Proto Hammer Puller Problem

I was thrilled to find this Proto hammer puller, but it's missing the threaded collar that tightens the "fingers." I bought it anyway, thinking it would be a lathe project. But I am not able to find a decent photo of the missing piece. If anyone has one of these (or similar) could you please post up a photo of the missing collar? It must have a 45° chamfer around the forward face.

I have not been able to find a replacement collar sold separately at this point, but maybe one of you fellers what is smarter than I, would know how to obtain a replacement. Notice I actually need TWO of these collars if I want both operational, as pictured. (One would have a larger internal thread than the other.) I'd settle for one, as I can just change out the fingers as needed.

You can just see the missing piece in the photos below, but they're too small to make out just how they work or what their shape is.

Bolster, I'm thinking you need 4056N.

Yeah.. Call Proto/Stanley up and ask for the part number. Let us know how that works out. LOL

On the other hand ill keep a look out for one for you, I just bought a Otc model that has a similar Nut on it.

The "cone" is tapered both externally or you can flip it around and it's also tapered internally. This is so you can grip the both the OD of your work or you can flip the jaw over at their pivot points then the internal wedge will expand the jaws so you can grip work on the ID. :headscrat

You can buy the current wedge individually although you'll pay a premium. That would indeed be an excellent lathe project.

That's odd, I posted a "thank you" earlier and it was deleted? Are the moderators having some sport? :headscrat

At any rate my first stop will be Proto to see if they can save me the lathing...which will be a little difficult as I currently have no lathe, would have to sign up for a class at the local JC, or buy my own...will report what happens.

What are you asking? I suspect if its still a production piece they would sell it to him, I doubt they would send him one under a Warranty claim etc. Does Proto/Stanley still produce that puller?

Sell it to him? No, I meant why can't they just send him the piece? How many guys a week do they have calling up asking for a 4056N ?

Well DANG ME. How did you find that you clever guy. It'll cost me more than I paid for the rest of the puller (blush) but prolly worth it! HEY HEY, it's made in USA!

Just a little googling and it took me to a Proto Puller section where you can buy just about every individual piece to there pullers. It had a link to buy online and presto it took me to the Grainger page.

I would definitely check the thread size to make sure its the right one because it is for the newer models.

A little googling of part number 4250N is bringing up cheaper prices yet..

Here I was hoping for a "build" thread.

In your first picture there are two pullers; the smaller one on the slide hammer looks like the cone would be threaded for the forcing screw/ slide rod. The larger puller has a threaded spud for the cone. Two different parts from what I can tell? The later Proto pullers use an acme thread internally and none use the forcing screw to locate the cone. Check the threads on the larger puller, my Proto pullers have a major diameter of .865 and 14TPI.

Well, two "yokes" if you will. The replacement nut would fit the larger yoke, which is 14 x 7/8 I believe. The current rod screws into the larger yoke, also. The small fingers also fit the larger yoke. The only thing that won't be working for me is the smaller "yoke," it would need its own replacement nut. That can be my lathe project.
