Steering head bearing question
My '07 300 needs to have the steering head bearings replaced. I can't get the bottom 1 to come off the steerer tube. is this thing pressed on or something? or do I just pry it off with a screwdriver or something?
Thanks! |

It's pressed on.
You can apply some heat to the bearing and it will slide off. |

Thanks, GGMan! & to put on the new 1, it's the same I presume, a little heat to get it on?

throw the race in the freezer to shrink it a bit. Heat the steering stem to expand it a bit. slap a little anti seize on the steering stem. pop the new race in. Some times the old race can be used to bang the new one in place. I really don't know if heating the steering stem where the race goes in expands it that much ... but its good for psychological reasons!!!

Don't cool the bearing to do on the stem. You'll make the ID SMALLER, and harder to get on the stem. That's going the wrong way.
If anything, throw the bottom triple clamp/stem in the freezer. You'll shrink the ID of the stem, and the bearing will go on much easier. |

Exhaustive discussion here:

You are talking about the outer race that goes in the frame. You are both correct.

The poster is talking about the bearing on the STEERING STEM, not the bearing race which goes into the frame.
You want to cool the stem (reducing it's OD), not heat the stem (which would increase the OD). You don't want to heat the bearing as you'll get the grease to outflow. |

Skid was adding to the discussion.
If the steering stem bearing is being replaced, surely the race will be replaced also. A "heads up" kinda thing. |
