Vented Spindle Housing 532128774

I removed the blade bolt and washer from the spindle and removed the blade. I then remove the deck from the mower. Remove the nut from the mandrel pulley and remove the pulley. I then remove the three bolts holding the mandrel to the deck, and the mandrel came right off. I used a brass rod to punch the spindle from the mandrel from the top. Then I used a block of wood and tapped the spindle into the new housing. I used the same block of wood to tap in the top bearing. I then placed the the new housing up to the deck and used the same screws to mount the mandrel. The mandrel is not threaded, but the screws are self tapping. I placed the pulley on the spindle and then tightened the nut down on the pulley. I installed the blade and then attached the deck to the mower.

Re-drilled mounting holes to accept a 3/8" bolts. Bolt head fit in casting as designed. The through hole can be tapped, but drilling a clear hole to fit the 3/8" make the repair quicker. Then mount the mandrel with washer, lock washer, nut on the top side.

(Be sure to check both housings if you have more than one blade. I only ordered one to replace the one that was DESTROYED. Once I got under the deck I realized the other one was cracked as well. It just hadn't completely failed yet. Had to wait another week to get the 2nd one in before the tractor was fully operational again.)
