I want to put one on my Pfaff 145 h4 so I can oil the bottom parts of the machine. I added a box style reducer to a cylinder arm machine. It has 4:1 reduction. I bought it from Toledo Industrial Sewing Machines. It required two new type 3L v-belts. I recommend locating it in a manner that lets you tilt the machine back to oil it. It can be tricky getting the right position while still clearing the oil pan and wiring. Also, adjusting the belt tension is a bit tricky. Once done, it is usually good for the life of the two belts.
