    SunTour downtube shifters, help in putting together

    Hi!

    I just got an set of old SunTour downtube shifters i plan to use on my road frame with downtube bosses.
    But i dont know how to put the things together. And if the shifter set is complete. Anyone can have a look on the picture, and maybe can tell me in what order i shall mount the parts? Or if the set is complete?
    Tnks!

    Working from the mouting boss outward, try this sequence:
    1) backing plate (large square cutout);
    2) lever;
    3) round washer;
    4) washer with flat-sided hole;
    5) domed spring-loaded washer;
    6) cover plate;
    7) bolt

    OLD equipment? I have similar, older SunTour levers on the PKN-10, and the respective original equipment Campag. equivalents on the Capo and the Bianchi. With a little care, high-quality friction downtube levers last indefinitely. The Campags. on the Capo are just now nicely broken in .

    Now that I'm old and prone to memory lapses, I've started video-taping and photographing things as I disassemble them. I don't do it for everything... just for gadgets that have a lot of parts that have to be re-assembled in a specific order.

    LOL. I do this too. It's a great thing to have a digital camera. Almost as good as having bar-cons.

    If you have Cyclone shifters, it is:

    1) backing plate (large square cutout);
    2) thin dished washer;
    3) lever;
    4) thin flat washer;
    5) retainer/washer;
    6) domed spring-loaded washer, saw toothed edge;
    7) threaded cover plate;
