  • 70 & 90's Spotting Cup and Yoke Assy.

    Can this part be installed backward? Part #070-002-624 ARM ACT YOKE ASY.



    If this is not a fluke or the arm bent out of shape; the answer is yes. The keyway slot does not line up with the bolt slot. Installeds one way,the cups look like this when the Lever Assy. Spot cam bottoms out in the Arm Act Yoke.



    Like this when reversed.


    This is easier to find sitting on a table in your shop rather than in the machine!

    If any of this post is incorrect in any way please advise.
    Tks

    When looking from 7 side, the keyway should always be installed closest to rear of machine (or about the 6:30 position) when the cups are in their relaxed position.

      With the arms that have a part# cast on them…
      Triangle symbol goes to the inside, part number to the outside.

      However, I did have one arm that was miss marked and another that has no marks and another with no part number but the triangle symbol. The rest of my arms are marked correctly.

Many times there are minimum wage guys who never even seen a pinsetter (like me :p )who are responsible for stamping parts, etc. and sometimes things just get through. If I told my help to use arrows and such, they would be overlooking the theory on how things are put together and why...relying too much on others' work. Like carpet belts; we all know they have the "Rotation Arrow", but I always check the seam just to make sure. Check twice, install it once.

          Thanks fellas for posting. Thought we had seen a post where someone had changed a yoke and couldn't get the pins to spot. This very well could have been his problem.

          When you have a tip like this you should post it for the new techs or the guys like me that haven't worked on 70's in 35 years! In the old days the machines ran like sewing machines. We didn't have all this distributor, bin, shuttle and pins be jamming between table and shuttle problems. They ran BETTER than "B" machines!!

            Both of our advice could be questionable. Remember were giving advice to some generation x techs. Next question will be…what position is 6:30 on a digital clock and does it matter if it’s am or pm? [img]/content/btubb/images/%%GRAEMLIN_URL%%/laugh.gif[/img]

                    It can be reversed.

                    I had to to a service job somewhere they changed the yoke assy and the machine would not spot pins.

                    The keyway is not centered.

                      Kingram.....why do you not ger rid of the troublesome respot cell plastic inserts when you rebuild a table?......when they break the roll pin is a problem.

                        <font size="2" face="Verdana, Helvetica, sans-serif">King, what is your setup? Do you not run plastic inserts at all or do you have new fingers that have the snap on inserts?

                        I have the same setup as Kingram. They rarely break, and if they do its pretty quick to replace the insert in machine.

                          I use the snap-ins as well. This way, you don't have an exposed roll pin binding up your cells if it falls out or breaks.

                              I have both styles, and I am changing to the 82/90 snap in style slowly.

                              I do agree that the roll pin creates problems and I usually just remove it.
