing
go on the
transmission spline or into the crank when installing? What
does this bearing
do, being that the crank and the transmission spline turn
together?
