800/841D or Industrial, clutch parts conflict

I have a used Ford tractor. From what I could find out it seems to be a 841D. SN# eaten away via battery acid or just weather exposure . I was fine with that. But, it came time to replace the clutch. 1. clutch plate is a 10", 1" 15 spline with a 2" wide contact area as apposed to the typical 1-5/8". NO PART NUMBER that I can find. 2. The release/throw out bearing has a grease way. Aetna #2256-30 AKA All States Ag Part #1428650 maybe. It can be greased via a zerk and hose mounted to the bell housing to the hub. 3. The release bearing hub has no typical part number that I could find because, of the approximately 1/4"NPT or FIP tapped fitting. It is stamped "CONN" "7571-A". I found 1 of possibly 4 in the entire world. I had to order it via Ford/Newholland Tuscon Az. SO WHAT KIND OF TRACTOR IS THIS WITH THESE PARTS? I saw an old Ford brochure that showed an Industrial that looked like a 800 series. So, I'm not sure. Any body had any experience like this, or any resolve?

I have a couple like that, grease fitting on outside of bell housing for heavy clutch work. I think only 4 speeds have those. Mine is a 4030 with the 4 speed and a Sherman reversing transmission, you can go just as fast backwards as forward. I wouldnt do it in 4th. They also have a Sherman that gives you a high, normal and lower range. I think you can install them in any 4 speed tranny. The Shermans take the place of a regular 4 speeds input shaft. Was your old hub worn out from not being greased?
 
I don't have a Sherman reversing transmission as you have described. That is scary, I wouldn't want to go 20 MPH or more in reverse. I have a 4 speed with a reverse, and a high/low lever (a Sherman style), not sure about the normal. The poor release/throw out bearing was never greased as per the last paint job, (not mine, many years ago) and my neglect, as it was covered with dirt. But, the bearing is still is very good condition. Except, it is now is loose on the hub, which defeats the greasing path way, as it rotates, when it should not.
To answer your question, no, I don't think so. It may have been replaced by the previous owner(s) without the rearguard as it should have been a press fit.

You put the Sherman shift handle halfway between low and high and then push the entire handle and shaft inward toward the center of the tractor, and once it's slid in pull it back (I believe, but it's been a while so it may be forward) then it should be in "normal" range, which is the factory 4 speed gear ratios without the Sherman involved.
 
Post a picture. Clutch plate and bearing. Old vs replacements?

The 4000 Industrial. Just like the 841D?
It did have some yellow on the trim at one time. But, also gray read mostly on the engine and 2 shades of blue. Now another darker blue and white.
