I have some more stuff I am trying to clean up.

Does anyone know what this is? Some kind of farm equipment I'm sure.
Do you know how to get it apart?
I can back the axle nut off but can't get the wheel off or the bolt out.
I have only used WD-40. I did try to press the bolt out with a 12 ton press as tight as I could press it. I even put my foot on the press handle. I let it sit over night under full pressure but it won't budge.
I tried driving a wedge behind the spiked wheel and that won't work either.
I'm stumped.







I have three of these in different sizes. It is a roller cone drill bit for oilfield drilling.
I'm trying to clean up the smallest one but can't make the grinding wheels spin so there are places I can't reach.
Once again, I have only used WD-40. I clamp the thing in my big blacksmith's vise and try to turn the wheel with a big pipe wrench. No good!

I have no idea how this thing goes together. The bits must be pressed in somehow and they surely are sealed so I'm not sure the WD-40 is doing anything.
The small one weighs about 10 lbs. and the biggest is about 60 lbs.

None of the three turn. The wheels should spin independently of each other. They don't work like a gear.
Any ideas?

ZULU: I KNOW ABSOLUTELY NOTHING ABOUT METAL WORKING! That said, would battery charger electrolysis do anything to help with either the rust or breaking parts free. Also, what about some kind of air hammer with a high beat rate to bang on parts as other pressure is applied such as heat or hydraulics. Another thought, even though it is not constructive. Those items were discarded for some reason by someone familiar with how they should work. Although a challenge is exciting and rewarding on completion, frustration enters into a picture at some point and scrap value can buy some more WD 40 for the next project in line.
Just some random thoughts from someone with a low threshold in patience

I have one suggestion.
Try heat.
Use a torch to warm up the outer part around the axle to see if it might expand a bit. (Don't make it "cherry red" or you'll weld it together) Despite what some people think, the hub will expand not shrink.
Also the air hammer with a hammer bit in it might vibrate things loose while it is warm. By warm I mean too hot to touch but not "red hot" as I said before.

I have seen that first picture some where. I think it is part of a planter or weeder. Memory is not good anymore.

I believe I will try some Kroil penetrating oil and maybe some heat.
We will see how it works.

I've never worked a farm before so know little about the machinery used there.
However, is it possible that the nut on the spider-wheel-thingie is reverse threaded to keep the nut from backing off during use?

In either case ... heat and/or Kroil should do the trick ... eventually.

You come up with the coolest stuff!

I've got the nut free. I can't get the spider-wheel-thingy off.

Zulu,
The first pictures are of a rotary hoe. They are mounted so the the curve of the spikes point forward at the top. The spikes enter the ground on a downward angle and come out of the ground on an upward angle, lifting the soil and any small weeds. the faster the ground speed the better it will work. Only very effective if soil conditions are right and the weeds a quite small.
Some things are assembled by what is called heat shrink. The outer part is installed very hot and will not come off until that process is reversed. As others have suggested, try heat. Some times heating and then letting it cool completely will break the joint loose. Been my experience that hammers tend to break things
Don't know "nothing" about oil well drilling. Heating the whole thing up might help.
The comment I made on a prior thread was not intended to be negative. Just amazed by what comes up on off topic. I love this forum and especially the Scrap Pile. It is the first place I go to when I get on line.

Thanks Norm,
I coated the rotary hoe with some Liquid Wrench penetrating oil earlier today.
This afternoon I messed with it a little.
I tried to turn one of the spidery things and to my surprise, it turned.
That's when I found out it was theaded on the bolt. Who would have ever thought that?

It turned off and with one slight hit of a hammer the bolt came out. The other spider is not threaded so it just came off the bolt too.

Threaded! No wonder 12 tons of pressure wouldn't push it out.

Now. I'll figure out what to do with it. I have three of those things. A second one is soaking now.
