Hey all, After looking for pictures/videos like the rest of you, I decided to document my SM420 rebuild with videos and posted them to You Tube. I'm good with a wrench, but I'm a newbie to a transmission rebuild. I have the shop manual and the Novak instructions. Once you get it opened up it's pretty easy to see what's going on. Long video, full overview: Clutch hub and clutch keys: Main shaft overview: Pressing on the clutch hub: Input shaft needle bearings:
I hope these help. This site has provided lots of helpful info for me, I wanted to contribute back. Thanks, Greg
