    Hey, i wonder if there are any adapters or ”needlelayers” to fit a 10pin piston on my 12pin eurocilindro crankshaft.
    Maybe something like this:

    Could you tell me the measures?

    Then i will check if i can get those Needlelayers 😉

    Edit: I’ve Checked it with these measures:

    Asgap: 10mm
    Outside: 12mm

    I can’t get those Needlelayers, and i think it will be hard to find those, because 1mm on each side is not much. I only can get with an Outside Measure of 14mm, thats 2mm on each side.

    For a Malossi crank you need to search for 15x15x10 mm.

    The standard needlelayers for a P12 crank are 15x15x12 mm.

    Jarco: Well it’s good to know! thx 🙂

    Daffy#46: It’s 14,9mm on the outside (eurocilindro crank), and it should be 10 on the inside. Dont know the lenght yet tho, will measure tommorow.

    MHR: Great, i take it that it should be the same on eurocilindro? my dad measured it to be 14,9 but either he measured wrong or the layer is supposed to get pressed a bit i guess? Will go ahead and search for 15x15x10 then.
    Thanks a lot!

    I’ve also been looking around to find me a needle bearing of this size. I’ve even been to two specialists (whole suppliers) but they also couldn’t find anything of these measurements in the books.
    The biggest I’ve been able to find was 10 X 14,5 X 15.

    I’m also still looking but in the meantime I had one of these made in 10 X 15 X 15. It is just as strong and capable of high revs, if made of the right material.

    I came, I saw, and I forgot what I was doing...

    Then it’s 10 inside, 14,5 outside and 15 on the wide?

    Would those work? thought since it doesnt have the needles.

    This works just like the old type crankshaft from Piaggio. It works just fine if the measurements of the bearing are right and the material is suited for the purpose.
    The one on the picture is not the right one, it’s just for the illustration. I’ve had mine ‘custom made’.

    Hmm if it works as good then it sounds great! What materials are proper to use then?

    I believe bronze is the right stuff.

    Didn’t understand to much, google translate isn’t that accurate 🙁 But if i understood some right, then he made a adapater so you could use a normal 10 pin, like 2 parts instead of 1? too bad i can’t understand the instructions

    Its the same as the one they made for Tonni, only this is more like a how to to do it yourself.
    The google translations is shitty indeed, but seeing the pictures i cant imagine its realy difficult to do. ( with the right tools. )
