The plastic gear in my CRAFTSMAN 139.53973SRT garage door opener needs to be replaced.
I can buy the replacement part without any problem.
But since this is the first time I am doing this, my questions are:
- Is it possible to replace this gear
without unmounting the garage door opener? - If this isn't possible, how do I unmount the garage door opener with minimum effort and time investment?

I found the answer at http://www.thathomesite.com/forums/load/garages/msg0321575526348.html?38 - here it is:
First off you don't have to replace the worm gear. Second, you need to make sure that the bushings in the gear kit are not worn. You can tell by looking and the very top of the unit, you will see ground up metal, or on the top of your drive gear will have a bunch of ground up metal. If this is the case you will need to get a 41C4220A which is the complete gear kit.
Otherwise replacing the gear is a cinch.
Check the bushing in the motor housing that the gear shaft slides through, sometimes this has to be replaced but, very rarely in my experiences.
Don't worry about using anything else in that box.
