Default Toyota ESP 9000 locks up

Hi everyone, I'm hoping someone can help me.
I bought a used Toyota 9000 and I'm having a hard time with it.
While its going through color changes to the next needle I've noticed that the take up lever is not locking back up always. It will either stay partially down or fall all the way down. So if my machine needs to go past that needle through a color change the machine hits the cam roller in the back locking it up and the machine shakes like crazy . I then hit the E stop button and shut it down .
I push the take up lever back up, turn on the machine and reposition it on the right needle and continue. It happens on different needles and not all of the time.
I've also noticed this 9000 does not have a take up lever guide in the back like some other ones I've seen.
Anyone have any ideas on how I can fix this or has ever dealt with a problem like this?
Any advice would be great
Thanks
Jim

Hey Jim,

The 9000's takeup lever guide is short. It only has 4 or five takeup levers touching it at any given time. The guides are locked in place by a latch (not sure of the official name) that is located right above the nylon gear. You can see the latches from the back.

From your description it looks like latches are not engaging fully or they are slipping.



Things to look at?

- The latches or the gears on the takeup levers may be worn or broken. Check for wear and replace if needed. I have never had to do this on a machine but it is possible. I would look for something causing the wear.

- The takeup levers ride on a steel rod. All of them are stacked on that rod like a Shish Kabob. On each end of that rod is a sleeve that spaces the levers and keeps them tight. You may want to check those to see if they are tight. the levers should not have any play left and right.

- Some times the springs that activates the lock becomes disconnected, weak or bent. Doesn't happen very often and don't know why it would affect more than one or two of the levers.

- There is a roller bearing attached to the color change assembly that disengages the takeup levers and allows them to move up and down. It may not be letting the latches fully engage. You may be able to adjust that?
