===Bearings in the steering head===

Take the larger bearing race (#99-3503) and install it on the lower part of the frame's steering head.

Take the larger bearing race (#99-3503) and install it on the lower part of the frame's steering head. To do this, get a piece of pipe that's a teensy bit smaller on the outside diameter than the race, but large enough so it cannot slip into the bearing surface of the race. You want to apply pressure all around the edge of the race without touching the inside of it. You can also use a socket of just the right size.

~~'''<<<Can you use the old 'correct-sized socket' method for~~ this~~? Lots of people don't have access to different sizes of pipe, and PVC only comes in certain standard sizes, as I remember.>>>''' Like this guy, halfway down:~~

PVC is safest for not damaging the metal but harder to find the correct size. Take the bearing to a hardware store and try to find the correct size. PVC is the first choice; a socket or metal pipe second.

If the part of the pipe you are hitting is wider than the hammer, put a flat piece of metal across the pipe, so the hammer blows are transmitted to all edges of the pipe equally (or use a wider hammer).
