I don't remember how the worm gear came out. I will see if I can get mine out.
Thank you for the information. From the looks of your pictures my issues seems to be that there is a gear that slides up and down on the shaft with the pivot fork is blocking the pivot fork from 'pivoting' enough to clear the housing so it can slide off the shaft. So next time I need to find a way to seperate that sliding gear from the pivot fork.
I on your head did you also remove the worm gear that meshes with the gear that lowers the quill? If its still in place that is the only thing that I could see stopping your gear from seating properly. It looks like from the picture that it is in fact that worm that is stopping your gear from seating. Maybe try seating that gear then installing the worm gear. On Mine the gear was freed-up once I removed th3 worm gear and it would come out easily except for the pivot fork. I will know more once I can see behind that gear though.
One more question how did you seperate the pivot fork/bushing from the the gear that slides up and down with it?
Thank you again for the help it is much appreciated.
