The thread you posted does not confuse me. I am looking to do the same thing. That is, find the correct bearing, knock out the old bearings, and knock in the new bearings. I understand that pressing is preferable. How much did you pay to have the bearings pressed? What sort of shop does that work? I am correct in assuming that the pressing only takes a few minutes with the proper press tool?
Interesting that your idler pulleys required the 6301 bearings. That is the same bearing number that the idler pulleys on the G50 uses, which gives me hope that my Y33 idlers will also take the 6301 bearings. The 6301s are cheap and available from Amazon with prime shipping:

Great to hear of the compatibility and relative cheap cost. I can't recall why I had such a hard time locating the proper 6301 bearings. Maybe it had something to do with the load rating.
I took my bearings to a machine shop after pounding one out of a pulley and quickly losing interest. They charged me no more than 20 bucks to press all the 4 bearings into 3 pulleys. IIRC, for such small bearings, their rate was 5 bucks to press in, but free to press out if it was done at the same time.
This shop typically presses bushings, rebuilds engines (assembly stuff) - but some will also have drills, mills, lathes, welders etc...
A good press such as an arbor press will definitely do the job at home. Most of the time was spent locating the right adapter for the bearing and aligning it. He sprayed some lubricant on the bearing and seconds later had it seated.
