-Pump system
-Circuit wires
-Rubber pipes
-Impeller (wash) motor - placed in a determined angle and driven by one A-31 v-belt (4L3xx @ 1/2'' wide)
-Beltless spin motor - direct drive mounted on four large spiral springs (much less vibration transmitted to the frame and cabinet)
NB in order to reveal impeller motor in more detail I had to brighten up things a little bit on one of the images as shown by the lighter rectangle on the picture.
Meanwhile, if the N/S shipping line happens, one of my favorites out of these interesting arrays of twinnies is that Japanese Imperial. I don't know how I would use it , but it looks good just standing still.
