Transmission shaft swap

[baggins15]

Greetings. I've recently bought a 96 KDX200. I purchase a new (used) input shaft, part number 13127-1237, and the seller sent me the input shaft for the 89-94 models, part number 13127-1175. I will not name the seller but he is well known in the KDX circle and knows his stuff. So my question is can this 1175 input shaft that I've bought be interchanged with the newer 1237 shafts.

From my research, it looks like they quit making the 1175 shafts and just only sell the 1237 which means they interchange one way, but my question is can they be swapped the other way. i.e putting the older shaft in a newer bike. They only difference is on the clutch side of the shaft, the threads stop early and there is a small metal lip on the end of the 1175 model whereas the 1237 model just has the threads going all the way to the end.

Has anyone successfully done this?

Thank you all.

Different part number usually means it's incompatible. You are confused and thinking of a part number supercession. Kawasaki will append a letter to the end of the part number if it's revised, etc. But the number itself usually doesn't change.

Try and see if it fits I guess?

All the gears fit on the shaft and everything seems to be good to go. I just hate to rebuild this whole engine then to find out it doesn't work and have to redo everything.

IIRC, the transmissions (as a whole) between the two models are completely swap-able. Individual parts I'm not sure.

From the parts fiche. As SS109 mentions, the transmissions in the E and H/220s are basically identical

Thank you all for the input. I’m gonna send it. I will respond later whether it all worked out or not.

Following up.

Ive put everything together and have been cruising the neighborhood just breaking everything in. Shifts through all the gears fine and seems to be working correctly. If anyone has to replace a new shaft with an old one of the part numbers listed above, I would say go ahead. I just slid my gears onto the new (old) shaft that I bought.

Thanks again for everyones input.

Congrats on getting it back together and running! Now ride the hell out of it
