I believe fig f0119 refers to 2n and 9ns. All further references are to fig F0121: There is a bearing race (cup) #13 pressed inside the bearing retainer #12 which should be changed if pitted or damaged. The bearing cone #17 is pressed on and can be removed as described below. I wrote the following after changing my bearings out. I hope is is clear enough to be useful. Race: (cup) F0121 #13 Cut a piece of 3/8 X 2 1/2 cold rolled flat stock to 3 3/16 inches long. This just fit inside the notches on the retainer #12 and caught the lip of the cup. Simple after that, mounted it in the vise and pounded alternating sides of the flat stock with a 16oz hammer until cup came out. To install new cup, I used old cup between new cup and hammer to prevent damage to new cup. Slowly working around the cup until it was home. Bearing cone: #17
Mount axle w/ bearing in vise. I used the broken front spindle that I'd thrown in a box as a drift to drive the old bearing from the axle. To install new bearing, I spotted it squarely on the axle, slid the old bearing on the axle to protect the new bearing, and slid my T-post driver (a pipe the right size would work) over the short end of the axle to pound against. Stood the axle on a wooden block on the floor. I stood on a stool and drove the new bearing on using a 3 lb hammer. Took many blows, but got it done. Slow and sure. If you are uncomfortable doing this, a machine shop can do it for a couple of bucks. Experiences and opinions stated here are my own and may not be based on valid memory or sound judgment. Personal responsibility on your part is required. Good luck. Steve 8N 169302
