    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?

    See if there is a set screw or two holding the shaft. If not it may be pressed on.

    It would help if I could find a good manual with all the details.

    The two holes are probably for a wheel puller. The puller has a jack screw in the center, and slots on both sides for the pulling screws. The two holes may be tapped, but may be just there to tap, if needed.

    I would soak it with wd40, etc then support the backside of the fan on some wooden blocks and then tap the shaft in the center of the fan with a small punch/rod/bolt to free it up and drive the shaft out of the fan.

    Raycfe has the idea of what needs doing. You could try to have someone applying pressure on the back of the fan with a pry bar while you are tapping the shaft.

    Looks a lot like an older model automotive blower. Those had a set screw on the flat side of the shaft. Over time they would sometimes become seized to the shaft. applying penetrating oil or heat can help free it.

    As others have mentioned. I would do both the wd40 down the shaft let it sit for awhile then do the, have someone hold the fan and tap with a punch light hammer. only on the shaft, light taps. You don't want the tapping to upset the motor.

    Penetrating oil works better then wd 40. Just fyi. Otherwise everyone is right on the money.
