crankshaft pully?

Hi all,
I think my timing belt has slipped(ref white smoke by Toad)can anyone tell me which pully/part number I need to replace.Is it the bottom one affixed to crankshaft inside the timing case I think.Is it fixed by woodruff key?Am I going to face any major problems tackling this task?
Help urgently needed as i have to order parts now to fix next week.Also what other parts/gaskets do i require?
Many thanks Stevek

Thanks Trewy,
Thats a very good article.
Next question is;
If the crankshaft pully and damper moves how does this effect the camshaft/fuel pump timing?
Regards Stevek

depends which way it moves
If just the crankshaft pulley has moved, then it will throw out the camshaft and IP by the same amount, either way.
