Diving in.

Careful, that is critical IIRC. You must put that back close to where it is if you want it to run properly.

Almost all I have taken out have been 15-15.5 turns in from the first thread catch.

I believe shaft seal is only seal behind that and it can be taken out from the exterior. Should I forgo totally break down of the pump?

I thought the teardown was necessitated by the need to clean up the spill collar?  Or was it Gov weights not freed up?  To many threads to remember.

Note position of shaft on the nut.  Only a few threads showing?  Like the post from 8 V says.  Count the turns the you make to remove it and put it back to that.

Im going to try and get it out I want to tear it down but the bugger is resisting

Nothing moves in any direction. This is iritating.

I usually break them free with just an allen key alone. Some are reverse threads.

When it get loose, I back it out just enough to get to the seal, so the gov bits don't drop into the case.

I made a tool for the lock collar by grinding a socket to have two lugs on the edge.

I might have to join you with that diy tool. I was thinking about doing the but now that I know it works I will be doing it.

Anybody bought a rebuild kit from grumpy on ebay?
