So, I bought a used Albrecht chuck off ebay and on examination it felt a little "gritchy". I checked the runout and got .005" which I think is too much so it's time to disassemble and give it a good cleaning.
The insides were filled with gunk and grease, no wonder it felt crappy. There was also some minor corrosion which cleaned up with solvent and a red scotchbrite pad. Two of the three jaws were slightly mashed on the contact edge leaving a slight flat spot about half way up the jaw, not super bad but not perfect either. The big find when the grease was soaked off was that two of the ball bearings were either broke in half or just worn that way. I think there should be 24 balls in this chuck (1/2") and what I have is 22 balls that still look round and 2 that look like they were cut in half.
So, where does everyone get replacement parts for the Albrecht chuck? If the balls were good I would have put it back together and tried it out with the jaws as is. If the runout was still .005" then I would consider changing the jaws out but since I need at least 2 balls anyway I am leaning toward just replacing the jaws now.
