    I have a Prestige 23 Simplicity lawn mower. I changed the transmission drive belt and don’t know if I put the pulley just above the electric clutch back on correctly . The pulley can be put on either way , and schematics don’t really show part orientation. The is a note that the chamfer on part goes up. The way I installed the top pulley comes within a 1/4″ to touching the bottom side of the frame. I believe this is correct? but want to make sure it doesn’t go the opposite way , which would leave about 3/4″ from the top of the pulley to the bottom of the frame. Can you help verify?
