    You can buy the gear puller at Harbor Freight. I don't know if they have sewing machine pulleys. Clutch motors have a keyed 3/4 inch shaft diameter and use a 3/8" to 7/16" belt pulley. Most machines in tool stores use 1/2" belt pulleys. If you put a 1/2" belt pulley on a clutch motor, the 3/8" or 7/16" v-belt will drop deep into the grooves and may flip sideways. I recommend buying a sewing machine pulley from an industrial sewing machine dealer.

    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

    Help! I bought a Tacsew T8700 High Speed Straight Stitch with a Tacsew Clutch Motor Model: RM1878-1H (don't know what the RMP is) when I was doing model home decorating (window treatments, etc). I could never use it as the dang thing takes off like lightning and usually breaks the top thread! The local business I bought it all from said none of it came with a user/maintenace manual. Not surprised as that is the business they are in. I've been reading here about speed reducers. Can anyone help me tame this wild beast!??

    BTW, I've been sewing for over 40 years and am very good with machines and electronics....the owner came to my house and charged me $90.00 to tell me that I shouldn't have bought an industrial sewing machine if I didn't know how to use one!!!! I bought it from him....some customer service this guy!

    Also, I'd really like to trade it for a walking foot head that will sew leather, fine to thick.

    Thanks and good wishes to all who read this,

    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......

    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
