Removing stuck clutch hub on John Deere LF spreader?

[Mountain_anderson]

Hi all
I just got a John Deere LF spreader and the hub on the right side is completely seized up and I was wondering how I remove it to rebuild it? I already removed the wheel and clutch side but I am not sure how to access the the clutch part and how to remove it, furthermore, rebuild it. Anyone have any ideas?

Heat....

But how is it removed? Its not the fact that its stuck and I can't remove it, I just don't see any bolts or nuts or anything that need to be undone except pounding the hub out but I prefer not to do that if thats wrong so I don't risk mushrooming it

I know nothing about this spreader, but found this. Zooming in may help.

If you follow the JD parts link, you can scroll back a few pages to "Feed Shaft". It shows the parts breakdown, and attachment to the feed shaft. IMHO, I'd apply abundant amounts of your favorite penetrating oil and try to separate the parts without too much hammer application. You're probably going to want to check/lube the wheel clutch assembly, as well.

I have a 10 ton hydraulic puller from harbor freight but a lot of times when I use it with old cast iron parts is it just breaks them even if I do apply penetrating fluid. How can I lessen this risk?

I wouldn't go yanking on it with a 10 to puller either. There's got to be some retainer holding it on, a pin, or a clip of some sort.

It appears from viewing parts schematics that there are 2 square keys(item 9) AKA button head rivet that will make rusted hub difficult to remove from axle.

Here's a couple of pages from the manual showing service procedures. The parts Tx Jim lists are on the clutch assembly, outboard of the wheel, included in #3 in the manual pics. The parts you are trying to remove are located inside the spreader box, indicated by #4 in the pics. Note that there are 4 individual parts that are rusted between the socket drive and the spreader box sidewall.

The hub on the inside of the wheel is ratcheting grease and is all grease up, it is actually the hub on the inside of the hopper box which is seized

That almost looks like one of those old pinch washers that they used to use to hold things on. I would take it off by looking for a split that could be opened, then with your puller snug it up and then put the heat to it. Then just tighten it up a bit not to much and see if it moves if so continue on some more. IF not let cool and then reheat with puller snug again might even need to do this a few times. Each time the cooling and heating lets it creep slightly with the cooling as it is tight and has to move infinite amounts. Some squirrel pea might also help with each cooling. I prefer fuel oil like diesel it will creep into any crevice given some time. this is not going to be a lickity split job.
