My spindle housing is cracked and I need some help getting it off. So far I've got the deck removed from the mower, the blade and tray off of the broken housing, and the bolts out of the spindle shaft. I'm not sure how to get the hub retainer off. Does it pry off or do you smack the spindle shaft with a hammer until it passes through it and the housing? From the looks of the diagram on the parts breakdown there is a key woodruff that installs into the hub retainer, then after that is a bearing slinger and then the spindle housing.
