Drill Chuck stuck

[seabeerob213]

Trying to remove a broken Chuck there's a couple bearings blown out in the chuck, Chuck sticks at random spot. While opening and closing. Trip g to remove it cause I have a new having Chuck that's been rolling around my toolbox since 2008. The bolt came out easy. The Chuck won't unthread. Tried the hammer with an Allen wrench, then an Allen socet on the breaker bar, also with a hammer, the a half inch impact on the impact at 100 psi. No luck. It's a Bosch drill, half inch Chuck, 18 v. Rohm Chuck on it now. Had the front half off the chuck to clean and lube when I found the meassed up bearings.

I’m guessing you’ve tried both directions with the hammer technique?

Yes, after all failed, o stuck a soldering iron in the chuck with they tip down in the Colt hole, let it get the whole chuck hot, pulled it out, and sprayed kroil in there, and it's been sitting a couple hours now.

Make sure its in low gear.
Use a 3/8 or 7/16 hex key if you have one.
Try clamping the hex key in a vise to minimize twisting and turn the drill by hand.

I usually grab my biggest 1/2" drive torx socket (a T60) in the chick, and then hit it with my impact wrench. It has never failed me yet, when the allen key method has failed me many times.

You have the keeper bolt out, right?

Couple an impact to the chuck; it'll come off.

Bolt was easy, but this cork stuffer is really in there.

You mean this one that's been tried about 10 times on fell send with a full tank at 125 behind it?

I do, but you need a more powerful impact.

A similar Rohm chuck gave me grief one day, an Milwaukee M-18 fuel whaling on high wouldn't budge it, what really helped was using a pencil butane torch inside which heats up bolt, expands & cracks that seal. First time after using heat, the impact got it.

He has the bolt out. It would be useful to know if it was left or right hand threads.

Is the drill spinning with the impact? If not, you need a more powerful impact. Maybe someone used Locktite. I took a chuck off of a Black & Decker #361 slow speed drill last week. It has been on there since the early 1980's. I used the biggest allen socket that would fit and my old Snap-On CT3850 cordless impact and it came off after a couple of hits.

There could be a thread locking compound in there. Heat will release it.

The picture above shows the keeper bolt has left hand threads. The chuck is threaded on right handed.

↑^Yup for sure. To be clear I'm suggesting heat after you've removed the retaining screw for the larger bolt on the drill that the chuck screws onto. You need to heat it up through the inside of the opened chuck. Made a big difference. Yeah & thread locker sux.

Not talking about the retaining screw, whaling an M18-Fuel impact on that would strip/sheer that little screw in seconds. The chuck screws onto a 10mm or 12m bolt on the drill.

 

[seabeerob213]

I'll try heat again after work. No chance at getting a bigger impact. I only have this cause I borrowed it to work on my car. reatained screw is out and is reverse thread. The drill did not spin with the impact on it.

Try briefly, intermittently blipping the drill in the opposite direction of the impact, too. Obviously prolonged trigger-on risks burning up the drill but one second at a time won't hurt it

 

[seabeerob213]

Still no luck. Might take it to the diy auto shop on base and hit it with the big impact this weekend when I throw the car on the lift for an oil change.

Threaded chucks are always rt handed to tighten when drilling and the screw is left handed so the chuck does not come off when the drill is used in reverse. I have seen tapered spindles used on a hand drill. They would be bidirectional.
