  • 82/70 trouble again!

    Thanks to all for their input re my last post. That seemed to fix part of the problem.

    Now, after 3 or 4 frames, sweep drops and table lowers about 10inches and stops. What now?!?!?!

    Re: 82/70 trouble again!

    Since you say it happens every so often leads me to believe you are experiencing sweep coast....causing an interlock. Cycle the pi$$ out of the machine and observe from the front. when the sweep drops to 66, make sure it is not drifting towards the pins. If it drifts past 86, it will open the SC circuit and cause an interlock when TB is engaged at 105.

    Couple of things to check:
    -Verify problem is not in chassis by moving to another lane and see if problem follows.
    -Check sockets on C1 harness for burnt pins on braking circuit for sweep.
    -Slop in sweep gearbox.
    -Too much resistance on SB cam microswitch (responisble for sweep braking at 66)
    -Failing CSM-1 and/or CSM-2

      looking from the front of the machine. anytime the far right Table (TB), and far right Sweep cam (SC) switches levers are out at the same time the machine "interlocks" either your sweep cam lever is way too far in, which causes it to engage too early at guard position, or as Kat Explained your sweep motor is drifting. Change Chassis, Change Capacitors and/or Motor to prevent drifitng if the sweep cams dont seem to be out of adjustment

        Sweep interlock was correct answer. Thanks again all!!!!!!!
