i have a 98 Coleman Seapine that has an Atwood 7916-II that I’m trying to replace the blower motor on. Problem is, I suck at this stuff and I can’t figure out how to get the motor out. I removed the Allen screw, but it won’t come off the fan wheel. I just can’t get the end off. Can someone help understand how this sucker comes off? Are the two holes in the bottom for hidden screws?
