Question about Bernina Bernette 75
Hey Rick...I am trying to replace the cam stack gear in a bernina 730...I have taken out the gear and kept the cams in position with each other...but now I dont know the overall location of the cam stack relative to the rest of the machine...I fear the needle will be moving when its in the material....if you could help...that would be great...thanks..Ron
It does not matter where the position of the camstack is when you put it in, it should not affect any other part of the machine.

You only need to worry about the handwheel and the long shaft turning while the camstack is out. If the shaft the worm gear below the camstack were to turn at all while the camstack gear is out it will throw the needle pendulum swing off. Thus requiring adjustment tweeks of the worm gear after the new camstack is back in. Loosen screw(s) on worm gear, move slightly and check pendulum swing of needle on wide zigzag. If its not right keep tweeking the worm gear until it looks good. A peice of paper under the presserfoot will show tears if it is off.
