Thanks, I'll give it a try when I get home next month; otherwise I'll send it back to Erik for repair.

Of all the traditional diesels, PAW's must be the most difficult there is to unscrew the backplate. It's designed to be removed with the aid of a UK 10P coin IIRC.
This almost never works for me.
Heating the rear of the engine is most difficult 'cause if you heat the crankcase the backplate will also expand.
One foolproof technique I found is to carefully grasp the backplate rim in a 3-jaw chuck of a lathe and place a towel over the engine.
Twist the chuck and engine in appropriate opposite directions, gently tightening the chuck till it just grips.
So far it's worked every time.
