    1/4". Studs are cheaper than arms.

      The 5/16”!!!!! I swear by them. When I first started as a pinchaser, one of my weekly chores was to go thru every ¼” pivot stud in the house once a week & straighten them. I hated it! The 5/16” studs don’t bend & if you use the right socket lock screw, they’ll rarely come loose.
      I’ll put up with the 2 or 3 broken arms per year in exchange for alot less trouble for the bowler & myself. It's alot cheaper in the long run.

        5/16 or a 1/4? Heh i really dont know what we have but I have never seen a broken sissor at the stud. What type of play do u guys have that makes wierd things break?

          The "sissor" (scissors), as you have so termed them, will sometimes break at the yoke assy (070-007-619) if a pin gets in there & the pivot stud doesn't bend. It isn't uncommon. Maybe you haven't been a mechanic long enough to have experienced this.

            FWIW guys, we here use mostly 5/16" studs. When it comes time to change cells or anything in the area, I make sure I remove any 1/4" studs remaining.
            I still do, however, have a few 1/4" studs here and there.

            Personally, I prefer the 5/16" anyday. I have yet to experience any stress related breakages with yokes, arms, or binding. Just make sure to put 2-3 drops of oil in the casting and "twirl it around" and everything will be happy.
            5/16" I feel is even MORE IMPORTANT on the pivots for the tracks and links...not just on the cells themselves.

                hey Dutch, how do you go about straightening the stud without removing the whole finger? In my house, my fingers and tables are really getting neglected and need some work. If only there were more hours in a day. Thanks.

                  Sorry folks, I posted the wrong part # & name yesterday. The part that breaks more often with the 5/16” stud than with the ¼” stud is the lever assy P/N 070-007-618 (Although I have a notation that I wrote in my book that I should order P/N 070-002-633. I don't remember why)

                  Are you thinking of the long & short finger studs (P/N 070-007-194 & 195)?
                  The pivot studs (P/N 070-002-654 for the 1/4' & 070-007-617 for the 5/16") can just be "finessed" with a hammer, mallet, a pin or even channel locks to get them straight. Sometimes they break while trying to straighten them, sometimes they don’t.
                  In the 2 houses I work, the respot cells are probably the most neglected parts of our machines too. We have 740 RSC’s to take care of. That’s a lot of time. Somehow, we do manage to stay on top of the problems. If a lane gets 2 respot calls in the same week, we’re in there with a fine tooth comb. However, that doesn't mean their not neglected.
                  If anyone has the $$$ &amp; would like to try something different, <a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"><a href="" target="_blank"></a></a></a></a></a></a></a></a></a></a> has synthetic lubeless bushings for almost every part of the machine, including RSC's. We've been using their clutch pinion bushings for about 2 years. Their great &amp; we'll be trying more of their bushings in the near future.

                    The biggest problem with 1/4" studs is not that they break, but that they bend causing inconsistent respots sometimes knocking over the pin.
