I was looking for a late model, 2007+ big twin primary bearing remover and installer tool. I already have George's Garage tool #590070, but that is for model years 2006 and earlier.
Spoke with George today and he told me the tool (or necessary adapters) should be available in a few weeks. They just picked up the bearing and are working on it.

Another option is Jims USA, tool #729, but their tools are typically far more expensive.

I do own a 12-ton Harbor Freight hydraulic press, but I'd rather use the specific tool if available for this application.

 

Use your press that's what it's for
