I can´t find the tightening torque to magnetic plug (new model) in the engine manuals. Can anyone help me ?
Thank You,

    Hi Arnaldo,

    You should download all the Rotax manuals here on the Rotax site. A number of torques not listed in the Line or Heavy maint. manuals are listed in the Parts manual. They are a special torque. So if you don't see a torque listed in the maint. manual go right to the parts manual.
    Okay so here's the deal. The new torque is 18 ft/lbs = 24.4 NM = 216 in/lbs.
    The old torque was 25NM = 222 in/lbs. which = 18.5 ft/lbs

    So it is now on the books as 18 ft/lbs or 25NM (?) or 216 in/lbs. I know it's the new math.

    Line Maint manual edition 3 Rev. 1 12-20-00 sec 12.1

    So it was mentioned somewhere else, I think it was here on Rotax-Owners.com, that the torque of the magnetic plug as specified by the factory was maybe incorrect. Because you are reinstalling the plug into oliy threads and not the clean, dry threads as described in AC43-14. So what do you think?
    And on a similar subject do we have to purge the oil system when we remove and inspect the magnetic plug?

    Torque doesn't change ans no purge necessary.
