Terry,
Sorry to hear of your troubles. Sounds like you have a few issues to
deal with.
---------------------
At first I was going to give you a detailed description of how the
entire system is supposed to work but I don't know how technical you are and
you may already know how this system works at this point. So I will skip to
the chase and give you some common reasons why one hears clicking of the
gears.
Depending on how much use your machine has had and how clean it is can
make a difference here. I've seen thread tangled in and around the gears
which prevent them from turning freely when necessary. If you lift up the
red roller arm and then push on the little red button on the back of the
needle case, you should be able to turn the white gear (and corresponding
thread feed roller) without any resistance. When you let go of this red
button, VERIFY that the teeth of this white gear are in line with the others
across the back of the needle case. IF YOU DON'T VERIFY THIS ALIGNMENT, YOU
MIGHT JUST CAUSE DAMAGE TO MORE GEARS.
I check #'s 1 - 8 when on needle 16 and then color change over to needle
1 and then check #'s 9 - 16.
Now as for the drive gear, I've seen several times already where someone
has lubricated an area they were not supposed to which has caused problems
in this area. Just behind the white thread feed drive gear is the thread
feed drive motor (right side of machine). On the shaft of the motor is a
two part gear piece that is silver in color. The first gear part, which is
closest to the motor, comes in contact with the white drive gear. Then on
the end of the motor's shaft (left side of machine) is another gear looking
part that spins inside of an upside down sensor. This is the sensor that
determines the home position for the drive motor and drive gear. Because
the end of the motor's shaft looks very much like a gear, I've seen where
folks have placed a great deal of grease there only to clog the sensor and
render it not as functional as it was designed. Even the smallest amount of
grease can cause troubles here. Make sure it's clean and free from any
foreign debris.
You also want to make sure you don't have any thread tangled around the
thread feed drive gear shaft.
Do you ever use spray adhesive around the machine?
If all of these troubles started when you installed the new thread feed
rollers, there's a chance that your new rollers are the reason that the
system is not spinning freely. Were you sure to put a little polymer grease
on the the hubs of the rollers? Did the new rollers slide into there slots
without any hang-ups? Did you clean any and all debris or residue from
where the new rollers are to be installed? Figure this, if any part of the
roller system is not allowed to spin as it's supposed to, then the gear(s)
might find itself in a position between two teeth which would then result in
neighboring gear teeth hitting each other during color changes.
If the teeth collide with each other, then that interrupts the smooth
flow of the color change motor which could end up giving you the "color
change index error."
As for the thread coming out from underneath the rollers, this could be that
the red rollers were not greased correctly. Do not put the grease on the
inner portion of the hub on the black arm. You put the polymer grease on
the outside of the HUB (axle) that the roller slides onto. A thin coating
is all that's necessary. Usually you apply the polymer grease to the top
side of the hub but it needs to get all the way around to the bottom side of
the hub because that is where all the pressure is on the red roller.
You can tell by looking and touching (with dry fingers) if your rollers
need to be washed or not. Sounds like you might be washing a little too
much. You only need to wash them because you may have put too much grease
on the roller's hubs and some got onto the rubber surface.
I have a few questions for you. How long have you had your machine and have
you had any maintenance training other than manuals and software
instruction?
Thanks,

Subject: [amayausers] gears not lining up
I have also been having a devil of a time with my Amaya and the gears not
lining up. This all started after I changed to the new yellow feed rollers
and red pinch rollers. Shortly after the change, the Amaya started making
the loud snapping noises as the needle bar changed needles, she also gave me
an error message that there was a color change index error. The needle bar
would not line up behind the needle, etc etc etc. After a day or two of
messing around with this I phoned Chris in Calgary. He had me push in the
little red button that is above the thread feed gear on the back of the
needle case. This little red button allows the gear to free wheel.
Wweeeelllll let me tell you the needles that were being the biggest pains in
the A--, those thread feed gears were wobbling around like a drunk in a high
wind. They had broken off around the hub just like Ron Springer(I think it
was Ron) said in a previous post.
Consequently I ended up with a whole new feeder gear assembly. Hubby and
I changed it over and in the process discovered that the gear that is
driven by the motor(this gear is the one that turns the feeder gears) was
also broken around the hub, and also wobbled like it had its fair share of
liquid refreshments.
We replaced this gear as well. Scavenged another gear off the old gear
drive assembly, and off we went. It is a bugger to adjust and to line up
the gears again. We got through Christmas, and I am starting to get the
snapping sound again. Every time I start the Amaya up I go to maintenance,
steppers and "home" the needles I am going to use, and I have to do this
every time I want to use the machine. The new rollers also love to "spit"
the thread out of the grooves and cause birds nest's. I was told that this
is because the rollers are "dirty" so I take thiese out, wash them, put them
back in and then go again for another 12000 stitches and then wash again.
So my question to you on the list that have had problems with the snapping
noise etc, did you notice it started ofter changing the rollers?
