  • Respot Adj.

    Ok guys i guess im probably starting to look a little dumb here, but other centers ive worked at when doing a respot cell adjustment it was a piece of cake, seeing as the machines all had the adjustable carbi-type drive link and the main link bolted straight to the 7 pin cell.I had never seen it with the fixed drive link and the adjustable link at the 7 pin, here is my problem the manual states that if you have an adjustable carbi drive link the main link is fixed to the 7 pin cell while if you have an adjustable carbi type link at the 7 pin cell the drive link is fixed, and they give you measurements to set those at, so what do i set them at when both link are the adjustable type at the 7 pin and the drive link. Again im sorry if im beginning to sound stupid its just ive never seen it with BOTH. Any help again would be greatly appreciated thanks.

    All cells are to adjusted with a small amount of play.....they should not open and be "tight" against the rubber stops.

    Adjust the #7 cell 1st....then do all the rest.

    After adjusting them...run machine through strike cycle and make sure the cells open up enough not to be in the way of the pin being spotted

    Do the 1st few cycles without pins!

      Re: Respot Adj.

      We have both styles (7-pin overhead carb, called a 2813 link, and ones that have the stringer attached directly to the #7 cell)... they adjust pretty much the same way.

      Before adjusting the cell links, check that the cells have the proper adjustment (steel block ST gauge, 2") when closed.

      #7 overhead link adjustments:

      1. Adjust 2813 linkage to 6 7/16" +- 1/32, measured from the center of the pivots.

      2. Drop other 9 carbs.

      3. Adjust the bell crank stop bolt so the load taken up by it with the #7 cell open (keeps the link from flying off the #7 cell). With the bellcrank stop bolt is against the stop, the #7 back finger should be able to move 1/8" to 1/4" away from it's stop pad.

      4. Adjust the other 9 cell carbs so they all have the 1/8" to 1/4" play in the back finger in the fully open position.

      5. See Below

      Fixed #7 adjustments:

      1. Drop all cell links (#7 fixed).

      2. Adjust the drive link (located about 1/2 way up the #7 side stringer, that connects to the drive pivot assembly) to about 3 1/16".

      3. Move the stringers so the #7 cell is fully open, then adjust the bellcrank stop bolt so that the back finger is able to move 1/8" to 1/4" away from it's stop when fully open.

      4. Adjust all cell links so that the back fingers are able to move 1/8" to 1/4" away from the stop when fully open.

      5. See Below

      All machines:

      6. Close the cells, adjust the shifter cam link stop bolt to just touch the stop, then open the cells slightly by lifting up on the link, and lengthen the stop bolt by about 4 turns, then tighten the jam nut on it to lock in place.

      7. Open the cells, run the table to spotting, stopping when the pins hit the deck (180 degrees rotation), then adjust the respot control rod (#2594, under left-front casting) so there is an .010 to .020 clearance between the cam follower bearing and the shifter cam link (roughly the thickness of a match pack cover)

      8. Crank the table to zero, then adjust the main respot rod at the front of the machine, so that the pawl clears the center point of the shifter link by 1/8" to 1/4"

      9. Test respot operation, use only 1 pin on the deck until you are sure it is operating right, then test with a full rack several times.

          Re: Respot Adj.

          thanks heaps guys, but without trying to sound like to much of an idiot im just not sure what the adjustment is meant to be if like we do have both the 7 pin cell overhead carbi link AND the
          3 1/16" adjustable carbi drive link if you adjust both links to 3 1/16" and 6 7/16" it doesnt work out ive just never seen it where you have both adjustable links on the SAME machine, sorry for asking a stupid question but it sure has me stumped.

            Re: Respot Adj.

            Sorry, I was a little vague about that... the book is too... Set the "drive" carb at 3-1/16" first, then go on with setting the #7 link. If your machines have a lot of wear &amp; tear on them like ours do, the actual measurement settings won't work... it's a good starting point, but after that, you may have to do some "juggling".

            Easy way is to set another cell (other than the #7) to operate properly, by adjusting the cell link first, and then the master if you can't get it close enough. Once you get that cell working good, drop the carb, set the #7 overhead link to operate the cell properly by adjusting the 7-link, and the master if needed, until it works right... Then proceed with adjusting the cells according to the procedure.

            This is one of those things that would take me 30 seconds to show you... I type it out for 10 mins, and it still sounds confusing...

              Just ignore the comment about the 3-1/16" adjustment. On the respot bell crank ensure there are two threads exposed. It works for me every time. No problems.

                Pin_Head,

                Try this:
                Adjust drive link to 3-1/16".
                Screw the Bell crank stop bolt in until 1 or 2 threads are exposed and tighten.
                Remove all but the #7 carb.
                Adjust #7 carb for its "cell open clearence".
                Continue normal adjustments.

                GMan,

                You should be adjusting the 2594 rod before you adjust the cam link bolt. Also 1/4" gap on the Pawl adjustment doesn't work sometimes. You should just stick with 1/8".

                  Re: Respot Adj.

                  I dunno... The above is copied direct from the AMF manual. There's so much wear in my machines that none of those adjustments hold true... if I set 'em to the book, they'd never run.

                    Re: Respot Adj.

                    GMan, If you adjust the 2594 control rod after you made the shifter cam link stop bolt adjustement you will be altering the first adjustment. Consider this. Lets say you just made the stop bolt adjustment and it has 3 or 4 turns on it to take the load off the cells when there closed. Now you go to make the control rod adjustment and need to shorten it because the bearing is binding against the link. By doing this you just messed up the stop bolt adjustment because the cells will close further(shorter control rod and longer stroke of the cam link).

                        Don't say that Pin_Head as you gain experience you'll learn some different things and as that happens someone somewhere will learn from you if ya share it. We all pick up little tips and tricks as time passes and we gain experience. And this place is the absolute best place there is IMHO as far as sharing goes
