what pulley does the crankshaft pulley bolt onto?

my van is having its engine replaced at the moment and the guy doing it says that he needs the pulley that the crankshaft pulley bolts onto so he can put it back together.

he doesn't seem to know what it's called, and i certainly don't either!

the original pulley was removed by the first garage who looked at it and it's still on their desk but i can't get it back as i'm working.

i've ordered the main crankshaft pulley but he says he needs "the one that bolts onto" as well - can anyone tell me what it's called? cos it's nigh-on impossible to get a part you don't know the name of from the internet!

I'm guessing that it is the crankshaft pulley for the timingbelt that sits inside the timing belt cover. The other pulley is for the external drive belts and it outside the timing cover - hope this helps.

thanks - i gave up trying to google it in the end and went and retreived the old one!
