Nothing is worse than having a technician arrive at your business and after a brief look he tells you we must order parts. The repair is delayed, additional expenses of return service, and the lost use of the machine gets expensive. I have created a list of the most common parts and suggested things that may need to be replaced on a machine. I call it an Emergency Repair Kit. I suggest you order one for each head, but you will probably not need everything in a set for each head. This list of parts is a suggested list. They cover the most common parts that may need replacing when you have a service on the machine. This is also a list of a good set of spare parts to have on hand. You know your machine so if you don’t have issues with it trimming you may not need to order the knife sets. If you haven’t replaced the rotary hooks since you bought the machine you may want to order all four. If you don’t need a new set of needles you don’t need to order them. Consult your parts supplier and parts manual for the correct parts for your machine. |

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.
How can you tell if you need a reciprocator?
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.

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.

Rotary Hook
Rotary hooks rotate twice every time the needle comes down, so if you run your machine at 700 stitches per minute the hook spins at 1400 stitches per minute (SPM). The interior of the Hook has a rail that slides in a raceway and holds the hook together. There are no bearings, so the rail and raceway are metal on metal. This is the only point on the machine that most manufactures recommend you lubricate every four hours of use.
Rotary hooks may need to be replaced at around 3 to 5 years, depending on use and maintenance of the machine.
