Stem height adjustment is a common way to reduce hand pressure, neck pain and when called for, how to improve aerodynamics. Removing the stem can be a daunting task for many but with these few steps the process is simplified:
1. Loosen stem pinch bolt(s). These do not have to be completely removed but you should thoroughly loosen them.
2. Loosen and remove top cap bolt.
3. Remove any spacers on the top of the stem.
4. Make necessary adjustments to stem height. (flipping the stem is another process that will raise and lower the stem. You will find a video for that at a later date.)
5. Place stem onto steerer tube and install top cap.
6. The top cap places tension on the headset bearings. Over tightening can damage the bearings and the frame, whereas under tightening can damage the frame. Be sure that there is no play in the headset bearings but they turn freely once tight.
7. Alight stem with front wheel
8. Tighten pinch bolts to proper torque
After taking the bike out of a trainer or stand it is recommend to check the headset bearing tension, as well as after the first ride as some bearings have a tendency to seat when ridden.
