First time disassembling an Albrecht chuck

[Z2V]

You can also use two dowel pins and a vise to get certain arbors out, MT5's and maybe 4's.

Excellent idea. Two #29 drill bits worked just fine on a JT33.
Yeah, I know this is an old thread but it worked.
Thanks

An Albrecht keyless chuck relies on the threaded spindle inside being oil-free so it can lock down on a bit and stay locked. If oil gets in there the bit will come loose and spin.

WHOA! Mind blown!

I've got 3 different eBay special Albrecht chucks that I use all the time ----

• 1/2" capacity chuck on an MT2 arbor for my lathe;
• 1/2" capacity chuck on an R8 arbor for my Bridgeport; and
• 3/8" capacity chuck on a 1/2" straight shank for smaller/sensitive stuff.

I disassembled each of them, cleaned each of them, and used Dow Molykote molybdenum grease to lubricate the spindle threads*.

Seems like I better add "Disassemble and Clean Albrecht Chucks" to my whiteboard.


*Edit: They sure do spin smoothly though!
