  • How do I smooth out a sweep?

    Hey people!

    I have an 82-70 sweep that doesn't run so smooth anymore. I replaced a coasting motor, adjusted cams, and adjusted all the rods. It still binds up on the ball return side (even machine). For the life of me I cannot get it to run smooth....ugh

    any thoughts? I need help [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

    Kinda need more info on the bind.
    Is it jerky when it runs? Can you feel a bind when cranked by hand? At what degrees is the bind? Does it make any squeaks when running?
    "Where are we going, and why are we in a hand basket?"

      hey man the best thing that I do is to look at another machine that is running smooth and look very closly each sweep will have a sweet spot look and soon you'll see the answer looking you in the face.

        Sounds like your bumper is sticking #000-023-216. Clean it, shave a layer off, or replace it.

          if your talkin about binding up to the point of lock (motor overload)....check sweep rocker arm for break outs of the bolt inserts.

          if you're talkin about the "driving over a rocky road look" but never locking. . . .over travel will cause this, as will the "5 pin line" adjustments bein opposite for both sides.

          or is it the other way around in reverse??

            well it's more like a sudden jerking motion as the sweep comes up from the 270 position.
            I've compared to other machines and all I end up doing is re-adjusting all day long.

            I'll keep trying your ideas and hopefully someday I'll get it figured out.

              check and see if you have any slop in the sweep gearbox and also check the rod ends too

                Check the sweep crank arm on the drive shaft for tightness.

                  Beat me to it King, I was just gonna suggest the same thing. We just had 2 of em get loose on us. Tightened em and they run like new [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

                  All I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/

                    If its only on one side like you say check for a broken pillow block strap. Also check the teloscoping ASSY, maybe the rod is bent. Its not a spongy shock mount is it?
                    Make sure all links are oiled.
