Here's a super easy way to install a one way bearing. You take a 3/16" bolt that's about 2 inches long. Put a flat washer on the end and then stick the bolt through the gear you want to install the bearing in. Then you slide the bearing onto the bolt, making sure that the end with the writing is oriented the same way as the original. Press the bearing into the sleeve, just to get it aligned. Put another flat washer, and then a nut onto the bolt. Tighten the nut while holding the head of the bolt, and it will press the bearing into the gear. The bearing will stop when it hits the washer on the other side of the gear and be perfectly aligned. Much better than wacking one into place if you ask me.

To remove a bearing, you use the same bolt and washer, but this time you put a 10mm socket on the bolt so it's on one side of the gear, and then a larger socket on the other side of the gear. When you tighten the nut, the bearing gets pushed out of the gear.
