  • table cycle not finishing

    I have a machine that on first ball it cycles, picks up pins, rakes, but doesn't put the pins back down. It just holds them in the air. It's not waiting for a new set of pins cause the bin is full, so its not a strike detection. I solve this by lifting the table finger switch on the front of the machine and the cycle finishes, rake goes up. It happens about 3-5 times a night. Any sugestions?

    Re: table cycle not finishing

    First thing I would check is my pawl clearance.

    Sounds like you do not have enough clearance and the pawl will not always slip by the link when the table is coming back up.

    Also check your shaft that holds the ass'y together and made sure it isn't moving.

    I see that the new books refer to the pawl as a respot finger and finger spring.

    Can anyone elaborate on the change and why?

      Re: table cycle not finishing

      The way he described it, it sounds like the table never even goes back down to let go of the pins. It just picks them up and stops, as if it were a strike cycle (which he has already deduced that it isn't). This suggests that the problem is not in the pawl adjustment? I'm not sure what you mean by a "table finger switch"??? [img]/content/btubb/images/%%GRAEMLIN_URL%%/confused.gif[/img] Unless you mean the TA1 cam follower. Anyway, it sounds kind of weird. The first thing I would do is change the chassis or switch with another machine and see if the problem switches with it. I'm not sure what else it could be since I'm not a professional 70 mechanic like King or Mike [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img] .

        I agree with Mike.....for the sweep to go back up it must finish the cycle.....so the TB cam makes the sweep go up....

        I would check for:
        1. Binding respot cells.
        2. Bent wireways.
        3. *Shifter link adjustment*

        My guess is the cells are closing too completely.
        The book says back the screw out 4 turns I believe.

        I adjust it so the cells have 1/8 play in the end of the finger slots when completely closed. This is there the bolt attaches them to the cell castings.

          Sounds electrical to me... check your offspot switch and wiring for shorts.

            If the machine is on second ball when you get there it probably is offspot switch or wires as g-man said.

              Opps , I misread Turn-A-Wrench's post. If the problem is what you've described then your problem is electrical.

              If the problem doesn't remedy itself by changing the chassis, then you should look for chafing in the off-spot wiring. But, if the sweep runs through that should eliminate the off-spot circuit.

              Check your timing

              Take some WD-40 and clean your microswitch buttons. Sometimes they get dust inside and hang up.

              It has been a while since I have had table wiring; make sure your table plug is well seated.

                thanks all I will try these things. Also yes the table is staying up. I forgot about the offspot switch thing and the table finger is the TA1 (I think). I'm still learning and am trying to learn names of things. Thanks again. [img]/content/btubb/images/%%GRAEMLIN_URL%%/smile.gif[/img]

                      For the record,
                      Merriam-Webster dictionary Online defines a pawl as:

                      "a pivoted tongue or sliding bolt on one part of a machine that is adapted to fall into notches or interdental spaces on another part (as a ratchet wheel) so as to permit motion in only one direction".

                          Immediate thoughts I got was the offspot switch possibly being bad, or the 2 small bearings in the table drive clevis (the ones with only a sleeve on one side of the bearing) we've had this a few times that turned out to be those bearings. Check them babies out and make sure they're still good [img]/content/btubb/images/%%GRAEMLIN_URL%%/wink.gif[/img]

                            its in the offspot system. Disconnect the wires on the offspot switch that should do it. Most likely a bad switch. I had that same problem on lane 9.

                              1. SB adjustment at 186*
                              2. Loose 26419 housing or 26042 switch
                              3. OS switch or wiring gone to hell
                              4. 048 output or 1699 table shaft teeth worn out, allowing slippage at 180*
                              5. Something in table drive out of lube or worn
                              6. 179 ring gear teeth worn out
                              7. Time delay going/bad connection
                              8. Something else...

                              Does it always have pins hanging, or does it happen on strikes too (assuming you don't have MP's)?

                              Sweep stays at 270*, right?

                              Swap the gearboxes and clean &amp; lube everything on the front end. I'm sure you've already checked out OS and swapped chassis.

                              Let us know what takes care of the problem!
