Pulley on the machine or on the motor?

Gentlemen, I also have a Problem with my Singer 211G155.... I would like to slow it down a bit. I was wanting to replace the 4in. pully with a 2in. pully....Problem, I don't have a clue where to find a 2" pully. Could any of you guide me to a place that I could acquire one.   Thanks a lot....

I have a similar machine in my leather and sewing shop. The machine pulley is a fixed size. You probably want to replace the motor pulley with a 2 inch pulley. You need to measure the diameter of the shaft, then eBay it. Or, order from one of our supporting dealers, like @CowboyBob. I think that clutch motors have a 3/4 inch shaft, while most servo motors are 15mm diameter. Once you know the diameter, order the small pulley and also get a new v-belt that is that much shorter. The old belt will be too long and the motor may not have enough adjustment to compensate. V-belts have their length stamped somewhere on the outside. A typical -belt for a 4 inch motor to 4 inch machine pulley like your setup might be 44 inches. But, it could be less. The new belt would be 2 inches shorter if you get a 2 inch motor pulley.
