I pressed in the rotor bearing and its a little off with the tooth. I was wondering if it has to be totally in the spot or if the way I have it is fine. It went in so tight I dont see it ever moving in there. What do you guys recommend? Here is a picture of what im talking about.

While I would not personally use it (new bearings are only $25 and easy to press in), it should be fine.



Ine the future, line up a square on the new and draw a line to reference the indexing tab to the other edge. Then merely line up your drawn line and press the bearing in. That way, you don;t have to eyeball it and it presses in straight everytime.



Simple and effective.

Yes. Re-do the bearing install.

I think these guys mean redo it with a new bearing. When you do what you did you have deformed the bearing creating a high spot that will be a hot spot and cause bearing failure.

Actually I took the rotor and put it on my e-shaft and spun it around. Took it back out and checked and there isnt really any high spots. Just some friction marks here and there from turning with no oil. There wasnt even any parks around that area of that lip. Anyways, I ordered a bearing and I'll have atkins press it in for me. Its only $10 a rotor and if they mess up, its their problem to get a new bearing.

I just had an idea, and maybe someone already suggested this, but wouldn't it be more of a fool proof way of pressing the bearing in on-target if you use a sharpee marker or something and mark a straight line, straight down, from the point of the indexer on the outside of the bearing?

i doubt u will see scraping on the part where it would hot spot, it would have to break in and turn at a hihger rpm then what u can replicate.
