I am new here....please help me with this wheel /sprocket

[unknownitembuyerhelpme]

Thank you for looking at this for me, any info to do with this caterpillar track wheel / machine sprocket would be very handy. I know nothing about it : (

DIMENSIONS :
Tooth to tooth / Largest diameter approx. 45.7cm (18") Inches
Thickness 3.2cm (1 1/4")
Axle/shaft diameter 3.8cm (1 1/2")
A solid plain bearing is fitted, not solid metal but some type of really regular tiny holed (visible only using my magnifying glass loupe) multilayered fibrous resin type material used. It has broken up in places away from the metal diameter it is fitted to.

Centre boss outer diameter 9cm (3 1/2")
Please take into account some loss of material due to corrosion.

Please see the photos and many thanks again (a lighter is placed at the base of photo 1)
Kind regards, Jon.

Are you sure it's off a Caterpillar? looks more like a bed chain sprocket from a muck spreader or similar.

THANK YOU for your reply. At last I am getting somewhere : )
I bought this item on Ebay as a ww2 road wheel from a ww2 tracked vehicle supposedly from the Breslau campaign Poland 1945.
I have previously submitted the photos to a military forum and they can't identify any exact vehicle link for this part. Many people mentioned agriculture, so that is why I started this thread here.
Getting nowhere and receiving a full refund shows how little the seller valued it. I will now buy a Tractor seat and make it into a COOL bar stool to make up for all the waste of my time.

Any other ideas or exact info anyone ?
I will appreciate any further effort : ) let me know / show me photos !

When I was a youngster, we had a lime/super spreader that was mounted on the back of the tractor, it involved unbolting a dual wheel and bolting on a frame with a driving sprocket to the inside wheel. That sprocket looks a spitting image of what the driven sprockets looked like, from memory it had a stack of 4 to change the rate. Each one had an extra tooth, so rate was governed by land speed.
Wouldnt have a clue as to the maker but I can remember undoing the chain and putting all the links in a kerosene tin! And then an hour into the lime store for a refill on a SAME Corsaro 70 with cotton wool in the ears.

Cool Kiwi Pete, Many thanks !
The internet brings us all together with ease again.
Great reply ! Jon
Anyone else wanna join in with a make or model ? Ta !!

 

[Muck Spreader]

The only tracked thing that would have a sprocket that small and crude would be something like a Goliath, but I am sure you will have already looked at that on the military sites.

 

[unknownitembuyerhelpme]

Thanks Muck Spreader.........

'We' have eliminated that option on a Military forum as those shoulders on the teeth are not there / needed on examples of the Goliath remote control bomb that we see on the net/Google images. I wish it was a Goliath drive wheel as it would be literally worth a bomb !!
Kiwi Pete states above in his contribution to this thread in relation to a Muck spreader assembly...............

Thanks again for the thought !!

I wouldd have thought it could very easily come from a half track machine or an artillery piece probably Russian being very crude. The absence of a proper bearing would be accounted for by the lack of Ball bearing machining capacity.

Third photo looks like you have a serial no location on the left hand side. With the narrow lugs and wide gaps I would have suggested a drive chain sprocket for some sort of elevator.

Thank you, I seem to be getting more sense from this Farming forum than the Military forum I have been using !!
The bearing that is left in the axle bore is some kind of plain bearing surface several millimetres thick. Under my Loupe / small magnifying device there seems to be radial layers overall and there are very regular perfectly round tiny holes looking down at the bore top. I know that lignum vitae hardwood is self lubricating or can be oiled and the relatively slow rotational forces of an axle take a long period to cause wear to the wooden plain bearing. I can't explain the very regular identical diameter holes seen in the bearing material when looking down at the diameter of the bore.

A possible is that the plain bearing could be a cage of very thin metal, say bronze, which has loads of regular tiny holes that is then pressed into the lignum vitae wood body. Lignum vitae wood that pokes through all those tiny holes in the bronze cage and touches the axle is self lubricated PLUS oil is also added to protect the axle from the bronze cage.

Do you see what I mean ! They invented another type of durable plain bearing when they had a shortage of ball bearings.
I definately subscribe to the crude sprocket Russian vehicle theory, WE just need THAT photo to prove it : (

 

[Exfarmer]

to be honest there are so many different things this could be off, anywhere a non roller chain has to pass over , it could be from steering gear to ranging gear or a host of appliances military, agricultural etc.
I think you will be extremely lucky to identify it.

 

[unknownitembuyerhelpme]

Yeah, well this was a last chance !
It is now going to be the base for a tractor seat bar stool , so it is going to get modified a little anyway : )

 

[Mursal]

Any harm asking how much you gave for it ..........

 

[unknownitembuyerhelpme]

FREE now refunded due to not being what the seller and I thought it was / unknown and a given that we will never know : (
FREE to do with whatever I choose, in the skip or use, for something !!
