Was wear resistance the issue? I thought the shaft was breaking, but could certainly be incorrect about that.
1) drain oil and coolant
2)remove left crankcase cover
3)locate shift stopper lever in bottom left and remove it (one bolt)
4)replace with new stopper (the spring will be a pain to get back in place, just zip tie it to the stopper then remove the zip tie when its bolted up)
5)replace cover
6)replace fluids
Done
I asked Yamaha for the replacement 1SM-12450-09 and they only have 1SM-12450-01 listed as the updated part.
Problem is the replacement impeller shaft is different and doesn't fit! Yamaha here don't have any knowledge of the -09 replacement part number. Unfortunately Yamaha race support here South Africa is is terrible. Can anybody shed some light on this, maybye somebody from a Yamaha Race team?

But the look on the impeller that you got looks to be like a 450 water pump. The 450 water pump has that straight edge on the tip of it. Was the package opened when you got it?
That info helped a lot, didnt think it may be a 450 part. the package was sealed. Im off to Yamaha now to try resolve it they must order the another with the same part number and we will see if they same arrives, may be a factory packaging problem.

So if the package was sealed.... I would say its a mis-package by Yamaha.
Hope everything works out.
Because even though you order the 15 pump, some parts grabber could see that the old one cross references and send you that by mistake as well.
I wish you good luck with this. I feel a bit guilty, as mine was so easy to get.
Problem resolved the part was incorrectly labeled and was indeed a 450 impeller. reordered same part number and the correct impeller arrived.
Something to be wary of, check the parts carefully, don't simply trust part numbers.
Thanks for all the assistance.

addressing the small stuff save big $$$$ in the long run.
Changed ours out, no problems prior or after.
You can change the stopper out with-out removing the Clutch Basket. Take your time and with some mechanical know-how you can do the swap at home.
Cheers!
