Here is a brief tutorial on Crabbing the Spine Frame.

 

It can be done!

 

Measure your swingarm offset BEFORE you remove the pins. (don't ask me how I know  . . . :blush:

Hallo Guys!Easiest half job done-transmission off!Is anybody taken gear box aparts?

Posted

Good job so far. Move on, you'll get it going again soon. Alas the parts probably will be everything but cheap. How many miles/kms has the gearbox done so far?

Miles is only 19,800 :huh2:  I do it everything by myself so no labor cost,Gear whit broken tooth is part of Primary gear shaft assy  and cost £577.70 inc. VAT :mg: But I have other plan I send shaft to Poland where engineering co. Make new gear and fit back on shaft.

Good work! Is it cost effective to get the part made in Poland rather than in UK?

I think that picking up a used gearbox, on the long run at least, would be the better solution. Loosing teeth is not what I'd call proper ageing for a gearbox. Have you noticed the pitting that has already built up? Unless you haven't been really rude to your example I'd say you just hit this one box that shouldn't have passed the quality checks at the suppliers.

Having your F/F make a new wheel nevertheless is a good idea. Those normally like some challenge from time to time :)

There was no other since except missing teeth,and I never was rude, event more I was always gently.I thing You  probably right, gear could be over hardened?My F/F after cutting new gear He gone send it to induction hardening

Posted

I think it is excellent and very extraordinary that a gear would be made for the problem.

 

Amazing, really!  :thumbsup:

The tooth fairy better pay top dollar for that lost gear tooth!  :grin:

 

Looks like a painful operation to make. Best of luck on your gear replacement, I will certainly take note in case I ever run into such an issue.

How about a "Forum Hero Of The Month" award?

It will be interesting how the new and freshly hardened gear will go along with its already worn in counterpart. I hope the new gear wont eat through the old one all in one bite.

And so I ride 200 miles after  repair and everything works great!!! What more it seems to me that using shockproof gear oil, gear changes  smoother!
