Hi Jeff
I would try and remove the bearing. First make a sample and stick together with
638. Then heat using a heat gun and beat it apart. This way you know heat
required.
Perhaps you can get it off without hurting the bearing? My first attempt
would be to use a collar like this:
https://www.mcmaster.com/collars/set-screw-two-piece-shaft-collars/
Idea is leave a few thousands clearance to flap cross tube so it slides. if you
can't get exact size, go slightly under-size and bore on a lathe. Install the
collar, slide towards fuse, heat cross tube, slide collar against the bearing
and using a 3 or 4 jaw slide hammer, grab the OD of the collar and try and
hammer it out. You may need to use a blowtorch which will kill your paint and
probably damage bearing. If that doesn't work, you could turn a shaft with a
step, so perhaps .020" step larger than the bearing bore. Then drill and tap
for slide hammer threads. Now for the magic, make it out of Brass and slit an X
using a hack saw (2 cuts) the flange about 3/8" deep. Now you can squeeze the
OD of the flange down so it fits inside the bearing, when you screw in the
slide hammer, the threads will expand the flange and allow you to grab the
bearing! Again heat and beat. You need to mess with an undercut that allows for
contraction. Good luck Ron P. BTW as far as Europa, lift pins and flap drive
pins, good idea to sand them starting with 1,000 grit wet dry and get up to
3,000 grit, then polish them. Before assembly clean pins and bores and put the
thinnest of thin amount of grease on them. Using a make up applicator works
great, can get at Drug Stores:

Do same for spar pins.
