AGMO R45-312 gearbox

Restoring this old bush hog that has this gearbox on it. When I tore it apart I found a snap ring that had broke in two. It looks like whoever had been in it before me had used the snap ring as a spacer on the input shaft. When I pressed a new bearing on the shaft, there's a 3/32" gap between the bearing and the bottom of the snap ring groove.

My question is, should there be a spacer between the bearing and the groove, or should the spacer go between the gear and the bearing?
I've tried to find a parts diagram and had called Howse equipment three times with no success. Howse just puts me on hold until I give up. :x

One picture shows the gap that will be there when it's assembled, and the other shows how the assembly actually goes together, with the bearing secured in the housing with a big snap ring, then the shaft goes through it and the smaller snap ring holds the gear/bearing/housing assembly together.
Any help deeply appreciated.

(quoted from post at 15:47:11 10/09/16) Hi, did you ever find a parts diagram or a place to buy parts for your gearbox ?

Thanks
No, I didn't. The diagrams at the Howse equipment site looked a lot like my gearbox, but not exactly.
I found a machine bushing at TSC that fit over the shaft and used that to take up the space between the gear and the snap ring.
I used the cutter today for the first time and didn't hear any weird noises or feel and bad vibrations, so I guess all is good.
