Cracked Rotor Spring Washers?

Hey everyone.
I have cleaned my old rotors up and noticed that some of the spring washers on the rotor bobbins are cracked.
Is this an issue that would require replacing the rotors?

Re: Cracked Rotor Spring Washers?

looks normal to me. mightve been designed that way, so when they heat up and expand it can do so without warping

You should listen to me. No, seriously, listen to me.

Re: Cracked Rotor Spring Washers?

Those are "clean" enough to suggest that they were made that way. Do you have others that aren't cracked?

the spring washers on my GSXR and Bandit both have a slit like that. If there's no substantial side to side play on the rotor, I wouldnt worry about it

Re: Cracked Rotor Spring Washers?

Thanks

It took me a full day of cleaning to get them looking like that. it paid off.

The cracked spring washers are random. i.e. not all washers are cracked on the same rotor. I checked the other 89 i just bought and it does not have any cracks in the spring washers.

I might run them as is and change if there is an issue.

Re: Cracked Rotor Spring Washers?

I do agree the cracks look very clean and straight. Like they are meant to be there. Just odd that they are random placement and not all are cracked.

Re: Cracked Rotor Spring Washers?

I wouldn't worry about it to much,,we used to pound the daylight out of those wave washers to float the rotors on our racebikes,i even went as far as making a big bunch of new stainless steel replacement bushings held on with circlips like the race rotors,they looked great,gave the opportunity to take a skim off rotors on a magnetic surfacer to make them new again,still have some kicking around somewhere in oil cooled gixxer hoard.
