I'm attempting to replace the motor of my attic fan. I've disconnected everything else, but I noticed after I removed the nuts on the support bars that I can't pull the fan and motor through the opening because the supports get in the way.
The supports appear to be attached with the kind of bolts that I'm not going to be able to remove without causing irreparable damage.
It's important that I remove the whole assembly as I need to measure the distance between the center of the fan and the motor to ensure when I put it back together, there aren't any collision issues.
The only other alternative I'm seeing is to go on the roof and remove the metal shell on top of the fan so that I can pull it out that way. Is this the normal means of removal or can this be safely removed another way?
