Super A Trans. Sectional View

Does anyone have a sectional view of a Super A trans? There are sectional views of H, M, etc. in the IT manuals. But not any of a Super A. I have a bearing noise in the trans and PTO and I would like to pinpoint the bearing before I tear it apart. Thanks.
 
Possibly in the IH service manual, exploded diagrams are in the parts book. That transmission is very easy to work on. I had mine completely apart and replaced all the bearings. It did not get rid of all the noise, though.
 
Thanks. Mine will make a heavy bearing noise when the tractor is moving with or without the pto engaged or when the pto is engaged and the tractor is in neutral.The pinion and the final drives have been ruled out. I still need to check the noise out when it is in high (4) gear. I assume high gear is like other trans. and is a one to one lock up of the input and the main shaft. A sectional view would be handy.
 
In-put bearing can sure make tranny noises but the PTO is different most times the PTO is from the bevel gears
 
I would guess would guess a bad bearing on the transmission top shaft or a bad clutch shaft flex coupler. When in neutral, only the top shaft in the transmission is turning.
The PTO is a straight drive through the transmission, but the ground drive is always through the top transmission shaft to the lower. Not like the Hs & Ms in which high gear is straight through.
