      Happy New Year One and All!

      I recently picked up a 1955 Oliver Commander and am in the process of giving it the old once-over. The flywheel nut appears to be made of brass and is weirdly shaped leaving me to believe that a specialized tool is required to remove it. Since it is brass, I don’t want to heat it up to remove it. I also don’t want to use pliers or vice grips for the same reason. I also do not possess the special tool.

      So, how should I go about getting the flywheel nut off? I was thinking maybe a small strap wrench on the nut with a large strap wrench on the flywheel, but thought someone here might have a better idea.

      Thanks!

          That sure looks like a Merc nut. Possibly different size though???

            Wouldn’t be surprising if it is a Merc nut — ChrisCraft was the first to make the Commander and they only sold their outboard business to Oliver because they were threatened with a lawsuit from Mercury for several patent infringements, or so the story goes…………………..

              I Kevin, good to hear from you! Do you have any big sockets? My KF7 mercury flywheel nut came right off with a 1 1/4 socket. Maybe mine is weird or something but you could try one on yours.

                If you have some scrap rubber material, wrap the nut good and use a pipe wrench. I use a piece of serpentine belt, a leftover piece from my homemade strap wrench.

                If you have too many, AND not enough, you're a collector.

                    Good for taking it off. but make one to torque it on.
                    flat steel and 4 bolts for pins then weld a nut on top for wrench and torque.

                      Ah, very good point! I was so wrapped up in figuring out how to get the darn thing off that I forgot that I would need to eventually get it back on again!
