Took the deck off of the mower,removed the blade assembly, removed the mandrel cover, Removed the nut above the mandrel pulley, and removed the pulley. Removed the four bolts holding the mandrel to the deck. Removed the broken mandrel assembly. Placed the new mandrel in place, used the four self tapping bolts to attach the new mandrel. Placed the washer and the new mandrel pulley and secured them with the nut. Replaced the mandrel cover. Attached the blade assembly. Then installed the deck back on the mower. Make sure you take a picture of make a note how the belt was routed.
The parts I ordered were not overly expensive, arrived at my house quickly and were correct. The repair project was easier than I expected due to the good service from the parts vendor.

The new pulley had the splines that fit over the splines on the mandrel / spindle. The splines on the old one was worn out and wouldn't grip the splines on the mandrel I replaced.
This new one has been working perfectly!
Put blade belt around new pulley and just used channel locks to tight the nut down on the pulley (to the mandrel). Then put tension on the blade belt again and she was ready to mow!
Thanks for the FAST shipping too guys!

Middle mower blade mandrel upper bearing broke and caused damaged to mandrel and housing

1. Removed mower deck from tractor.
2. Lean mower deck against a upright surface to give you access to both upper and underneath mower deck
3. Removed middle mower blade.
4. Removed middle mandrel unit.
5. Cleaned underneath shroud.
6. Reinstalled underneath shroud.
7. Installed new mandrel unit.
8. Reinstalled mower deck to tractor.
9. Reinstalled mower deck belt.
With the new non grease mandrel I won't have to struggle trying to get the grease gun on to the old grease fitting.
One more thing while I had the mower deck off and leaning to access underneath I took my pressure washer and cleaned the bottom of mower deck where caked on grass and debris had built up. It's worth the extra few minutes to do this while you have easy access to it.
