Unlike other posters, I've ruined a few sets of bearing in a PW bb.
I've sent it back to Phil too. I now just buy 30 dollar Shimano sealed
bb's.
But you could give this a try:
Put the crank bolt or a sacrificial equivalent on one side of the bb
axle and tap the bolt with a nice ball peen hammer to drive out the
opposite bearing while supporting the outer edge of the bb housing in
a vise. Flip and use the axle to drive out the other bearing. If the
bearing comes apart, us a piece of appropriately sized copper pipe to
fashion the equivalent of a fork crown race removal tool to drive out
the outer race. Or just wing it with a long drift.
Purchase appropriately sized bearings and press them into the bb
housing using the vise, the old bearings, or an appropriately sized
socket (you want to drive the bearing in by the outer race, but you
don't want to deform it or the housing). Don't forget the axle before
you press in the second bearing!
That's how I used to do it on my VW bug.
