The primary arm assembly can move up and down and be swing out and back, so as to temporarily disengage the motor pulley drive to the capstan flywheel.
When the speed change knob is altered, the "corrugated" side of 119 briefly "flips" the idler wheel out of engagement with the motor pulley and capstan flywheel. At the same time, the ramp side of 119 moves the primary arm assembly up or down (as required) this is the bit I am still struggling to see how so as to align itself with the desired motor pulley speed step. When the speed change knob gets to the selected speed position, the idler wheel is once again engaged.
The metal rod connects item 119 to the record/playback speed frequency correction rotary wafer switch on the PCB.
