Got this 416S some time back and just now getting around to the deck issues. It has a 48" deck and all three spindles are VERY hard to turn. Pulled the center/drive spindle out this morning. The deck belt pulley was rusted through, so no saving it. But I got the spindle apart finally. I started pressing things apart about 9AM. It's all stripped now. Time to take another off!
I will get bearings with only one side shielded and add a grease zerk when it goes back together. No more of this stupid configuration.
