These were for sale 2 blocks from me. Reasonable price, less than 25 cents a pound. I believe he said they were tractor sprockets, whatever those are.

They are big, over 36" diameter and nowhere thinner than 2" thick, and weigh over 250 pounds each.

Now that they're here, I have NO IDEA what to do with them.

But I had to have them.

Track driving wheels? (Off a Caterpillar, to judge by the colour.) They'll be interesting to work on.

If you could identify just what they fit you might be able to sell them for a nice profit and buy material in more useful sizes. They look new as far as I can tell from your pic so would be of interest to someone refurbishing an older machine.

Yep, track sprockets. Worn too. I always thought I wanted a bulldozer until I had to operate one with worn out sprockets and rails (the chain that the sprocket and rollers run on and the plates bolt to) If you ever run a dozer out of the tracks and spend a couple of hours with a pry bar and come along and a lot of sweat, you may rethink your aspirations. Even worse, out of both tracks while half loaded on a lowboy trailer. My dad had something to say about that one...
Also, having an old bulldozer gets old if you break a track link on the jobsite and try welding it back together because replacements are unavailable in the state or surrounding states.

They look like they came from an excavator to me. Might be a cat number one number one letter 4 numbers (1x1111) that would help find out what they fit.

Now you just need to buy a lathe that can turn them down.

They look worn to me as well. I refurbished a set on a small excavator years ago. I was able to order hardened half circle cups that fir tightly into the sprocket and returned it to it's proper pitch and diameter. Just run a hot bead around the perimeter of each half-round, both sides and a bead between each other and done. I didn't even take off the sprocket. It went back to work and used it for many years. Couldn't believe how easy it was and inexpensive. Never threw a track after that.

I agree with Wes. My job for many summers and weekends entailed replacing tracks small crawlers.
The worst was in a large creek at night with it trying to snow. He was not supposed to be in the creek with the tractor and wanted it out before anyone noticed.
I had to do another on a pile of Pea Silage. It stunk so bad that when I got home I stripped to my shorts outside and put the clothes in a washtub before going inside for a shower.

I know a guy that just sold his entire new old (and I mean OLD) stock inventory of International and Cat crawler parts for 50 cents a lb. Brand new sprockets, track pads, track links, turning brake clutches, bronze bushings you could stick your arm through. Well over 25,000 lbs IIRC.

Tractor weights. You can double your $$ easily if you find someone with a small tractor that just fitted a loader. ;-)

I'll give you 6 months to scratch build a bulldozer around them.

Sandblast then paint. Cover with a piece of tempered glass.

Stick 3 legs on it, cut a pointer thing (it has a proper name I can't remember) and make a cat D8 sundial for the garden, well you did ask for suggestions and you aren't going to be machining them any time soon!

Use them as the rear wheels for that small tractor you've been meaning to build. Those teeth should give you pretty good traction.:rolleyes:

Worn out? Darn, I would have sworn there was paint on the inside of the teeth.

That is a good starting point to build a doozer! Just keep scrounging parts till you get the whole doozer. Are there any numbers on the sprockets?

They will make a great heavy stable base for a-something.

Consider adding 3 x small (say 75mm or 100mm) wheels; one swivelling, two fixed. These could be under the bases; or if you got creative, set into holes cut into (and near) edge of the base.

Sharpen the teeth, harden and temper, then make a mandrel to mount it in your mill as a shop-made cutter. I read about doing that in a book once,

Sometimes he gets together with Arnold, and they prank their friends by flipping their house upside down.
