Can we play the game "Name this Locker"?

I removed the side gear pieces. Each had springs inside pressing outwards on both sides... pushing out on the sides and also pressing inward for the two main sections. Sorry these pictures are low quality and bad lighting, but it's what I have.

Pics are pretty dark but I'll make some calls and see what I can find out for you.
The internals look nothing like a current No-Spin/Detroit.

I didn't tear apart an actual Detroit No Spin locker to compare. On this one though, I don't really understand what would make it disengage. The two springs provide constant pressure pushing the main two halves together internally. All the teeth shown on the two main side pieces don't move independently, it seems like it's just one piece and it only sits in one position properly.

My only camera is broken, so the only way I am able to take still pictures is to use the video camera, upload it to windows movie maker, and then click on stills off the video footage. Thats why the quality is so poor.

The center piece with the 4 pins has a part inside that pivots inside that causes the clutch assembly push away from the center. This allows 1 wheel to overspeed in a corner.

any ideas yet? maybe one could get a better pic with a cell phone,and a drop light?

there should be a prize for solving this!!

I'll try and get some better pictures, better than the 12-volt lighting in my motorhome. I'm working on a trade for some big block Chevy parts I have for an actual decent digital camera too.

Do all of the Detroit "No Spin" lockers use the same part number, even the Eaton ones? I lucked out and found a Detroit in the rear end of a truck I recently bought. It was 6619 51

The other actual "No Spin" I have is 66619 33

But they still both look like your typical No Spin locker, unlike this one that's still a mystery.

Found some pictures of it again whole from 3 years ago.

Okay- Here's the scoop, mystery solved. I checked with some of my old contacts that were at Dyneer (later Tractech, now Eaton) when this unit was made. My contacts have been working there for over 30 years. They gave me a description that is an exact match to your pictures.
The unit you have is a KS10 and it fits (obviously) the 14B full float axle. It is the predecessor to the model number 225S10 (part number 66627) which is used today. No parts are interchangeable with new units.

The 66619 numbers (for the newer lockers) you have are part numbers for parts and pieces of the locker, not part numbers of any finished component. If you look at the side gear, the part that splines with the axle, you should see a number 67567 stamped into it. That is the current (and used for 20+ years) part number for the 14B side gear.

I brought it back to the house and looked at it better and found the number "63041" stamped at the end of one of the "cross pins" as shown in the one picture. But sounds like you figured it out. Thank you very much for the info here! I really appreciate it and hope it wasn't too much trouble for you. Sounds like it took alot of checking though.

So, essentially, the thought that it was an early version of the Detroit "No Spin" locker was correct? And it's probably similar in strength?

Yes, it is an early version of the No-Spin. I'd use it!
