Garage door won't open
Took off the cover of my Craftsman 1/2 HP garagedoor opener and there was a ton of white "sawdust" like material. Sure it was from the stripped horizontal rotor. Loosened all the screws to take that assembly out but realized I still have the vertical bar engaged by the pulley above the assembly. Do I have to undo the pulley too?
Many thanks in advance,
