  1. I bought my pulley from an industrial supply house named Mcmaster Carr ($3.50). The small pulley available is the correct pulley for the L3 belt that was used on my Pfaff1245. The belt cost around $5 at a supply house called Motion Industries. The original belt was 48 inches and the new belt is 44 inches. Again, the belt series is an L3 width. This is standard for 3/4 inch ID pulleys, one would have to go out of the way to obtain a 13/4 inch OD pulley with a 3/4 inch ID that uses a 1/2 inch belt. So how does it sew? I find that I am better able to control the materials I feed into my machine, and the seam is much straighter as a result. I plan to convert my Juki dual needle as well, it sews far too fast, uses the same 3/4 inch shaft on the output of the clutched motor, I have an extrapulley for my Juki
  2. you can change the lower pulley to the smallest possible size for about $10 including the new smaller belt. I just did this on a Pfaff with the same clutch drive. At full speed I can manage quite nicely with full power at the needle. This mod will require a puller, easily found at Harbor Freight. Or pay for an electronic controller......
  3. cont. leather, I have some of the same sewing needs, which brought me to this forum

  4. I am sewing sails for smaller sailboats, and making covers for same. I use a Bernina zig zag, a Juki 2 needle and a Pfaff 1245 for my small business. Although I do not work

  5. I have a Pfaff 1245 Medium weight sewing machine. It was capable of sewing much faster than I can accurately feed materials. I replaced the clutch pulley with a much smaller pulley from www.mcmastercarr.com . I can now easily feed heavy materials into my machine, at full clutched power. Removal of the original pulley required a 2 jaw puller, and I cut down the old vee belt and took that in as a measurement for the new, smaller vee belt necessary after this conversion. Apparently, even chinese clutch drive motors have a 3/4 inch output shaft, easily matched at the above source. Good luck John S
