I have a Sears 149.213330 Radial Drill Press – nothing wrong with it BUT I have a tendancy to attempt to make things a little easier on ME and presently that endeavor is to put a keyless chuck on the dp.
The problem is that I can’t figure out how to remove the existing chuck to put a keyless chuck on it.
The chuck on the dp is an RJ 3 – 16L – there is not a screw inside the jaws but there is what appears to be a collar that requires a spanner wrench to remove or loosen to get the chuck off.
Problem #1 – I don’t know which way to turn the collar
Problem # 2 – I attempted to turn it both ways and all I got done was to make a tight spot at the very beginning of the shaft that the chuck is on.
problem # 3 – I have looked and looked on the net for an owners manual and it appears that one does not exist.
Any help would be greatly appreciated – oh btw, I have a beer fridge in the garage that is fully stocked should you happen to drive by and stop.

Here is the manual for a 149.213340 which should basically be the same:
http://powertool.manualsonline.com/manuals/mfg/sears/149213340.html

The chuck is on a taper, so you just need to knock it off. I would not put a keyless chuck on though… there is a reason most don’t come with one – you can’t tighten them enough and will wind up spinning bits, particularly large ones and when doing tough material like very hard wood and metal.

Cheers,
Brad

Dick, check this out on YouTube – It give some suggestions on how to get more info on the Craftsman DP chuck. Hope it helps. BTW, I’ve used the Red Cedar, but I haven’t been into the shop for the last 10 days or so, been fighting a lower leg infection. On the mend now, hopefully I can get back in next week.

Parts listing shows the chuck, and it looks like a standard taper fit…

Don’t see any thing else that would secure it to the taper shaft in the exploded parts diagram… maybe yours has been modified from original if it’s different than what is shown.

Cheers,
Brad

PS: The parts diagram in the manual I linked to looks almost identical to the one on the sears site for your model number, with the only exception I see being the table (one is round, other isn’t). It does show a collar, but doesn’t indicate where it goes and is not shown as part of the full quill assembly (#37 in the diagram). Based on where you say it is, it is most likely just a cover to protect the lower quill bearing. A picture would help :)

Dick, I too have a Craftsman dp, not like your radial, but similar in construction. There is no quill to remove, the chuck is a press fit onto a spindle, tapped on by mallet. No instructions as to removel, all part of a lesser expensive design & build.
Only suggestion I could make is to lightly tap if off while going all around the circumference, and I stress lightly tapping so as not to damage either component. A gear puller would be the solution only if you could get one on the chuck, which you can’t.

I did a quick search for that chuck number (RJ3-16L) and it indeed has a Jacobs taper #3 mount, so it is just an interference fit and should pop off with some light taps, or you might need to get a couple wedges if it’s really stubborn. There are other methods (such as using a homemade slide puller) that a quick google search will turn up for you as well. It’s also used on quite a few other model presses (Rikon, Jet, etc…), but I doubt any of them show how to remove it either – just how to install it.

Cheers,
Brad

OK guys – it’s off ( I found my stupid switch and turned it off, only tempory of course )
good ol’ hammer and block of wood. Now my dilemma, The keyless I selected from my stash won’t fit because the shaft size is wrong. Oh well, maybe I’ll put one of the better keyed Jacobs chucks on. I have a couple that run smoother than the one I took off. Not that it’ll make a hill of beans difference but now that I’ve put you guys thru all this I have to do something.
Well, it’s 5pm here and I think I’ll locate that beer fridge and make a selection (or 2)

Thanks guys
