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). | 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). | ||
Be very careful to hit only the outside of the race. Even just a light tap on the inside of the race could ruin it. | Be very careful to hit only the outside of the race. Even just a light tap on the inside of the race could ruin it. | ||

Don't install the races upside down. This is impossible with oem parts and should be apparent with the tapered bearings. These diagrams show the taper of the bearing and race. The race fits into the stem (frame), and then the bearing fits into the race. | Don't install the races upside down.

Lube everything up liberally, making sure you work the grease into the bearings well. Spin them several times and then re-apply to ensure it's getting deep into them. Put an extra bead just above the bottom bearing, as it will get forced down into the bearing when you install the forks and the bearings seat the grease in properly. Do the same for the races. | Lube everything up liberally, making sure you work the grease into the bearings well. Spin them several times and then re-apply to ensure it's getting deep into them.

Slide the triple tree up into the frame. Now you'll be installing the upper bearing. Take the upper bearing (#99-3504) that you already worked grease into and slide it, small outer diameter side down, onto the tree (looks this \ / ). You will note this seems to stick up a bit - it does - and your bars will be a bit higher than before. Take the smaller seal (#33-1005-1) and place it, metal side up, onto the bearing. It should almost 'click' on, and on top of this you will place the dust cover and then the stem nut. | Slide the triple tree up into the frame. Now you'll be installing the upper bearing.
