  • Crankshaft pulley bolt - p/n 034 105 229a not available

    Dear All,

    I have a RS2 ADU Motor and Audi Dealers say it is NLA, anyone know what size bolt and what strength steel it is made of?

    Regards
    George

      It's M18x1.5, 65mm long but unless it's damaged it can be re-used

        Hi Mike,

        Is this a stretch bolt?

        Regards

          If it can be re-used it won't be a stretch bolt.

            It's a tough one. 12.9 grade. Avoid the febi copy as it has a much thinner collar.

              Should the bolt be used with a washer / diamond washer ?

                  As John has hinted at, it's not a stretch bolt. Tightened to 450 Nm

                    Could be worth getting some custom ones made to the correct dimensions. Any interest?

                        The same for the SWAG one? I was checking for 3b s2, Febi and Swag both popped up in the webshops.
