v belt Pfaff 145 servo

[ben27]

Hi all! I just registered on the forum. I have a Pfaff 145 and just bought a servo motor. The v belt that I had is now too long. it is an optibelt 10x1060. I tried measuring with a string and ended up with 97-99 cm inner diameter. Is there a way to keep using this belt? And if not, what belt do you recommend? Any people with experience with this clutch to servo swap? Thanks a lot!

I would go to your local hardware / auto store and see what they have. If the new one is to short / long exchange it for another.

I moved your post to leather sewing machines

I've been ordering belts from amazon. Here is an example: https://www.amazon.com/uxcell-Classic-Wrapped-Outside-Circumference/dp/B0DR767RWV

You can also get them in white: https://www.amazon.com/dp/B0BK1FQHRR

Other options include adding a wooden block between the table and the motor (a spacer) so you can use the longer belt. This may require longer bolts though. Or 3D printing a larger machine pulley, which has the added benefit of slowing it down and increasing torque.

Lots of folks have swapped clutch motors to servo motors. Any particular questions you have about the swap?
