Milwaukee magnum hole shooter chuck

Thanks B and V.
I liked the jacobs site: "repairing a keyed chuck", easier and cheaper than repairing a keyed car

I looked at it squarely in the jaw and said "Where do you come off Chuck?"

Actually that (joke) probably only works in person. Mine has a reverse threaded allen cap screw which holds the right threaded chuck to the arbor. After removing the screw the manual says stick the key or drift punch into one of the key holes and give it a sharp rap.

When that didn't work, I got out the "seal club" (BFH) and whaled the piss out of it. I suspect it was at this point where things went awry inside the chuck.

This whole project began when the thing started sounding like it was missing half of its teeth in the gears. I opened it up to see what the noise was all about and couldn't really see much wrong.

I pushed some of the grease back onto the gears and put it back together. It sounds much better at least.

I'll play chuck doc tomorrow and let you know how it works out.

I'm suspecting that closing the chuck jaws first maybe would have helped stabilize the internal bits.
