Hello, I am new to the forum. I am finally bringing home a D6C after much contemplating and searching. The serial number is 10K5064....? See picture.
[attachment=36676]20170719140932-492bfd30-me.jpg[/attachment]
It is has the non turbo motor which I am guessing is the D333. I also has the powershift transmission. The previous owner told me he thought it was a 1974 but from the research I have done I guess it to be a 1970 year model. The past 7 years it has been working in the woods clearing hill sides in Northern Arkansas. From the test drive it seems to run well and doesn't need anything in particular that I can tell besides new tow steel and the track pins turned. I plan to order toe steel from Dura-Tuff and my brother and I are going to weld them on. I do not know of anyone local that turns track pins. The previous owner thought I would have to take the tracks to Oklahoma if I wanted the pins turned and he suggested just buying new chains.
I plan to use this dozer on the farm to clear off some pasture land and whatever else it will come in handy for. The dozer should be at my house by Sunday so I will be able to work it alittle after that and see how it does. I need to get a service manual for it and I want to go ahead and change atleast the engine oil and filters to start with.
I have joined the forum here to glean information from you guys and to have a place to keep track of the time I spend with this Cat. I plan to have it a long time, good lord willing. Enough talk here are a few pictures:

Would love to hear what you guys think of her and any suggestions for a new owner are welcome and appreciated. Thanks.

Hello, Welcome to the forum. Looks like you have a pretty straight tractor there. Pretty much if a d6c is running and driving it will be good for the farm for a long time. Others can attest that the d6c is one of the best tractors that Cat made and may be the most reliable. they will run with a multitude of things wrong with them. Anymore, it's only a few hundred dollars more to buy new chains than to have the bushings turned. A set of Korean chains would last you a few thousand hours and on the farm that might be 20 years. They are a quick machine and you can move a lot of material in an hour. If you don't need the side screens on the farm I will pay you whatever you want for them. I use mine for building logging roads and too much trash get in the engine compartment.

That's a 1971 machine, 125 hp with D333c engine non-turbo. Looks to be a pretty straight machine.

Hi, Rustybottoms88.
That is a neat looking machine. Congratulations and welkum too ther 4um.

I have just one suggestion - if you plan on using that tree pusher for any serious tree pushing, I would suggest that you wind the tilt braces on the angle blade pretty much right back in, certainly at least until you reach the end of the threads, to avoid bending the threads.

Otherwise, gopheritt.

Just my 0.0.2

You have a wonderful day. Best wishes. Deas Plant.

You can't wind both tilt braces back on an angling blade since they are designed for tipping the blade from side to side, not backwards and forwards.
The blade cutting edges need turning, not changing, and new corner shoes.

Hi, Catsilver.
With all due respect, I would suggest that with a machine of that age, there would be a fair bit of wear in the center pivot pin of that blade that WOULD allow some substantial winding in of those tilt braces. I do stand to be corrected but only by the current owner. I would also suggest that winding them both back to where the blade was level with both close to tight would help to stop the blade tilting itself from side to side due to wear.

Just my 0.02.

You have a wonderful day. Best wishes. Deas Plant.

I stand by what I said Deas, those braces are not designed to tilt the blade back, movement will be limited and only allowed by wear.

Hi, Catsilver.
You can stand by what you said and I will stand by what I said. See your last 3 words. And just in case you are in any doubt, I have had a little bit to do with angling blades with tilt braces in the past - beginning in 1965 - so I do have some idea of how they wear. With SIX wear points each side plus the center pivot pin, there is no small scope for wear.

Thanks, I am pretty proud of it. I looked around for along time before I found this one. I had searched in several states and then this one ended up being just 20 miles down the road and has all the things I was looking for: sweeps, screens, powershift, angle blade and a tree pusher. Thats good to know about the chains, I will certainly consider just buying new. I will post some pictures of the undercarriage once I get it home. I will be in the woods with it quite a bit so I plan to keep the screeens, however if I decide to part with them I will let you know.


Thank you for the information. That is a big help.

Good eye! I had forgotten to mention the cutting edges on the blade are wore. I didn't notice any excessive wear in the pivot pin but its been several weeks since I checked it out. I am sure once I get it home and start using it I will find some wore pieces here and there.
