    Thank you for your response, but I have looked at all of these sites at Rotax and they are not giving enough detail about steps of disassemble assemble, what tools to use, measurements and such. I may have to send it to a certified repaired center, but I like doing mechanical work myself as I have on auto and heavy equipment most of my life. Thanks again for all responses. Gary

    Video for Rotax 503 rebuild

    You can get a 503 rebuild video here http://www.ultralightnews.ca/videos/.
    I can't say if it gives you torque specs, as I haven't actually seen it, but might be helpful to see how its done.

    Thank you, it looks like it might be some help, and worth ordering it's not that expensive.
