Pilot bearing removal ?

Well George, guess which technique I'll use ? 

This one is too funny to pass. And it has the very benefit that I have all
the "tools" here, right down to the 5 lbs hammer. Let's just hope that the
bearing isn't "capped" as on the 20VT engines.

Geraint ? How is your precision manipulating a heavy hammer ? Better than
mine ?

More to come !

Gone chunking cotton rags...
