I believe these are the two bearing part numbers.

6000-2rs
6303-2rs

Pictures of the bearings at the links below.

Thx F150, that should make things easier for me... now which one should be the one in the back?, i'm thinking 6000 but i'm not sure, and i won't be doing them both, since the front one has been replaced already.

The smaller bearing is for the rear. Looks like you also lost the rear bearing cover plate.

Take a ruler and get a rough measurement of your rear bearing and compare the size to the 6000-2rs.

The sparks you saw may be the rotor scrapping against the stator because of the
bad bearing.

Oh no, i didn't lose the cap, it was the cap flying out which finally showed me what the issue was. I went to one of the bearing stores today, didn't have the sample with me, but the guy gave me an estimate of around $6.5 for the bearing, so this should be a very inexpensive fix.

Hey guys, here is the deal: since the bearing "exploded", all that's left in the axis is the internal race, i can't place any pulling device behind it to pull it out, so i would like to hear what ideas you have, or if anyone was in the same situation, which procedure was followed to remove it.

So the inner bearing race is seized on the rotor shaft?

A shop would use a bearing separator plate and a press.


You could use a bench grinder. Grind it down in a couple of spots to weaken
it and the race should eventually break loose.
