Before I fit my billet crank pulley I thought I'd check one thing.

When you tap it on with a rubber hammer should the pulley face sit flush with the crank end?

If it doesn't sit flat is it ok to use the nut to pull it on?

The pulley will sit about 5mm away from flush with the end of the crank as it bottoms out on the oil slinger. You shouldn't need anything more than a reasonable thwack with a mallet should it not want to go on - if you are needing to pull it on with the nut then you have a problem. If it goes on about 10mm, then won't move, pull it back off and pay attention to the keyway area, aftermarket pulleys OFTEN need a file or two to get them onto the nose of the crank - don't be scared of this.

Another thing to check if it won't go on is the outer diameter of the pulley. Have a look at the inside diameter of the case - is the pulley eating into it? If so it is also acceptable to take some of the outer diameter of the pulley until it fits - be wary of taking to much off though.
