  • binding sweep

    ok guys, this one has me stumped. I have a sweep that binds on it's way down causing it to jerk and slam down. It runs fine sweeping the deck and returning to zero though. Here's what I tried so far:
    Checked telescoping links for binds
    disconnected sweep from motor and moved it by hand
    and can't feel any binds
    I didn't change the motor because I thought if the gearbox was bad, it would bind more then just from 0 to 66, am I wrong?

    What am I missing here? Thanks guys.
    Give me a hammer and some duct tape and I can fix it!

    Mr Pinspotter:

    It may not actually be a bind. I've seen this happen where the key/keyway is very sloppy allowing the crank arm to fall ahead of the drive shaft. Check the condition of the key/keyway.

    Another scenario is the crank arm is too close to the mounting plate.

      Check bumper part #000 023 279 if it isn't urethane it might be sticking to link assbly.

        IT SOUNDS LIKE THE KEY ON THE CHRANK ARM SHAFT. HAD THIS HAPPEN TO ME A COUPLE OF MONTHS BACK AND IT DROVE ME NUTS TRYING TO FIND THE PROBLEM. I ONLY FOUND IT WHEN I THOUGHT IT WAS THE MOTOR AND WENT TO CHANGE IT THAT I NOTICED THAT THE SHAFT MOVED ALITTLE TOO MUCH.

          I dug a little further into this today. I found that I can crank the sweep down a little and the sweep doesn't move all that much and then push on it and it will drop down to where it should be in relation to how far the shaft has turned. I have a whole set of links put together and ready to go and I'm gonna put that on tomorrow and see what happens. I think the bind is on the 10 pin side. As for the keyway thing, it's not anymore sloppy then any of my other ones. The crank arm moves a little bit, but not enough to cause it to get ahead of the shaft.

            Do you have a bolt or pin hitting the frame on the way down?

              Or what about a broken pillow block on the 10 pin side...
              So it goes.

                Well guys as it turns out, it was a sloppy key way in the crank arm. The first time a checked this I didn't think it was that bad, but I losened the bolt and I could move it about a 1/4 inch. Replaced the crank arm and the key, and it runs smooth as silk.

                    Broken Pillow Block would make the sweep jump not slam.

                      A major symptom of a broken pillow block is the rake not going back far enough to clear the pindeck. :p

                        Ill correct myself here...

                        <font size="2" face="Verdana, Helvetica, sans-serif">Kat finished what i wanted to say... But on the way back from 180 the sweep will most likely jump and then slam at 270.
