    Tekno Wheel Hex on M6 Axles Depth issue

    i am sure this has been answered already but have not been able to find the answer.

    i have m6 tekno shafts on my slash and the wheel hex is too narrow, leaving a little gap inbetween the lock nut and the wheel when i tighten it down. i put washers in to help but want a more permanent solution.

    i noticed the wheel hexs from tekno are 4mm deep and the stock 4x4 are 5mm deep. anyone know of an aluminum hex that will work for the tekno axles?

    thanks!

    So I have found this part on traxxas.com - crazy price for these, think I will just buy a set of hexs and then my own drill bit.
    https://traxxas.com/products/parts/6869

    Anyone know the depth/thickness (not bore) of these hex's? is it 5mm or 6mm?

    Thanks

    They are 6.6mm thick. The key hole looks .5mm off center but there is ridge on the inner side of the hex.

    I think many people who are going this far with the Slash 4x4 are also going to 17mm hex conversion. Might be worth doing at this time.

    The 1mm difference is just fine and a non issue

    anyone use TKR1654X tekno hexs and if they have any play in their wheels? i have aluminum hexs on my slash that i thought were tekno but now im unsure. the 1mm is a big difference on my current wheel hexs because it is starting to groove the wheel hub between the locknut and wheel. the amount of play in my wheels is really bad.

    The Tekno TKR1654X does not leave any play - a perfect hold on both stock wheels and Stampede 4x4 wheels.

    I have the same problem enare vat has using the stock plastic Tekno hexes that come with the M6 kit. They are not as wide as the stock traxxas 4x4 hexes. I'm using ProLine Renegade wheels and have to add 2 of the Traxxas teflon spacers between the wheel hub and hex to get the wheel tight. Would someone please measure the width of the aluminum TKR1654X please and thank you?

    so i purchased the traxxas part 6869 and did not actually have to drill out the bore. however, the set scre does not line up with the holes on the tekno axles so i cannot use the part. hopefully my lhs is ok with me returning the opened part.

    i just ordered the tekno part TKR1654X so we will see of those work.

    I am happy to report that the TKR1654X fits perfectly.

    It comes with 8 washers which makes for a snug fit using 2 washers on each axle between the pin and the bearing.

    Here is a photo of the new part compared to what I was using:





    Here is a photo of the Tekno hex next to the stock slash hex.

    Why not forget all these troubles , time , n money and just put on reverse rims , that gives u a wider wheel base , and call it good instead of worrying what's going on while your trying to enjoy yourself ? ( Just sayn )
