This has been in my garage for a while, but I have no ideas what it is. Anyone out there know?""

It is a gear puller. A two and and three arm, use to pull gears/bearings off off shafts/holes. Use the bolts to connect a pair of flats to the centre piece to the arms. The long screw goes in the centre hole, place it against centre of a shaft, the arms go to outside of gear and you turn the screw to remove gear from shaft.

  • Most certainly a gear-pulling set. I have a set that looks almost identical to that. – Tonny Jul 26 '21 at 10:12

    Indeed a gear puller, but often not the best one to use. A "harmonic balancer" type works better in most cases, such as flywheel removal. It uses bolts to make a positive connection. The arms on the type shown above can slip off easily, or even break. However, it does work well for things like removing boat steering wheels. – Jason Jul 26 '21 at 13:40

    @Jason Quite a few different types. Each type has best design use/size. Type above usually best for accessible gears without drilled/tapped holes. – crip659 Jul 26 '21 at 14:15
  • What's it look like when assembled? I'm trying to picture it in my head from your description and not getting anything coherent. – nick012000 Jul 26 '21 at 17:06

    @nick012000 Just do an image search for "gear puller" and you'll get thousands of pictures: https://images.app.goo.gl/H5j4f3mXekcC7mnu5 – Theodore Jul 26 '21 at 17:26

    It's the sort of tool for which you cannot find a good substitute. So if you ever potentially want to pull something off a shaft without twisting or hammering, this is the tool. Can you tell I've needed one and not had one? – Criggie Jul 27 '21 at 04:40
  • This is the correct answer and should be accepted. – FreeMan Jul 30 '21 at 14:12
