Replaced straight shaft, and the gear head.
Removed the 2 bolts holding the gear head to shaft. On my model I had to remove the complete trimmer head, then using 2 wrench take the trimmer head adapter off the gear heD. One video showed simply putting a screwdriver in the notch behind trimmer head and unscrewing complete head. Mine of course was slightly more involved but still quite easy once I saw what needed to be done.
