Housing mandrel broke again. The blade hits the ground or something that stops it and the torque breaks the housing mount from the deck.

Drop the deck. Seems like a lot but well worth it to pull a few pins and get it out where you can work on it. Remove housing mandrel. Pop the bearings and rod out and put them in the new one. Then bolt it back on the deck and put the deck back on the mower.

Great part

The part was received quickly, installation went easy, only problem THE BOLT FROM THE OLD MANDREL WAS TOO SMALL TO REATTACH THE BLADE.. MIGHT NEED TO INCLUDE THE BOLT ASSEMBLY NEEDED TO FINISH!!! HAD TO REMOVE THE MANDREL, GO TO THE HARDWARE STORE, FIND A BOLT, THEN REATTACH MANDREL AND BLADE.
