88rotors

Did a disassembly of my motor to do a rebuild and clean. I have this rotor I'm worried about. I wouldn't mind repairing it, but I'm not sure if it's repair-able.

Thanks.

If you got a file and carefully filed it out you should be ok. Is that the only bad corner? Almost looks like it was dropped on accident

Unfortunately, it sat in someone's trunk and got flung around for a day. I'll get some more pictures of the other side, it does have some issues on the other side of the rotor too.

How would I go about fixing that with a file?

bend it very carefully and file it back to specs, you should be ok.

You'd take a file thats 2mm think, and slide it in and out "ahem" until its nice and smooth

I finally got around to getting another picture of the damaged rotor. This time with the side-seal location and corner seal location.

If this rotor is crap, would I be able to use

In my 88 13b rebuild?

that rotor is no good

Thanks, I was worried about that.

I'm looking at getting a new rotor. I read on the forums that as long as they are within one letter, I can swap out a rotor without having to replace them as a set. Anyone have some input?

I believe my rotors are E, so would a D or E rotor work just fine?

If the rotor is not the same letter, you could always get the compete rotating assembly balanced, then you would not have to worry!

So if the replacement rotor is not the letters I need, I can just send the whole assembly to get balanced? I could go grab a C or B rotor?

There is an auction listed two posts or so up that have a set of rotors on sale for 200, would that be a better investment? If I did go with those rotors, would I have to get another shaft, or would my original one work? Just trying to make sure I have all the things I need before my rebuild.
