Thanks everyone for your responses!
The 2&3/4" is what I was looking for.
Unfortunately I don't have a bearing wrench for the table anymore and had completely forgot about the bearing wrench and rod support block size thing.
The table I am working on was mine about 8 or so years ago. I then sold it to work (to help finance a split top) and left most of the maintenance stuff in the break room with the table.
Well after 8 years all the stuff is now gone, either used or thrown away.
Jeez that table was a mess! Took me about 30 minutes just to clean the playing surface and inside walls!
I'm still waiting on delivery of the compression pins to replace a few men and handles then it will in pretty good shape again.
I might have to start practicing a little and see if my screwed up wrist can handle playing again
