Fan and top pulley is held on with a single nut on the transaxle input shaft. Nut is removed, and the fan and pulley will come off. The old pulley bolts removed, and new fan bolted on the old pulley, then re-install the pulley and the nut. The only problem is getting to the nut! With little room to work in, the trans axle has to be removed from the frame and lowered to give access to the nut.
