  • Sweep Rocker Arm

    Where the sweep rocker arm connects to the 3116 tie rod on the 7 side the bolt head is hitting the Stabilizing Link 3238 and the Pin Bearing 3103. Is this the pillow block bearing wearing and causing it to slide to the seven pin side? Can you grind down the bolt or replace it with a clevis pin for a quick fix before fixing it properly?
    Well we're safe for now. Thank God we're in a Bowling Center.

    You can grind the bolt and install a Nylock Jam Nut to conserve space.

    A couple things to check:

    1. Remove the sweep bar at the mounts. Does it seem as if the sweep brackets are applying outward pressure to the links? If so, the sweep bar brackets may be bent. This is very common with the newer 90-style sweep bar brackets, but still possible with slide bar type also.

    2. With the bar still off, disconnect the tie rod at the rear of the link assy., allowing the link to swing freely. As you manually move the link back & forth, does it still hit?
    Also, in the relaxed position, is the center of the link/s front "knuckle" centered in the flat gutter? In other words, does the link hang straight down? If not, shimming at the saddles may be in order.

    Of course, check for twisted individual links.

      Perhaps under the pantograph link washers may need to be added or removed?
      If all else fails, don't worry as it will wear away soon, and be a thing on the past. [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

        Tried shimming the saddles. A 2 inch clevis pin ended up giving me the clearance needed. Will check the centering of the knuckle next.
