    Hi Russell,

    Have you discovered just what the problem is? To start having problems
just because the rollers were changed out would be unusual. When replacing
the entire kit, did that include replacing the red pinch rollers AND the
black plastic covers? Just have to be sure on this......the holes in the new
plastic covers are larger than the older style and the pinch rollers are
knurled on the surface. I need to ask some questions......it is very
difficult to diagnose a thread break problem without going through a process
of elimination not knowing what you have already done. Some of these
questions may seem unnecessary but have to be asked to gain a data base of
info on my end.

    I have not witnessed the overall increase in MT as is described in the
instructions..only on some things....still need more experience with this.

    Is the thread sticking to and being sucked around the new rollers? This
definitely causes a "pop" when this happens and the thread breaks.

    Were the rollers squeaky clean with no oil or grease on the surfaces to
pick up the thread?

    IS "force download" turned on? If not, turn it on. Your design may have
become corrupted in the RSA and CSA download to the Amaya. We must eliminate
the design as a potential "cause" regardless of how many times it has sewn
out perfectly in the past. What is the design? Is lettering involved? Short
stitches off or on? How big is the design......small? Jacket back?

    Is your presser foot set correctly?

    Have you tried to sew the "Ampass" test design? When you run this
design, use two pieces of medium to heavy backing, MT of 3, 1200 stitches
per minute and your presser foot properly set.

     Are your needles set straight ahead or 5 degrees to the right....never
to the left?

    Is the thread breaking happening on all needles? Or certain colors of
thread? New thread, old thread?

    How about needle depth...the newest speck is to have 3/8" plus or minus
1/8" of the eye of the needle showing in the bobbin case area at bottom
center position.

    Poly or rayon thread?

    Did you grease the center bearing post of the red pinch rollers? Did you
grease the center brass bearing surfaces on the new rollers?

    How tight is your bobbin tension set?

    What needles are you using? Size, brand, titanium, standard?

    Have you thoroughly cleaned out the bobbin case area?

    Have you been using sticky spray or were you using sticky back backing
with fast frames?

    What backing and what material are we talking about?

    Hooping tight/taut?

    Thread spindles at the proper height?

    Humidity. Has it changed or about the same? Is the thread untwisting on
the trimmed ends? How about the break, is the end of the thread badly
frayed, untwisted, or is it a clean break?

    Have you, or do you know how to do a "Thread feed 200" check to see if
the thread is being fed at the correct amount by the computer?

    Is your needle plate centered? Have you carefully checked the hole in
the needle plate for needle strikes and/or burrs?

    Have you checked the face of the retaining support finger for the hook
to see if there is a scratch/gouge/burr on it?

    Have you looked (magnifying glass) at the face/surface of the hook for
any scratches, burrs, damage from any broken needle etc?

    This is just a start of the questions that run through my mind when
someone says "thread break." All things being equal, and the only thing to
have changed is roller replacement, and given the fact that you did not
mention any problems before this replacement, one must first go back to the
installation of the "kit" and lubrication of the rollers. This is the place
to start and then we will go from there.

      Hi All,

          I just upgraded to the new yellow thread feed rollers and now I am
getting allot of thread breaks, the directions said to go up on the MT but
when I do the thread dances around too much in front of the name plate, the
design I was design I was working on is normally set at 4, I have tried
going all the way down to 2 and had the same problem. When the thread breaks
there is usually a popping sound, I checked the hook timing but that seems
to be ok, also new needles. Does anyone have any ideas of what might be
going on?

      Thanks in advance
