Each V-Wheel consists of four components:
Press one bearing into the v-wheel.
Make sure everything is straight
It can be easy to accidentally press in a bearing crooked. Try your best to avoid this as you could damage a wheel this way.
The sound of success
If all goes well, you should here a satisfying ‘pop’ each time a bearing fits into the wheel.
Insert the precision shim such that it is resting on the first bearing on the inside of the wheel. Try to position the shim in the center of the wheel.
Press the second bearing into the v-wheel.
Shimmy the shim
If the second bearing doesn’t seem to fit all the way into the wheel, its probably because the shim is misaligned. Use a small screwdriver to push the shim into the center of the wheel, and then push the bearing in the rest of the way.
