I just hope it is repairable, and that I can find the parts for it. It is not a good sign that the only place I have seen parts for this thing is RP.
There is always the original motor that I had on this scoot, but I hate to rob parts from it.

Not bad, but bad enough. This engine has the machined bearing on both sides of the gearbox. The one on the small case side seems to be fine, but the one on the large half of the gearbox wore into an oval. I can wobble the gearshaft about 2.5 mm total. I may try some type of repair like 90GTVert did. I cant stand to loose the time I invested in porting the cases. This thing was sweet the short time I rode it.    |

I don't even know what to say, other than I hope you can fix it.

Ouch! yeah, id at least try to fix it somehow. like you said with using 90gtvert's repair technique. at least that way you can still use the engine cases.

That's the one I was thinking of. Hopefully it's not to bad to repair. Just a thought maybe you can enlarge that hole, and make a "cap" for the shaft. May be a bit easier.

When Brent was looking for solutions I was thinking of drilling all the way through the case and pressing some kind of cap in place from the back side. But it may be simpler to cap the shaft itself as you suggest. |

I was looking at Universal joint bearings, but the shell seems to thick. Thanks for the link! Those look like they would work better. |

If you have access to a machine shop I would have a oilite bushing made and pressed in. Bushing wall thickness of 1/8" should be fine. You would only have to bore/machine the case out 1/4" larger to press in.  |

You would only have to bore/machine the case out 1/4" larger to press in. This is exactly what i was thinking. Just have the hole machine out and put some (copper) bushing back in. I once had a Honda MB-8 engine where the crank bearing seat was totally worn out. I had the bearing seat machined out about 4/5mm's. Had a thin steel ring machined with the depth and inner dimensions of the engine's bearing seat that i had put in the machined out bearing seat. Worked fine! |

Worked fine! Recently repaired a gearbox using the method you describe. I have not bothered to work on it myself yet because the ONLY place I have been able to find a new primary shaft, and gear is Racing Planet, and they want over $300 USD for them! Malossi makes a primary upgear set that takes my stock gearing of 10.65 to 6.92 I dont think that low of a gear would work well at all so I am in no hurry to attempt the repair. |

I recently purchased a set of SC10 cases from feebay. They arrived today and although they are the greasiest cases I have ever seen, they are in great shape. I purchased them mostly for the gears, and thankfully they are in great shape.
Since the gears are so good in this new set of cases, I may just bite the bullet and port these new cases for the Corsa kit instead of using the gears from them in an attempt to repair the transmission I screwed up, at least for the time being. I would hate to screw up a good set of stock gears trying to repair my existing gearbox. I still cannot find stock replacement gears for less than $300+.
As I previously mentioned I can get a Malossi primary upgear set for a reasonable price, but it brings my gearing from 10.65 to 6.92 at the box, which is very tall IMO. I may try them anyway just to see what happens, and to find out if my repair plans for the transmission will work.
