What is This Tool?

07/10/2017 3:06 PM

What is this tool, what is it used for, and how is it used? Turning the screw causes the jaws to open or close. From the shape of the jaw tips, and because the screw and jaws can not be adjusted independently, it seems this is not some sort of gear, bearing, or battery clamp puller.

It's a Bearing Puller.

Depending upon which direction (in or out, I can't tell from picture) the lips/catch face establishes whether it's in "inside" or "outside" clasping puller.

Looks like an outside-clasping puller, but I can't tell for sure.

Maybe it's for compressing c-clips that are used to hold the bearing caps on universal joints, (the bane of my existence as a former owner of a Triumph Spitfire).

And all you needed to do was pay a few dollars and you would have easily removed them.

A tool for holding the ends of drive chain so the splice link can be inserted.

I've seen this tool before but I will be damned If I can remember where. However, Tornado's answer rings a bell

I also have a tobacco pipe reamer that is basically the same, just turned backward with a variation in jaw shape.

What else have you been reaming?

They used to call those brushes, or so I thought.

Tornado: Correct! It has no hooks, so cannot be a puller. I think this is for smaller chain, both to remove and to insert links by taking the tension off. Even hanging loose, a chain has tension due to the catenary forces. The tool would be considerably heftier for the heavy drive chains on trucks and industrial machinery.

These tools come in a range of sizes. Each size can typically handle two or three consecutive pitches of chain, but it takes several sizes to span the whole range of chain sizes. I have dealt with chain from 1/4" to 2-3/4" pitch, plus a weird specialty of about 6" pitch (Incolloy crab cooker)(pretty good story if anyone wants to hear about it).

With slightly modified jaws, this tool is used to remove battery terminals.

It is a nut grabber for those difficult small animal castrations. Hamsters, guinea pigs, cats...

Otherwise it is a puller for really small pulleys. That is why they still call them pulleys.

I dunno, but think I saw a fellow once that had a case of the "pusheys". He had to be placed in a straight jacket before it was over.

Have you ever tried pushing a drive chain?

It could be a kind of spring compressor.
