Removed the mower deck from the riding lawn mower, removed the plastic cover from the deck over the shift bearing house, then removed three bolts holding the shaft and bearings to the deck. Then used the blade while using a air driven impact wrench to remove the top bolt from the shaft. Used the new shaft to mount the new bearings into the shaft housing. The instructions mentioned using a spacer that was required but was not part of the kit or on the old set up. It should have been included in the kit. Reversed the above steps to complete the installation.

Dropped the deck, removed the belt, bolt and Pulley from the top of the Mandel, removed the bolt and blade from the bottom of the Mandel. Then remove the bolts holding the mandrel to the deck and drop the mandrel. Next the shaft was removed but the bottom bearings would not release from the mandrel. I stuck the handle of a socket wrench thru the top of the mandrel and hammered the bearing out. I cleaned the mandrel and installed the new shaft assembly and assembled the other parts in reverse.
