Thank you brother for making this video it was very helpful everyone else takes her truck off and replaces it you have shown me how to fix nine from making the worst noise ever you are appreciated sir
Rolingmetal No problem :). Mine just go up to 13mm so maybe that’s why it used 3,16 (that’s what I measured but I think the correct official size might be 3,175mm). I tried with 4mm balls but they didn’t fit at all.
Thanks for this video! I have the exact same chuck that I need to take apart. I doesn't run true on my drill press. The arbor it sits on does run true... Very helpful to see how it is supposed to come apart before applying force in the wrong place. Gotta love YT for being able to find info like this! If I find ball bearings inside my chuck, I'll let you know the measurements.
Yes it did! It took me several hours to get the chuck to open. In the end I had to borrow a bigger pipe wrench than I have to get the job done. Maybe I can help you out too: The ball bearing inside consists of 28 balls of 3.2mm diameter. They sit in the groove of the inside cylinder and ride on the little ring that sits inside the main body. Hope you can find some suitable bearing balls for your chuck!
I have a Chinese chuck in which the ball bearings are 4mm with 23 total. I notice that most leave about a bearing width in the ring of ball bearings rather than have them shoulder to shoulder. Mine is quite a bit different than yours however. No two race surfaces just a ring of bearings that the center holds in place against the cone when you drop it in.
is missing an outer ring that clamp on the arbor side and take that movement... thanks for video ... I have one new witch is in perfect condition and on first use that top sleeve get loose, but I have not disassemble it i will put some thread locker to not get so easy with the hand.
This chuck appears to be the same design as an Albrecht. According to a quick internet search they take (25) 4mm ball bearings. 5/32" diameter would also work since they're only .001" difference in diameter.
@@Rolingmetal I just rebuilt my albreght 1-13 looks very similar in size, design is same except the bearing there is no separate race, the body and shank are the races. The rear knurl ring is tightened to keep the chuck from sliding apprt.
I have a metabo futuro running offcenter in my drill Press! Also mine has a sort of collar on the top, where the morse taper drive in, clamping on the ground bar yours has exposed
Rolingmetal toghether with the bearings It May solve your longitudinal play and wobbling: the bearings stop the end thrust and the collar, put in contact with the Chuck and tightened , keep all the parts tight toghether (maybe) I'm going to disassemble mine, i'll let you know what exactly It does
This second-hand keyless drill chuck is severely worn, has lost its accuracy, and is generally of no use value. But your craftsmanship is great and you dismantle it very carefully. I give you a thumbs up.
Hello, This is a great video, I took my 5/8” keyless chuck apart because it was making a grinding noise when I turned it in either direction. Upon opening it I noticed right away that no parts were deburred. So I deburr and clean. It seemed I was short on bearings so I measured the shiny mark where the bearings ride “The race” and it measures 34mm x pi 106.814,divided by bearing diameter 4mm = 26.703, I have 24 bearings and I think I should have 26. The 26 leaves .007 mm for grease and movement. If I am wrong on the number of bearings could somebody please let me know, there is no possibility that I lost or misplaced bearings. Again great video and I’m sure that it helped more people than you realize, it helped me. Thank You.
Very interesting. I have seen videos taking apart Jacobs and Albrecht chucks. This is completely different design. Some flea market gambles pay off, now and again they do not. For you it is not so much the money but needing a working chuck for the lathe headstock. Bummer about the ball bearings. Jacobs "standard duty" chucks do not use ball bearings. The "Super Duty" chucks have ball bearings and a hefty price.
The fact that the ball bearings are missing doesn't bode well. But it will probably still be usable on the wood lathe once the ball bearings have been replaced. I'm currently working on plan B to get a drill chuck for the headstock.
Are you still looking for the ball bearing size? I just took mine apart and cleaning today so will let you know if your are interested- I found all the ball bearing that went over the floor
ouch, ball bearings flying over the floor happened to me before too. BTW markhiggins have you become a flat earther yet? If not I suggest watch a 13 part series called _What on earth happened_ by Ewaranon to learn that the earth is not a globe. I got it in my about tab.
You probably know this, but I will post this anyway. If you get a bike, maybe for free, there are balls in the crank, the steering, and in the axles and probably in the pedals. one size may work for you. I would use a size slightly narrower than that spacer shown. Then use grease to hold the balls when assembling.
you can order different sizes of ball bearings from china on ebay,i have done this myself.dirt cheap.i would measure the bearing raise and take away clearance measurement and start there.order 3,4,5,6,mm ball bearings.have you got anything with bearing that you can get the balls out.
Thank you brother for making this video it was very helpful everyone else takes her truck off and replaces it you have shown me how to fix nine from making the worst noise ever you are appreciated sir
"ZU" = close, "AUF" = open ;)
That is very similar to mine. The top knurled ring is a slip press fit once removed the center (holds the adapter) comes right out.
Thanks for the video, I just was fixing one of these myself :). The ball bearings in my one was 3,16mm.
Thanks for the feed back. Does yours also go up to 16mm (5/8)?

Thanks for counting and measuring the ball bearings.
And, did you succeed in improving the runout?

You are right, I looks a lot like the Albrecht design. And those come in different sizes, perhaps using different sized balls.

I've seen those collars on pictures and I'm wondering what purpose the serve. The look rather redundant to me.

Get it yet? I just took apart a 1/2" Rohm Supra SK key-less chuck.

Auf=loosen. Zu=tighten.
You might need to press the röhm chuck like the Jacobs chucks.
Thanks for the German lesson :)
I have the same chuck, not the best in run-out. It needs 29 balls 1/8" (3,14mm). And the clamp ring on yours is missing as far I can see.
Thanks for the information.

The rohm cap is pressed fit
I used a bearing puller in my press.
On the Röhm chuck, if memory serves me well, carefully try to knock the upper knurled part, it is a cap, upwards, the rest is easy.
The knurled top screws off but only gives you access to the jaws as far as I can tell. Then I got lost :)
I meant the other knurled part, the one of above the letters. It is a press fit cap/ring. You can tap it off lengthwise.
In my Metabo futuro was 3mm ball.
5.21 Yes
what pipe wrench are you using? need one greatly. thanks
I only know it as a "sokketange" and that's Frisian for pipe wrench.
I have the same wrench made by Bahco which I bought in Denmark about 30+ years ago, a really great tool.
its a "swedish" pipe wrench

There are more bicycles in the Netherlands then there are people. Me. I got about 10 :)
My chuck have 3,95mm ball bearings
you can order different sizes of ball bearings from china on ebay,i have done this myself.dirt cheap.i would measure the bearing raise and take away clearance measurement and start there.order 3,4,5,6,mm ball bearings.have you got anything with bearing that you can get the balls out.
I'll check the local bicycle store first before I go order lots of ball bearings I will probably never use.
