Hi,
Pressed the bearing races into my hubs yesterday. The hubs were preheated to 250°F. The races were chilled to -10°F. In most cases, the races needed to be driven in (I'd made pressing tools on the lathe). On one of them (a rear), it just dropped in.
Scary.
Obviously things tighten up in thermal equilibrium but one wonders if the hub should be replaced. The question is: How does one determine if the fit is tight enough? Does anyone here have experience with this?

Re: When Is a Bearing Race Tight Enough?
knock them in till they wont go in anymore. you can hear it when they bottom out. the hamer will bounce back real good. they make race drivers or a big drift. its very difficult to damage a bearing race. the material is way tougher than a punch or big screw driver.
