5400 silage chopper

Taking the engine out of this chopper, is the rear wheel assist worth anything? What should I take off before it goes to scrap?
 
The RWA spindles of a 5400 chopper are EXACT SAME PART NUMBER than a 4020-3020-4320 factory front wheel assisst...
So yes, it's worth 1500-2000 at least.
 
Sure.
One nice thing about the 5400 motor is that it is exactly the same as a 6030/7520 engine. You got the external aneroid controls and the same exhaust elbow than a 6030 + same valve cover.
This is important if you want to install a 6030/7520 air filter on a 5020 motor the "factory way". If you are putting it in another application, i think that you should sell your exhaust elbow to someone that really needs it, and use a common "8640" one.
 
This is going in a 5010. Is the 8640 elbow shorter? Therefore getting it closer to the original opening in the hood.
 
Pretty sure that they are exactly the same.
There is a guy that put a chopper engine in a 5020 on "Farmphoto" forum. He reused the orgininal chopper air filter and managed to put it under the hood with the original SCvs.
Farmphoto does not work anymore, but you can see couple movies of it:

The repower is a challenge with same hood, because the radiator should be moved forward. You need to replace the 5010 radiator support with hydraulic cover plates of a 7520 tractor + shorter grill screens and that should do it.
 
I was hoping to put a 619 in it, but this deal came along and chose this instead. I will check out the videos regarding the air filter, I suspected that would get challenging.
