PLEASE NOTE: This procedure is for the Jacobs Super Chucks only. Many other chucks need the jaws closed or open half way and a tube over the jaws to press on (do not press on the jaws). Thanks to several viewers for pointing this out!

I really like your videos primarily for two reasons. 1) you are not afraid to admit when you make a mistake. And 2) I learn a lot from you, especially from potentental errors. THANKS WINKY!!

That chuck really needed cleaning. Well done. I have taken apart regular Jacobs chucks for cleaning, but not a Superchuck. Glad you did not loose the ball bearing. The Jacobs site has a page showing the sequence of inserting jaws. It is a PDF in the Tech&Support page of the site. This page also shows the various taper details and thread mount details. Dave.

I also use kitchen foil for masking and plugging holes to keep mud daubers out of holes.

Great Video. The method of opening the chuck jaws to press directly on the chuck body might work on a superchuck, but it does not on some of the other Jacobs chucks. What happens is that it the sleeve presses the back teeth and breaks them. With the other chucks it is better to partly open the jaws and put a tube over them that presses the chuck body while clearing the jaws. Just thought I'd mention t because I learned the hard way and this is a do's and don'ts video. Thanks Winky.

I've only rebuilt one that was nit a ball bearing chuck but it was made the same as mine. Maybe it would be a good idea to open them until the jaw tips are just inside but not all the way open.

The rebuild kits for those newer style chucks are extremely expensive. Over $300. Reusing the old parts, even broken but functional, is the smart play, if you ask me.

They are very high and but still, you and buy the new for 280. Amazon has the kits for about $100... still seems high tho.

I have to warn people about buying used chucks on eBay, or anywhere else for that matter after. About 20 years ago I bought a 3/4” SuperChuck. The tips of the jaws didn’t meet when tightly closed. I bought a repair kit from McMastercarr. Those are expensive. After doing the work, I found that while a bit better, the jaws still didn’t close properly. So I took it apart again and did some measurements. It turned out that the chuck body was slightly deformed. Since they sell everything but the chuck body, there was no way to completely fix it. I ended up grinding the jaws out slightly and that took much of the problem with it. But it’s not really what it should be. Usable, but not as good as it should be. On the other hand, about two years ago I bought a 5/8” version for a nutty $69. I figured something was seriously wrong, but it was so cheap I couldn’t resist. The problem was that the key didn’t fit properly. I found that someone either tried to take it apart and couldn’t, or put it back together and didn’t get it completely pressed. After cleaning it, I pressed it back and it’s perfect. So you never know. I have a ,out of chucks. A couple of new SuperChucks, a couple used, and others. All interesting. By the way, if someone buys a used chuck that isn’t a Jacobs, be warned. They don’t come apart the same way. I’m speaking about chucks that look like a jacobs. They’re built differently. You can usually tell before you read the name. Jacobs chucks have the cuts on the housing running in the same direction as the chuck, and the others have rings in the housing.

Thank you for the interesting video. I think it was Bob Vaughan over on the old woodworking machinery site that explained about the wear on the inside of the jaws. I don't think you showed it but the "gripping strip" along each jaw can get worn to the point that each one is no longer uniform it it's shape, width, and length. thus no longer gripping uniformly along the part. It would have been interesting to see how worn your's were. keep up the good work.

Yes. Mineral spirits and then Spray Power cleaner. It's a great cleaner especially if you heat it up.

There's no numbers on the body. The gullet of the jaw is the indicator. Either way, there's only one way they index, so its a matter of trial and error. This is the "new" style, which is significantly cheaper than the older models. The sleeve can be overpressed during reassembly, resulting in improper key engagement, but is easily remedied by re-aligning the sleeve. I like petroleum jelly for a re-lube, as it's nice and light, and responds well to WD-40 if the chuck gets stiff.

You were pressing on the sleeve to get it apart, perhaps you should have pressed on the sleeve at the other end to reassemble and not press on the arbor.

But what do I know, I probably would have done the same as you.

It’s not a good idea to use grease in drill or lathe chucks, it just act like a magnet for dirt and metal chips…a light oil like 3 in one works absolutely fine and makes future maintenance much easier..

10+ years ago I bought a new ball bearing chuck. Within 6 months the jaws were junk after a few drills spun. Never in all my years have I had a Jacob's chuck do that. I was going to by a kit and found Jacob's is all Chinese. Soft metal comes with the chuck at no charge. -- Repair kits are about $75.00 from the cost of a new chuck. Any better parts out there.

For it's age it in fair shape bit the jaws are worn and it has runout. The second came on a Cannedy Otto drill press from about 1910 but I'm certain it was not original. It was in great shape and I am still using it and have been for about 5 years. This was actually my first super Chuck and I notice right off that it gripped much better than the standard Jacobs chucks. The third is I just got on ebay and it was the one in the video. Maybe its junk, time will tell. Certainly hard jaws are very important
