Reciprocator:
The reciprocator grabs the needle bar and drives it down through the cloth. It can become damaged if you hit the frame or have a Birds Nest.
The reciprocator may break immediately,
The reciprocator may be damaged and slips intermittently or
The reciprocator may not be damaged at all.
How can you tell if you need a reciprocator?
The needle may “bounce up” before it hits the cloth.
The needle may not come all the way down in the first few stitches.
You may notice skipped or missing stitches.




Note: The actual reciprocator looks similar to the image above. it cost about twenty something dollars. On many occasions something is broken on the reciprocator carrier or assembly pictured below. An assembly may cost over $100.00. I would suggest getting the carrier or assembly for your machine.
Note: Some Happy machines use a Needle Bar Driver and roller bearings instead of a Reciprocator. Consult your parts supplier and parts manual for the correct parts for your machine. See the next section.
Note: ZSK machines use a "Klinker" instead of a Reciprocator. Consult your parts supplier and parts manual for the correct parts for your machine.
