  • Axle Nut Not Fully Engaged

    DSC_1691-Small.jpg
    I'm using Grove wheels on my Patrol. When I torque the axle nut down to the correct tightness it doesn't fully engage the axle and is about one thread short. Has anyone else experienced this?

    Don't quote me, but I don't think the castle area is much counted on for stiction. This may be in a manual but I forget, there was still plenty of room for the pin.


    Here's my gear:

    I'm probably wrong, but at least there's a lot of engagement.

      On the inside of the wheel there is a felt washer and a thin metal washer to hold it in place. The felt is to keep dirt out of the wheel axle. Remove the felt and metal washer and you will have enough room for a full engagement of the axle nut. Don't neglect inspecting/cleaning the wheel bearings. The axle need to be 1/4'1/2" longer.

        IMO it’s find how it is. My plane is about the same.

            Did you end up removing the thin washer and felt from the inside of the axle? That would help but would remove some important dust protection, cotter key drilling looks nice.

            No I did not remove those washer from the inside as I, like you, wanted protection in that area from dirt and crap.

            Yes, the cotter key came out super nice! I know a guy with a jig for that! LOL

          Same with my cleavland wheels. Axles are a bit short.

            I kind of think they need to be like that. The axle nuts aren't very thick, and the hole for the cotter pin isn't that large. Not much engagement range between can't get the pin in, and the pin is proud of the nut and isn't keep it from turning.

              Well one should drill the cotter key hole to match the nut so having a little longer axle would be desirable.

              LOL. My gear is basically assembled and covered, but I haven't tried to pin the nut because I will wait till it is ready to fly to lube it up. I guess I didn't realize they weren't drilled.

              I made a nice jig for drilling the axle precisely to match the cotter key. Rob Caldwell used it and your welcome to borrow it when you get to that point.

            I had cleaveland wheels on hand when making my axles. The plans length seemed short to me so I added a quarter inch, glad I did.
