Large SKF/FAG bearings have these awful taper sleeves that need to be released from the surface of shafts with oil pressure. Unfortunately the threaded hole in which to inject the oil is within a few mm off the surface of the shaft, and there is generally no way to get a conventional fitting in there to inject the oil.
I made this mockup fitting for a client who has a large piece of equipment with no way to access the bearing taper sleeve using the manufacturer provided tool. It's stupid, but it's a thing that might be useful to someone, so here it is. Maybe it'll help someone in a similar situation.
