  • cam adjustments

    Hi all. What is the best (or your personal ways) of completely adjusting including using new switches? I've not had to adjust cams too often, little tweak here and there, but to start from scratch... never done. Thank you all for your input! [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]
    Don't mind me, what you read is invisible.

    Re: cam adjustments

    Adjust the gaps using the gap tool.. I believe AMF calls it a 'sweep cam sdjustment' tool, but it works for the table cams as well. One side is large, and the other is small. You want your gaps on all 6 cams to trip the microswitch when the large side is inserted, and not trip it when the small side is inserted (adjust on the flat part of each cam)

    You then set your stop points by loosening the clamp stud and rotating the cam until everything stops where it should. I set the table so that the nylon roller on the table eccentric ligns up with the shaft that goes through the solenoid assy (flag on one end, shuttle stop on the other) about a pinky size gap.

    On the sweep, I adjust for proper 1st and second guard position.

      Re: cam adjustments

      If totally starting from scratch, I do as mentioned, set your cam gaps properly with the gauge. Then I usually turn to a nearby machine to see about where the cams sit, match them up somewhat closely and tweak from there. Once you're in the ballpark it's not bad.
      All I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/

        try to follow this method.
        rotate the cam to the HIGH points and loosen the jam nut, then individually rotate the screw in, until you hear a click, do not push the screw in as you will get a false position. then roate the screw anti clockwise (OUT) for one complete turn on steel cams or 1 1/2 turns on aluminium ones.nip up the jam nut, not too tight.Do all six cams. Check stopping position of table and adjust cam cluster to obtain desired position by loosening cluster and rotating in desired direction.
        Cycle machine and watch stopping position of sweep at first and second guard and adjust SB cam cluster to obtain desired stopping position at first guard and SA cam cluster to obtain desired stopping position at second guard.
        this way you can tweak without upsetting the stopping/staring positions you set on the micro switches.
        remember to set all switches on the HIGH points of the cam, choose any point on the high sections.

          Sounds like all good info here except, If the switch screws where never loosened/or changed...you need to rotate the cam by (Your Eye) You need no adjustment tool for this.

          I work on some nice old Brunswick A-2 pin setters. Most issues I've come across haven't been to problematic to figure out. But being I can't seem to get it to recreate the issue...
