Re: Stuck worm drive


I remember mine also being very difficult to remove. Once I got it off, I chased the threads on the worm and ring and eventually got them to fit smoothly. I wonder if distortion of the threads from drilling the original pin hole is the cause of the binding.

Are you certain the pin is not engaging the worm as well as the lock ring?

Hi all,

First post so thanks for all the free info so far.

I've been trying to strip the apron of my 9a and can't for the life of me remove the collar holding in the worm gear, pin wasn't present and the gib is out.

It is definitely binding somewhere and I have already used as much force as I can muster with a piece of pin stock in hole as a lever, bit of heat etc.

Is it a case of breaking out the big guns and just forcing it until one of us cracks or is there a more delicate approach anyone can suggest.

The angle grinder keeps giving me this "I could have that off in 5 minutes" look :)
