Hello, and I bet you are extremely frustrated after you discovered that the new-to-you knitting machine does not select needles properly.
I bet you watched numerous videos and thoroughly cleaned the punchcard reading mechanism, but nothing works…
I’ve been there … I disassembled my machines and discovered that this problem is pretty complex. And the service manual does not really explain well how to solve it. On top of that, most manuals available for free online are of poor quality and sometimes it is hard to see clearly enough all these small (and extremely important) details.
Below is one of the solutions to why your punch-card knitting machine does not select needles correctly.
This article applies to standard-gauge punchcard Brother knitting machines with model numbers KH820-KH894. (For bulky models, like Brother KH260, the alignment of the plastic cylinder with the clutch wheel is a bit different.)
I will not go into details on how to disassemble to the state shown in the pictures below: there are enough resources. Just one piece of advice : take detailed pictures of each step of disassembly or even record a video.
First of all, if you had to replace or remove your timing belt, make sure that the piece of the belt where the ends get together needs to be aligned with the little divot of the pulley (the manual calls it a concave part).
If you still need help, consider purchasing a lesson from my Etsy store. We’ll figure it out together!
