Farmall M Narrow Front End

[scubasteve]

Can someone help me with what I am looking at on my Farmall M tricycle front end. I had a bearing issue and Have discovered that I have two different hub
assemblies and am not sure whether these parts are pressed in or if they can be removed easily. I don't want to re-install without cleaning the inside of the
hub assemblies. Also I have removed what looks to be seals and I think one set of bearings and seals is original and the other has been replaced before. Thanks
in advance.

Generally, outside races for tapered roller bearings (like your picture shows) are a light press fit. The seal behind that race is probably a light press fit also - I don't know this specific tractor. If there is access on the seal side, a collar of appropriate size should knock both out at once, with a press, or careful hammer work. No access on the seal side means a puller to hook the race out, and then the seal.

As far as the spindles are concerned, I don't know and can't tell if they are pressed into the carriers. Many are machined straight out of a forged casting. Some are machined as a spindle and pressed into the forged or cast carrier. If they are pressed into the carrier, it will take a hurky press to replace them out of the carrier, if the separate spindle is available - likely not!

Knock the bearing races out & get the numbers stamped into them.

The bearing should have numbers too.

Looks like the messy job I did yesterday, same thing too, one hub had all the original sheet metal dividers the other didnt.

I converted a 400 T post to 6 lug wheels to put on a 560.

To drive the outer races out, theres two notches in the hub so you can get a drift punch on it and drive them out. Chances are youll ruin the dividers. Its tough to find them with all the grease in there, but they are there. The seal wear surface may or may not come out with the race.

I did not reuse the sheet metal pieces, cleaned it all up and back together with new hubs it went.

The bearing kit for the M is stupid expensive compared to other IH tractors.
