Garage door opener Do repair instructions come with the part? It is part number 41C4220A for a Craftsman model 13953615SR. Thank you
I diagnosed the problem as a worn worm gear in my Craftsman Model 13953615SR 1/2HP Garage Door opener. It appears the complete assembly 41C4220A may be a better choice rather than just the worm gear alone since it's only $8.00 extra. I'm looking for step by step instructions to properly replace the worn parts. Are there any torque requirements?
