The ones that I am looking to replace are 3770509CE and 3993325DJ. Both are single groove, fit a straight shaft with a key, and are held on by a large nut. If your pulleys aren't mounted, could you measure the offset from the back of the pulley to the back of the hub and the pulley diameter? Both of my pulleys are the same dimensionally, but have different part numbers. Yours might work, but I need to know that before I buy them. If it's too much trouble to measure, I understand that, too.

Thanks.
