  • Durabin bouncing the 8.

    Still new to the Durabin.

    Here's what it's doing.



    -Removed the last two rollers on the trip arms, to slow the pin down as it seats.
    -Removed the rear, trip arm bumper, in an effort to seat the pin... FIRMLY!

    Some improvement, not enough for us.


    What's causing these 'bounce outs'?


    The Dizzy for this/these lanes has just undergone a PinCup cleaning and restore. Smooth and fast. Then upchucks an 8 now and then only on durabin lanes.

      Isn't that a known issue with the DB and I thought AMF had a kit you bolted in there to stop that, but im not sure.

        Occasionally we have a pin bounce up on the origional bin and shuttle assembly. I have actually seen a pin do a complete 180 degree flip after hitting the bin and shuttle ie. pin fed base first, hitting the bin and shuttle and doing a 1/2 revolution in the air and landing in the bin with the head facing the front of the machine. A 1/8 to 1/4 turn of the safety link normally solves the problem.

          It looks to be dropping it square in the bin.

          Anyone got pics of the fix?

            Interesting.

            The only time I ever saw something like that happen was when there were 2 pins in the 8 bin and the dizzy caught on the top one as it indexed from the 8 to the 5 pin position.

            But, this doesn't seem to be happening in your case from looking at the way the rest of the pins are loaded.

              Prevent the problems. Don't do crash repairs.

                It's on the QA portal under bulletins...

                "Description: Durabin 8 pin pocket blocks 612-088-209


                The profile of the Durabin in the area of the 8 pin has changed to help keep a second layer 8 pin properly lined
                up. Previously, an occasional 8 pin would bounce backwards and come in contact with the distributor trip levers causing poor indexing or pin pile-ups.


                Owners of earlier model Durabin II’s can modify their equipment in the field with the Durabin 8 Pin block
                Kit. This product is not recommended for the original Durabin due to the difference in wall thickness."​

                    We have one pair of Durabins and had these same issues. Kit looks like a whole lot of nothing, but they really work. Calls vanished after install.

                      Thank You Sirs.


                      Second question I have, while we're talkin dura,... MAN! these things are LOUD!!
                      I'm just too old schooool I guess. If you had your bin assembly right, all bumpers in place and butt-guide/head-guide tight, the old 8270 bin was really quiet.

                      Here, we have 7 of 22 with the durabin upgrade.
                      When the house fires up for practice.... I hear this



                      Has any tried sprayfoam or truck bedlinder to quiet them down?

                        I should have stated this picture is staged, BUT! This is the state I have found it, when I can catch it before it piles-up. I too have assumed that this happens when double stacked. I've still yet to actually witness it happen. After it's piled-up the stack is at the 2 or 4, with the problem 8 jammed up under the dizzy's carriage.
                        We know what's happening (we think we know anyway ), I was sure one of you guys had already solved the puzzle.

                            Spot on Rivmike. There are now cameras available for use in cars that have a small screen included and record to an SD card or similar. No more needing to run coax cables back to a VCR. Cameras are the best way to catch recurring problems. Its the old thing as long as you sit there and watch it it won't happen, turn away and bingo there it goes.

                              I had always assumed this problem was caused by the front of the dizzy being too low and it was catching and 'dragging' the second 8 pin as the dizzy indexed from the 8 to the 5.

                              From memory (I haven't worked at that center for nearly a year), I think I actually saw it happen once or twice.

                              The problem did seem to disappear (or was greatly reduced) by raising the fronts of the dizzys a little (just a flat washer or two added to the spacers for the 2 bolts).
