I tried grease packing even tho I had the puller in
the basement because it had worked several times
before on American iron.  All I got from 3 or 4
attempts was a face full of grease.  No movement at
all.

The bearing should not be totally bottomed out in the
crank hole.  I used an attachment that came with the
slide hammer and first hit moved it 1/4" and second
hit yanked it right out.  It destroys the old bearing.
 BTW the "hammer" on mine is about 10 lbs.  Last
resort?  Cut the cage with a small, sharp cold chisel.
 The cage is very light gauge steel.  I noticed how
easily the cage deformed and collapsed when I used the
hammer puller.

Good luck

ps-did you remember to mark your flywheels orientation?
