  • sweep shims

    Have new synthetic decks installed on 3 lanes due to water damage recently. (wish we never bothered, should have injected and sanded )
    Have noticed on one lane the sweep rubs against the side of the pin deck. Not good. Tried adding shims to push the sweep bar across, but couldnt get enough clearance so lifted up catwalk. Found that where the sweep is mounted onto the machine frame, several c washers had been added on one side to push the sweep arm closer to the pin deck. This must have been done by the installers or manufactures i guess to compensate for a problem. So removed the shims, but the piston bolt inevetably caught on the machine frame badly. To compensate for this I reversed the bolt so the nut would be on the inside and the thin flat head on the outside, thus not catching the machine. This in turn has given enough clearance so the sweep doesnt catch the pin deck.
    Bring me the freshest "Mean Green" known to man! Juice on!

      the other fix is to redrill the sweep front and put a plate to reposition it. There is no actual side to side adjustment.the c washers were probably added to stop the sweep top arm rubbing on the machine frame when it runs through to the 7-10 line.try running it to ensure it is still clear.
      nice fix though.

        It is common for mechanics to shim the sweep saddle blocks to correct a sweep that is hitting the frame or table, or rubbing the pindeck. Sound like someone put a bolt in backwards and shimmed to keep the bolt from hitting the frame.

        Another problem could be the side to side positioning of the machine, a quick check of this can be done as follows.

        Mark a pencil line front to rear on the pindeck throught the 1 pin and 5 pin centerline.

        Put the table at BDC in a spotting mode without pins.

        Hang a plumb bob fron the center of the 1 pin butt plate in the bin and see where it lines up with the pencil line on the pindeck, then do the same from the 5 pin.

        This will give you a good idea if the machine is too far left or right of center in relation to he pindeck.

        If you install the newer 82-90 style sweep mounts the holes for the sweep board are slotted and provide a little side to side adjustment of the sweep bar. I have extended the slots on some machine to provide greater adjustment.

        Please.....follow the instructions!!
