The fitting instructions on their auction are:
"Simply warm in the oven until to hot to touch. Then pick up with an oven glove an slide on the shaft. Cool with water. Not only shrunk like the factory ones these also come fitted with a grub screw to secure to the shaft."

thats on the older version pulleys from a few years ago these days all the new ones from Alta / m7 / helix etc all have 2 parts and are self centering and bolt onto the hub with a pressure system and require no heating of the hub i can speak for all makes but since the 3 i listed are the most popular
