Drill chuck repair

[Brento]

How does one take apart a keyless and a keyed drill chuck. Id like to clean them both up and then repair if need be. Also how do you remove the arbor on them?

Hi this may not be the chuck you have but it will probably give you some pointers

Generally to remove the arbor you use two thin opposing wedges to eject the taper

Most of the chucks are pressed together and to disassemble them, you need to press them apart. Just do a search with the chuck brand and "repair" or "disassembly" in the search bar and you will get millions of pages of somewhat useful info.

As for removing an arbor, wedges are the preferred method, especially if you want to salvage the arbor. However, sometimes there isn't a ledge for the wedges to push against, so other options are to drill a hole in the front of the chuck and use that to drive the arbor out (I hate this method), or you can just sacrifice the arbor and cut it off about 3/4" from the chuck, then drill and tap the remaining stub, then use a pipe coupler, some washers and a bolt to extract the remaining stub.

I think abom79 may have had a youtube video on taking apart the Albrecht keyless drill chucks, don't have a link handy though.

EDIT: No it was oxtoolco, here:
