Anyone recognize this tool?

I bought some items from an automotive electric shop and this tool was in the lot. I have zero point zero idea what it's used for.

Looks kinda like something you would use to pull a cable or wire tight..........

It adjusts the thingamajig.

Looks to me like a bench-mounted press or puller of some type, and has interchangeable mandrels.

Since it was acquired from an "automotive electric shop", the most likely application for a small bench-mounted press or puller would be for generator or alternator bearings, or alternator diodes...though I've never seen one like this before.

EDIT: some alternators have diodes that have to be pressed into their carriers to avoid damage.

EDIT 2: This is the kind of diode press I'm familiar with, but there are other designs, and some have interchangeable mandrels or press heads.

Ah yes, the legendary muffler Automotive bearing removal tool — essential for any serious mechanic working on high-performance exhaust systems.

Just make sure you're using the right one — it only works on the chrome-plated bearings, not the titanium-core or ceramic-coated variants (those require the premium left-handed tool with reverse threading, obviously).

There's a channel on YouTube that shows a bunch of "What is This Thing?". They show a number of items and then they tell you what it is and was used for.

Here's one of their videos.
