RE: One Way Bearing (450-SA)?
It is pressed in there. Most shops have the bearing press tool that you can use in combintation with a vise, or c-clamp to get the bearing out.
There is a better bearing than the Align one: I got mine from helidirect.com part# HF0612
When I pressed mine out I used a couple of 1/4 sockets, one slightly larger than the bearing to catch it and hold the gear, and another smaller one to press the bearing out.
