Distance Between MotorsHorizontal line above in Red
This is the measured distance from where the chain leaves the motor on the left to where the chain leaves the motor on the right. This was measured from the 8-o'clock position of the left sprocket to the 4-o'clock position on the right sprocket - at the center of the chain connecting pin.

This is the distance perpendicular and down from a line that would exist between the two chain-exit sprocket positions in parameter to the top edge of the work surface.
