Boy did I get lucky. Generator.

The last thing to happen before I put the bike away last year was the generator quit. I have a big battery so I managed to drive a hundred or so miles this way. It had one of the cheap generators on it so I got another one to put on this year. Took the old one off today to find this!

The lucky part is that I can find no damage to anything. No chipped gears. No filings. Not even scratches on any gears. There is a little tiny scratch on the inside of the gear cover. Like I said, I drove the thing like this for awhile. This could have been BAD!

Well, you were lucky there. Quite a lucky bit of damage. Looks like you or someone run with no backlash in the generator to idler gear. Probably even lesser back lash to create a preload condition on that shaft, enought to cause a flexing action to crack itt. If not, it may have been run that way by someone else and got chrystalized, unkown to you. These old generators dont work very hard like a hydraulic pump might. ....neat pic......joe

Not like there is a lot of adjusting you can do for backlash. It never made any strange noise in that area. I did notice that it had the 14 tooth gear. I have a 13 for it now. I mentioned that it was the cheap generator as a warning to others. At $89 I thought I couldn't go wrong even if I had to replace it every year or two. This kind of damage never occured to me though.

I have to agree with Joe on this one. I tried one of the cheep import generators last year and found that the threaded mount holes in the generator where to far off that it would not bolt in. It had to tight of interference with the idler gear. I took the mount plate off of a old burnt out OEM generator and put it on the cheep import. It bolted in just fine but did not work all that well compared to a OEM generator. I had to have the RPM's up just to keep the lights burning. I ended up buying some new replacement parts and rebuilding an old OEM generator and found that it worked much better when the import.

If you plan to try another import. I would recommend lightly bolting it in place with the cam cover off so you can check the fit for any gear interference. Use some thick flat washers to protect the engine case.
