Anyone get pulleys for another engine to match their wheelhorse?

[WH656 9]

Just curious what the pulleys are called that are on the crank?  Are they called v-pulleys or is there a name for them?  Where would we buy them? I got a predator while I rebuild the 6 hp Tecky over the winter..  Debating whether to take off the old pulleys or just add new ones on the predator.. Sorry I am just learning.   wh 656.
