Stuffed My Disc

I've got a ferguson ABO-22 disc that I've been pulling with my old 8n. Everything has worked as good as it can for a 80 year old tractor pulling a 70 year old disc. The rear left gang of disc's has historically been an issue with occasionally binding. The lower bearing had a chunk missing since Nixon from the looks of it but nothing way too much grease couldn't fix.

Welp. I was apparently in a big hurry and whipping through a gate opening, caught the left rear outer disc on a fence post and the fence post won. The upper bearing box mounting bit thing snapped totally off from the rest of the gang frame.

So what I'm looking at is a bearing box lower that's in a few pieces, a bearing box upper that's in a few more pieces.

I entertained the thought of welding it back together but I'm pretty sure it's all cast iron and without a ton of heat it won't not crack.

I've done my best google fu an all I can find is symmetrical looking bearing boxes but nothing that has the offset looking mount from the upper box to the gang frame.

Is this even something that's replaceable? Should I try welding it? I'd hate to scrap the whole thing for just this one part. Am I able to just take that gang off and have a janky three gang disc? Just take the other rear gang off and run the front gang?

Go easy on me this is my first post 😊

Dont know if this helps from 2009.

Since it broke as a result of an unusual occurrence, chances are it could be welded, but not seeing it makes for only a guess.

Unless you are an accomplished artist with welding cast iron, best take it to someone who is. The first chance has the best odds of working.

Those are fairly easy to weld. You won't need to get crazy
with heat either. Use nomacast rod, weld an inch then pean.
Holding it in shape while welding will be the hardest. Neiva
would make it easier to give advice. You can use nickel rod as
well, but it is spendy.

When the cast hanger bearing broke on my
Dearborn years ago I just built a new
set out of steel. Made the mounting
plate out of 3/4 flat steel. Made the
bearing out of 3 in steel steam pipe
that is 5/8 thick. Welded it together
and drilled and tapped for a grease
fitting and installed it. There's no
chance of hurting the steel bearing.

that should be a claim shell/spool bearing at that age...with a support mech. the upper and lower claim shell bearing covers come with 4 mounting holes and can usually be made to fit most all mounting brackets... and the spool over the shaft can be replace to match the modern claim shell bearing... if I am understanding what broke.. agrisupply and others specialize in these parts in their catalog. I would think even this site has disc parts ... best of luck..

The issue i'm running into looking at new bearings is the bolt holes for the clam shell for the new ones are centered left and right on the clam shell. For mine like you said there are pinch bolts holding it together that are on one side, and mounting bolts on the other.

So i did some research through the AGCO website/google. Although the parts tag says its an ABO-22, later on it was called an MF 25 through massey ferguson. It appears as an "early production" MF-25. The upper bearing boxing does have an offset pair of bolts mounting it to the hanger. The "late production" does not have an offset pair of mounting bolts instead it uses a plate to offset from the hanger bracket to the upper bearing clamshell. The part number for the hanger is the same from the early to late production so what i think they did was change the bearing type from the offset mounting holes to the centered offset holes.

I'm going to try to clean up the whole bearing, piece it back together and try my best welding it back in one piece. Failing that i should be able to just replace the entire bearing and spool and fabricate a plate to shift the mounting holes from the hanger to the upper bearing box. I'm trying to not spend a bunch of money and use up a bunch of time trying to get the disk gang apart.
