Puller most likely, but (I think) it could also be a chain breaker. Although that would be one big chain....

It removes the orifice from inside of a Falange valve.

It is a puller of some sort, likely a condition where it can't get inside the part.

It looks EXACTLY like the tool I could use to pull the empellor off it's shaft on the Kubota snow blower, "nearly" all in pieces in my shop.

What size is the hole in the split clamp part?

First thought that came to my mind was a press/puller for "U"joints (aka crossjoints).
