OK folks, here is the "scoop" on how to remove the ratchet assembly on a Craftsman 1/2 inch ratchet 43773 EE 7.
After many hours of researching the web, and reading old posts on different tool sites, and even manuals, ,,,and then trying them all,,,,HERE IS HOW YOU DO IT!!!
And it is SO easy,,,after you learn how!!!!
Lay the ratchet on a hard surface, like a workbench, with the selector UP.
Then get a round end 1/2" dia.,,like a punch handle end.
Place the end on the center button and push!
Not hard, just push.
The button will stay in and a "CLICK" will be heard.
You can now easily pull out the whole ratchet assembly,,, look at it, lubricate it with your own brand of lubricant/grease.
Then place it back in the handle after you spread lube on the exposed gear teeth in the handle.
Then holding the ratchet assembly in the handle,,,turn it over, holding it all together with your fingers,, and push the small round steel pin sticking out of the front plate.
"CLICK",,,you will hear it! now it is licked in place!
THAT'S IT!!!
It's locked in and absolutely ready to ratchet.
Even a big fingered Texas dufus like me,, could do it!
