Rotor gouge

[Bob Shaw]

Hi All,
I have a 1982 gs850g. I have to change the stator and while removing stator I saw a gouge in rotor. In checking the stator I see where a piece of the stator shifted and moved. Because of the gouge in the rotor should I change it or will it still function properly. The gouge in the rotor is in one spot?
Thanks..

Thanks.

Picture not showing up.

Look for cause of this gouge...maybe a screw got between rotor and stator. Go fishing with a magnet- make sure the stator wire clamp screw is still in place.

There are no missing screws, what I need to know is if I can still use the rotor..

Try sending pic again- you need to make sure that the embeded rotor magnets won't come loose

I'm going to be on the safe side and replace it. If there was a loose screw or nut it would have chewed up more than what has been done. This is the first time I had the stator out due to charging issues. I've had the bike for eight years who knows when this happened. Thanks for your help, I appreciate it.

No way we're going to be able to help you without a working pic.

 

[Bob Shaw]

OK, I'll try to send a picture.

OK I have the pix but how do I download them to this site?

Upload the picture to a hosting site, then copy the IMG link and paste it in your message.

No need to click on any icons here or anything else, just paste the IMG link.

If you have more than one picture, at least make sure you press ENTER between the links.
Better yet, press ENTER twice, it will give a blank line between the pictures.

I'm trying to cut and paste the pix but no luck. By this you can tell how computer savvy I am.

 

[JTGS850GL]

You don't cut and paste the actual picture. You host the picture on a site like imageshack.com or tinypic.com and cut and paste the link to the picture here.

 

[Bob Shaw]

OK, I'll try that.

I can't see a photo either, but how deep a gouge are we talking about here?

The rotor is a really thick piece of cleverly magnetized steel, and unless it's been somehow gouged out to the point where it's in danger of falling in two pieces (you would need some serious tooling to do this on a lathe, let alone inside a running engine), I can't imagine how it would cause a problem.

You should do your best to account for the remains of the screw or whatever caused the issue and the shavings created -- I would definitely drop the oil pan and clean the oil pan and strainer screen.

 

[Bob Shaw]

I sent the pics and apparently they did not get through. The gouge is about 1/8" right at the seam where two plates meet.

Hi again,
I put in a new stator from OEM cycles and a used rotor. I ran the checks to see if I have 75 volts on a AC voltmeter and come up short 61-71 volts. My battery is not recharging. Is there another test I can do or is change the stator and start over?

 

[tom203]

60+ AC volts is adequate.. Did you happen to measure the AC vokts from any stator lead to a good bike ground on same meter setting? You want close to 0 volts.
If battery isn't being charged to at least 13 vokts, it seems that your r/r isn't happy or your connections are wrong.

 

[Bob Shaw]

OK, Thanks, I'll check that out.
