Urgent! Any Differences in Yamaha Secondary Clutches?

[ArcticWhite]

I have a 2010 Nytro MTX. One of my secondary sheaves has a crack large enough to see through.

I found a used 2003 RX1 secondary clutch that I am considering getting rush shipped to me today.

Are the fixed and movable sheaves on 2003 and up RX1's, Apex's and Nytro's all the same?

I will transfer my helix, spring, etc, I just need to make sure the two sheaves are the same from a 2003 RX1 as my 2010 Nytro MTX.

Also, are there any differences in the secondary between sleds with reverse and sleds without reverse?

Thanks!

I have not tried to swap parts, other than the obvious tuning parts. But I can tell you the jack shaft is different on the two sleds so it won't just go on. There is no difference in reverse/ non reverse though.

I looked them up on the online parts and RX1, Apex and Nytro all show different part numbers for the sheaves (8CR, 8ER, 8GL). Since there are no definitive responses on this and since I don't want to chance it, I guess I have to purchase a Nytro secondary.

The nytro secondary clutch is different .....apex,vector,rx1 or any other will not fit

 

[nytrolabrador]

no doubt it will not fit..

Thanks everyone! Ended up finding a 940mile 2ndary clutch out of a 2011 Nytro. That should get me going!
