A Puller? Giant Socket? Please tell me more.

[ChelleRee82]

I've seen many pullers but not one quite like this. It almost looks like an adjustable wrench foe monster size bolts. The part numbers are AN 10 (yoke), AN 9 (T-handle top with 1/2"dr), AN 11 (jaws marked HEX) & AN 12 (jaws marked OCT). Check out the pictures please and share what you know.

I'm thinking adjustable socket.

As the top spindle isn't threaded I'd say it's like a pin wrench for removing threaded rings. Instead of pin holes in the rings there would be slots for your teeth to drop into and then you could use a ratchet or tommy bar to turn the wrench. It's adjustable for different widths of bearing retainer rings and there a 2 sizes of teeth for it.

Other than that I have no idea what equipment it was made for.

If the jaws are marked "OCT" I'm guessing the angles are for an 8 sided fastener?

And what is the deal with the main screw? What does it clamp down on and how? The cross adjuster screw prevents it from going through the middle. what does its tip look like? a point? a groove for another part and pulling on a (missing) piece?

I'm thinking it is a military aircraft tool. The AN may be a reference to "Army-Navy" standards for hardware and some tooling, which was prevalent during the WWII era and before, and for a while after.

+1 on Army-Navy standards. Looks like some sort of specialty tool for either landing gear or engine mounts. Not exactly sure. 95% confident it is for aircraft use.

Could it be an adjustable axle nut socket for huge axle nuts?

Found it! It's a Snap-on Axle Nut Wrench Set for big trucks, tractors, trailers & airplanes. Thanks for your thoughts.

 

[JASTECH]

Well I were a little correct.

I agree it is a adjustable axle nut wrench. One set of jaws is for 6 point nuts and the other is for 8 point nuts. Do you have any idea when it was made?
Thank you

I found it. 1955 Snap-On catalog. I have the unit with 6pt. jaws but no 8pt.
Thank You
