2. Removed large nut on top to remove pulley.
3. Removed 4 bolts holding mandrel and dropped mandrel and blade through deck.
4.Install blade on new mandrel. New mandrel is not threaded where mounting bolts go. Best thing is to thread mounting holes with existing bolts before mounting mandrel to the deck, easier than trying to thread them while holding it in place.
5. Install mandrel. Put pulley back on top, install large nut, make sure to hold blade from the bottom to get a good seat on large nut. Put belt back on.
6. Put cover on, put everything back in place.
7. Started mower. Everything works great!
