An even easier way is to use a tapered drift with the OD same size as the
housing ID, wood or metal. Install the seal in the houising and then force
the drift through the seal from the inside of the housing. This will force
the seal into position and enlarge the ID to accept the flange spigot. Then
back it up inside with a socket of same OD size and push the socket through
the seal, push rear flange forward displacing the socket and the flange is
now in position inside the felt seal. Works a treat. The tapered drift is
easier to use than three screwdrivers.
Assemble as Lawrie says below.

It is possible to poke the seal into the groove if you are patient and push
from each side as you push outwards from the middle. Obviously, there isn't
room for three screwdrives in there at once, so it is a slow, incremental
task.
Once the seal is actually seated in the groove, we take a deep socket of the
same outside diameter as the part of the rear flange that is to ride inside
the seal. Using a long extension bar and the aid of a screwdriver to get the
seal over the socket, gently work the socket into the seal. Then, from the
other direction, push the socket out with the rear flange so that the latter
is now seated inside the tail housing, inside the felt seal.
After that it is a relatively simple task to slide the tailshaft housing
onto the back of the gearbox, making sure the flange engages with the
mainshaft splines without slipping backwards out of the seal. Then tighten
the flange securing nut and you'll find you do not have seal pinched between
the flange and the guard.
Just be sure all the other parts are inside the tail housing and on the
mainshaft in the correct order before you do this. It's a nuisance to find a
part left on the bench after going to all this trouble to get the seal in
place!

P.S. We have not found a modern seal that is a suitable replacement for the
felt.
