Answer
 Hello,

   According to the parts diagram, the rocker arm shaft is a 2 piece design and is joined in the center, so I don't think it's broken.   If the shaft is not staying in place, there's something else wrong, either a stand or a pin not holding it in place.  I don't know if a 444 has the same engine or not, so I don't know if it would fit.  You can go to:   https://webparts.pvassociates.net/cnh/main.php

 to look up parts and see a diagram of how it's assembled.  Type in your model, and go to the engine section, then search for valve mechanism.  You will see the shaft illustrated as being in 2 pieces.
