Bevel gear swap question

Hey fellas,
 
I know a number of you have updated your bevel gears, so I figured I'd ask you if I got the right parts here or not.  I have an 650H1 motor, and I removed the bevel and secondary drive gear.  However, the secondary drive gear looks very different than the one that I removed.  Yes, I understand they are straight cut.    The changes are as follows:
 
OLD:
-Had large nut facing the inner driveshaft that kept the driven gears on the shaft
-The two secondary driven gears could come off the shaft
-The shaft went through the side of the case and the end of the shaft went into the "Secondary Shaft Bearing housing"
 
NEW:
-Secondary driven gears are welded to the shaft
-Shaft that goes into the "Secondary Shaft Bearing housing" is partially threaded
 
Everything seems to fit and such, but I don't see how I'd use the threads as no nut came with the kit.  Do I buy a nut to put on there or something?
 
Here is a pic of the inside of the cases showing the difference between the old and new driven gearset:

 
Here is a pic of the outside of the cases showing the difference between the old and new driven gearset:

 
Is this all the right setup?

    Does this help?
     

     
    I'm pretty sure you should've gotten a new nut in the kit.  Maybe you reuse one.  I can't remember.

    Dig through your package again.  It should come with a new nut for the back side of the new drive gear.

    OK, I got it.  Thanks for the parts fiche.  I tried looking up the fiche from a 2010 650H1 and it had the old helicial gear setup.
     
    Thanks to Sodbuster for his help on the phone last night.  Not sure if I was missing some instructions or something, as there was no instructions on how to install the driven gear.  Found the nut...didn't know I had to shim the driven gear either. 

    This is the first time I've gone into an H1 motor, first time ever doing gears, first time working on the internal tranny gears, etc...  So in other words, I am learning a LOT....and without instructions, it's a bit of a trial and error gig.  :)
     
    So, I got the driven gear shimmed with a 1mm shim, and got my drive gear shimmed to the point where it spins freely, and has just a tick of backlash...can't feel it, but can hear it, so from the sounds of it that's right where I wanna be.
     
    I don't be doing the mud thing like you all do down south.  I have some trails, some mud, and some work.  Largest tires I'll have is 28's...more than likely, 27's.  Remember, I don't have the deep nasty stuff like you guys do, so the larger super aggressive mud tires aren't really a necessity for me. 
     
    I'll keep you updated on how things work out here.  Thanks for the help!  It's more than greatly appreciated!

    Yep, the 2 #9's in the pic I posted are where to shim it.

    I'm changing them out NOW before I have issues later.  :)  This is a motor I bought to build up, so I got the gears cryo'd and am doing everything else I can to make this a stout and robust motor.

    Didn't know I had to shim that 3rd gear too....dangit, thought I was in the clear.  :)
     
    I am taking pictures and videos so once I'm done, provided everything works out, I'd like to make a "how to" document.  I won't go through the whole motor tear down process, but will show how to replace the bevels....again, that's my GOAL.  Whether it works or not is yet to be determined.  This is my first rodeo, so we'll see.

    Yes you have to shim to bring the gear in and shim the other to bring it up to mate each other. Shimming is the most time consuming in the whole process. Take your time and you will get it.

    I have time....I have more patience now than I did 5 years ago (thank you children), and I've got guys like you who are willing to help a fella like me out (thank you very much!!).  I'm good go to.  I'll be working on this hopefully Sunday or tomorrow.  Had a friend die yesterday (lung cancer) so between the funeral and such, it'll be a bit tougher to work on it as planned.  BUT, I have time.  My 650 motor that's in the quad now runs fine and strong, so I don't need this motor built to ride.
