If you can obtain a NOS or good bearing and borrow the KRW tool to install it, it is a simple job. In my MISC album there are pictures of the tool. It both removes and installs the bearing. When installing I put a grease fitting in the TT and the tool has an arrow that you sight down and line up with the grease fitting (hole), a little lube on the rubber and it pulls in real nicely. The bearing rubber collar has a protrusion that fits into a notch on the tool so it can't rotate while installing and the hole in the rubber for grease to get to the bearing lines up perfectly with the hole in the TT. If you lived near me I would come help if you found a NOS bearing. I used up what I had on my 40s.
