Good tool, but must be hand drilled to accept bearing installation cup
Good tool, but you have to drill a hole in the bearing installation rod to accept the cross bolt that locks the bearing installation cup onto the rod.

I'm not sure what they're selling.
Gimbal extractor works. One of these guys needs to come down here and show me how the installer works. There is a driver for the bearing with pin but the driver rod itself has no hole like shown in the picture. How do you miss that?
