Need Help with new Servo Motor install and Needle Positioner!

[Lorddrick]

I also have the CSM3000 and mine also hammers out five stitches the first time I press the pedal after startup.  Doesn't make sense and I would like it to not do it.  Other machines I have (with different motors) do not do this.  

I'm looking for a speed reducing gearbox.  Looking only and feel like I should be able to find one that bolts to the input shaft side and then I move the entire table mount assembly left to allow the new output shaft on the gearbox to align with the machine pulley through the table.  

I'm having trouble finding any official documentation regarding the mount size or dimensions.  The Plastic guard holes seem to be 45mm or so.  The metal cover mounts are 65mm spacing.  Haven't disassembled it as I'm actively using it on the machine.  

Anyone have any idea what NEMA mount it official is, and what straight female to male gear reducers might fit?  

Thanks, everyone.
