John Deere 826D Drive Won't Engage

Hello,
Sorry for the double post: I posted this on the John Deere forum a few days ago, but there doesn't seem to be much traffic on that board.
My dad's 826D is having similar symptoms. In this situation it looks like there is some sort of retainer clip that is missing, allowing the pinion shaft with the chain sprocket to slide off of the gears (allowing the grease fitting end of the shaft to slip back into the drive compartment, which makes the drive disengage). Either that, or maybe a roll-pin/cotter pin, but i dont see any obvious holes for one to be inserted. I can't find anything about this specific piece on any parts diagram, and a call to my local dealer was no help, so any help would be appreciated.

As a very unscientific test, i bent a piece of sturdy wire around the grease fitting, and the drive worked as it should, but i can't imagine that to be the proper solution.

Thanks in advance - Sorry the site wont allow me to post photos since this is my first post.

Off the top of my head is there a channel that a c-clip slides on to to keep the bar from sliding out?

kinda looks like it, but that might just be the nipple of the grease fitting. Also, the paint isn't worn away like you would expect if there was a retainer clip riding against it

Is the opposite end of shaft welded to frame, I can't tell from pics, also measure the frame side to side at top and where the shaft is, maybe the frame is bowed out and the shaft can't stay in place?

the frame seems to be square from the factory. The shaft is captured by some sort of roll-pin on the outside of the housing on the non-gear side of the pinion shaft. I'm wondering if there is a 2nd hole for another pin just inside of the frame on the right side of the shaft? Nothing noticeable, though....

I can try next time i'm at my folks house, but i'm not sure when that will be.
The other end of the shaft goes through the housing and is captured by some a little roll pin. If i didn't know any better, i would expect there to be an identical pin, preventing movement in the other direction, either on the outside of the housing on the grease-fitting side, or immediately inside the housing on the non-grease-fitting-side. Just something to prevent that shaft from sliding. Can anybody think of an immediate objection to drilling a hole and inserting a pin inside of the housing, on the non-grease-fitting-side to achieve this? That way there'd be a pin on the inside and the outside of the housing, preventing that shaft from sliding laterally.
