2. Removed the nut on top of the pulley using an impact gun. The immediate torque on the nut busts it free so there is no need to lock the blade in place or try to other wise hold it from spinning, as with a wrench.
3. The shaft and blade were damaged so I left the blade attached to the shaft and discarded both to the scrap pile. You would need to remove the blade first, if it is still good and will be reused.
4. Clean the area where the bearing rests before installing the new shaft. lots of debris there after 5 years of mowing.
5. Insert the shaft into the spindle housing.
6. Make sure you install the little spacer on the top of the shaft then the pulley and thread the nut on.
7. Again using the impact drive the nut on tight.
8. Add grease. The bearing comes dry. I filled the spindle with about 1/2 of a tube of lithium multipurpose grease.
9. Install the new or reused blade.
10. Install the belt guard. The center spindle had no guard.
Center blade sheared off on a rock.
