I've just removed one by using a 14 mm tap, just putting a couple of turns on the sludge trap and working it out using the tap as a puller. Very basic, but it worked.
I went to do the same on the second crank I have and the tap isn't a large enough diameter!
I'm going to make a dowel with a spring loaded peg to pick up the oil delivery hole. Bit like the system used on the quick adjustable alloy crutches and walking sticks you get.

Hope that helps.
Cheers John
