BlazNT, thanks for the parts numbers. I will see if i can confirm what I have.
7394, interesting. I would be happy just in solving the sticking in gear situation.
I was looking under my Craftsman LT 1000 and Poulan last night. The pulleys that engage the belts are different. Although I did not actually measure them, the Craftsman pulley is about 3 to 4 inches in diameter and the Poulan is about 2 inches. The bolts in the Poulan pulleys are very loose. I wounder if the guy I got these mowers from swapped the pulleys for some reason. I will have to find a manual for each machine.
