  • Interlocks AAAHHHHHH!!!!!

    Hello everyone, I know its been awhile.
    Looking for some suggestions.
    We have combo motors of course(duh) in GE(national) & AMF(national). Have bad sweep motor drift. [img]/content/btubb/images/%%GRAEMLIN_URL%%/mad.gif[/img] Leading to, you guessed it Interlocks!!!
    Besides changing all 4 carbon brakes in the AMF moter(done that) & GE motor even worse, what else should I be looking at to fix this.
    Ordering new motor is an option, BUT you know the powers that be (be cost effective).
    And oh 82/70's(c)
    Thanks for ANYTHING!!!! [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img]

    If the motors wont help solve it, I would look to either the gearbox or the chassis. All the motors in the world wont help a dying worm gear in your gearbox. Try swapping gearboxes with the one next to it. Also, check the state of your contactors in the chassis. If the lower ones are shot, you may not get good braking. I would personally lean towards the gearbox though.
    The impossible often has a kind of integrity to it which the merely improbable lacks.

      Pinmonkey is on it... assuming the problem is NOT the gears in the gearbox, your lower contacts may be the culprit. Check the motor capacitors as well... they not only help start the motor, they give that last-second "boost" to the braking. If the caps are going bad, the motor will not brake effectively.

      If it is a gearbox problem, you can get away for a SHORT while by shimming the lower end of the motor head, but it's not a longterm fix... it could overheat or destroy a motor if left like that. Running them shimmed for a couple weeks to get you out of a bind wouldn't hurt them... just don't leave 'em like that. It puts more strain on the motor during running, but allows the motor to help with braking.

      Most times, it's recommended to move a drifting gearbox from the table over to the sweep... if the sweep is drifting, it usually means the gearbox is in dire need of a rebuild.

        GE's are netorious for gearbox drift. You can shim the bearbox istelf, but that will reguire tearing the whole box apart, and if you are going to do that, might as well follow Gman and rebiuld it while you are there.

          Chassis I'd check first... Bad C-1 pins can do it as well as bad braking contacts for the sweep... Also as mentioned the capacitors come into play and also the gearbox... One of these will be the problem almost guaranteed! Good luck and keep us posted!
          All I want in life is to turn wrenches and climb around pinsetters/pinspotters again :/

            Had the same problem not to long ago. Check the plug at the motor for a broken wire or bad pin.

              Thanks guys, some areas to look at. Ohh failed to mention, fresh out of AMF training school in August but been at it for 3 years now. Schooling kicked in and being that it takes practically no time to change capacitors, changed both CSM1 &amp; CSM2. No change!!
              Gear box here I come!!!
              Thanks again, I'll keep you posted.

                if its a minor drift adjust the sc lever out 1 turn will give should stop the interlocking. then you have time to work on stoping the drift.

                  I'm not sure what did it, maybe a combo of all.
                  Changed both cap...'s, drained gearbox &amp; refilled, changed all 4 pins &amp; sockets in C-1, checked (s)cams for 1st &amp; 2nd guard.

                    Disconnect one side of capacitor screws. With Ohms set at 10,000. Using an anolog meter [one with needle face you should get a reading of 0 ohms and a rise to about 150,000 Ohms. Short out terminals to discharge capacitor and switch black and red leads of meter to check inverse of first test. AC caps need to be checked in both polarities.

                      <font size="2" face="Verdana, Helvetica, sans-serif">I would be willing to bet that your C-1 may have been at least partially to blame. Sometimes those pins get oxidation on them and don't connect well. When that happens, you get one of two things:

                      1 Fireworks... which is the usual way. The C1 plug seems to favor going out with a bang... a pretty big one.

                      2 Drift / Erratic operation... You don't see it nearly as much as the C-1 blowing up, but occasionally it does happen. The contacts just cease to work.
