Good day, I thought I would throw up a few photos and a write up on how I replaced my outer crank bearings as it was way more simple then I had anticipated. First I pulled the bearing using a gear puller, this may not go as smooth for others as it did for me. Once I put tension on mine and gave the outer ring the smallest tap it popped right off. I then measured the bearing, inner, outer, and width to find the dimensions, with my best Nova Scotian memory I believe they were 25 X 62 X 17 which equates to a C3 rated #6305, but don't go ordering bearings for your RD based on those numbers, measure for yourself. There are also grooved and pinned style bearings, you need to know what you need and how to ask for it, consider this
CAUTION NUMBER 1. I made some calls and found a local millwright who could get me the bearings for $7.50 each, and it only took 24 hours to get them. I placed my cleaned crank into the freezer overnight to shrink and in the morning I baked the bearings on a cookie sheet to between 175F - 180F. I had a hammer and a deep socket nearby thinking I would need to apply some horizontal thrust, but to be truthful the bearings slid right on and stayed in place. Although I had heard of people using this method in the past, this was COMPLETELY EXPERIMENTAL for me. I DO NOT in any way suggest you do this or consider any of this a HOW TO demonstration. It's just how I did it, and it worked well for me.
THAT WAS CAUTION NUMBER 2. Pics below, PS: The bearing oil seal is easily removed with a seal pick and as I wasn't sure how this process would go I did one at a time.
