Hi Guys,
Can anyone tell me
1) How hard one of these is to change, once the flywheel is off
2) what the procedure is, and what tools are needed
3) How much one would be likely to cost?
I'm considering doing it at the same time as my clutch..

Cost will probably be pennies but they can be stubborn to remove. First plan of attack is probably to pack the end of the crank in which the bearing sits with grease until it's full, then drive a section of old gearbox input shaft into the hole. This builds up pressure behind the bearing since the grease won't compress and may well force it out.
Failing that, you need a small pry bar or something with a hook-like end to get behind it and try to pull it out. It's well worth changing given your issues, because they can cause clutch drag if they start to sieze.
A mate of mine had his sieze (well, he was doing donuts on the beach in his Caterham at the time!) and it was just like a broken clutch cable. No way to disengage drive. You could unleash the full power of the engine on it with the clutch floored and it would not free off. When you see the size of them, that's quite remarkable!

The grease method wont work as its a roller bearing so it got gaps round it that let the grease out.
You need a blind bearing puller with a slide hammer or you cut it with a hack saw.

Does anyone have a pic of this bearing in/out of the engine? I'm really not confident - what could I bugger up? :-X

Here's a generic one: http://en.wikipedia.org/wiki/Needle_roller_bearing
Imagine that in a hole in the end of the crank, and the gearbox input shaft passing through the middle of it.
