The factory Tech Bulletin merely says to drive the spindle out until the bull gear woodruff key is exposed, remove the key, and then continue until the spindle is out. Based on experience with other equipment (mostly Land Rovers), I'm making a spindle puller/installer out of a length of 3/4" all thread, some nuts, washers, 3/8" thick flat bar (cut into disks) and mechanical tubing. Whichever method you use, the spindle head bearing cone will push out the dust cover behind the spindle nose. The other pieces come out after the spindle is removed, if they need to come out. The left bearing cone will pull or push put the left end dust cover. And so on.
