  • broken sweep links

    we had two of the short sweep links break and they look easy enough to change butt [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] I would get the pin in on one side then the other side would only go in about half way,I fought with these bouncing the links all over the place pulling and pushing on them and I finally got the pin all the way in after about 35 minutes [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img] is there a easy way to get the pins in when they don't want to go in,the pin would go right in with one link at a time but when there put together the pin only goes in a 1/4 to half way.
    anybody have any ideas.

    Always test the pins through the bushings before installing them... sometimes the bushings are pushed out-of-round when they are driven into the aluminum casting.

    Your pin may also have been dented or burred. use a flat file to dress the ends, then sand them smooth.

    I've also seen the ends of the arms become bent from being dropped or whatever, they may be bent slightly, so when you're installing them, the pinway isn't fully straight.

    Bushings also have some variation to them...I've had to take a coarse round file and file the bushings slightly to match them up. A small amount of filing will not affect the operation of the joint, or cause excessive play in it... just don't get carried away.

      gman,
      the problem doesn't seem to be with the pin or the bushings [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] the pin goes in both sides of the link when I'M holding it in my hand the problem is when one side is connected then the other side won't go in [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] and the pin goes in easy on the ones still connected on the machine easy,the problem is when I try to connect the two when they interlink together.
      sorry I guess I need to learn the names of the parts better,so you guys can understand what I'M talking about. [img]/content/btubb/images/%%GRAEMLIN_URL%%/frown.gif[/img]

        Make yourself a guide out of an old pin. Grind a taper on one end of it so that it can get started even when the bushings are not aligned (like a drift punch). Oil it and tap it in first, with the real pin right behind it.

          Ken, sounds to me like you are putting the links together wrong. There is an order of assembly to the links. Drop the sweep on the machine next to where you changed the link. Compare how you assembled the links with the other machine. Make sure you compare 7 pin side to 7 pin side , and 10 side to 10 side.
          Good luck, Mark

            ar,sounds like a good idea what your talking about doing,I'LL try that next time maybe it will be faster then 20-30 minutes to get one pin in.
            the other question I have is are the sweep links put together the same on both sides [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]
            I looked at 20 machines or more and some are put together the same on both sides and some are put together one way on the 7 pin side and a different way on the 10 side.
            can anybody tell me how they should be.
            thanks.

              Ken, when replacing the short sweep links
              ( sweep arms ) part # 070-003-242 you will notice that on the end of each link,one side of the link is straight, while the other side is angled. When 2 of the links meet, the straight part of the links interlock with each other ,in the center, while the angled part of the links face to the outside .If you invert the connection ,and have the straight part facing out, and the angled part to the inside , the pin will not want to go through.

                i've never really checked on this but i was told that the seems in the links should always line up with the center of the joint.

                  grind down an old pin at one end to about halfway its length to a point like a nail, push this pin in first pushing the new one in behind it .
