I raised the mower with a jack and removed the deck drive belt from the damaged spindle. Removed the blade from the damaged spindle, 15/16 socket used to remove the blade. I then removed the four bolts, 3/8 socket used for this step, that attached the spindle to the deck. Removed the damaged spindle from the deck, replaced it with the ne w spindle, bolted it into place on the deck. I then reattached the blade to the new spindle, replaced the deck drive belt, lowered the mower onto the ground and was ready to mow.
