  • help with a 82-70 table problem

    got 82-70 i got one lane here it set a full rack of pins down just fine but win it goes to pick A spare up the table drops real fast and lower than what it should drop thanks yall

    Sounds like the table drive is stuck in the unlatched position. Watch it after it sets pins and make sure the finger locks in place into the table drive when it stops.
    Failed safety course.Question #1:In case of fire what steps do you take? Apparently 'Friggin long ones!" is the wrong answer.

        After the roll pin breaks in the drive the spring falls out. I drilled all my pins to 1/8" Gets rid of the 1-3 break downs a yr.

          I would say either the table drive eccentric latch has problems or there is a ton of grease in the eccentric notch, or the shuttle operator is not 'releasing' fully after spotting.

                    On the converse, I had a lane where the latch wouldn't lift out and the table never traveled any lower than respot height. It turned out I'd just been overzealous with the grease gun, and grease was oozing slowly out into the notch, creating enough suction on the latch to keep it from lifting. I had to clean that latch with a rag every chance I got for a week!

                        I've been contemplating this issue for the last few days. On face value we have a problem involving the change in the table positioning. Whether or not the table runs to a spotting position or a re-spotting position. The only mechanism that controls this is the table drive and the spotting latch. I ran into a spotting issue the other day. Pins would not be released by the cups. I ran the table down to BDC and it was almost an inch off the deck. So I adjusted the clevis a good 4 turns out. While working around the machine I noticed that the 10 cell had jumped the block and the finger was hanging behind. After replacing the cell I now had a table hitting the deck. Adjusting the clevis back in and I had everything back to normal. How would fingers being blocked cause the table to not drop to it's lowest position?

                          That one makes my brain hurt.

                          The only thing I can think of if one finger jumped a bumper enough to reposition the cell yoke, it's possible that the other finger was in the way of the cup causing a bind and since the spot rod pulls on the table to tilt the cups down, any bind in the cup tilt will result in the table losing some of its downward travel- such as when a pin is wedged in a cup in a way the pin is against the table yoke a won't let the cups tilt- the table never makes it to BDC when this happens. Same idea but not as severe.

                            i agree, to me it sounds like the spring has fallen out and if the table is jolting i would be checking that the cone bearing in the eccentric is not loose or binding
