1958 D6 dozer engine?

Hdonly · Dec 15, 2018

Brought this Caterpillar D6 dozer home today. Trying to identify it for sure. I was thinking that a 1958 D6 should have a D318 engine. I don't think this is a D318. Has oil clutch. Had pony motor but now is direct electric start. Thoughts?

Should be on tag on pic .

if I remember right, 318 is embossed below the radiator surrounded by a block shape. About 3 inches by 3 inches. My Cat road grader had the same engine.

Wouldn't that be easy except that tag is hard to read. Kinda looks like: 44A243?? Can't tell for sure though. Anyone know where I can find a chart of engine numbers? So far, I haven't had much luck finding numbers that seem to match. I bought it as a 1958 D6 that should have the D318 enginge. All the pictures I see of a D6 with D318 engine, the engine is not the same as this one. Maybe this is not a 1958 tractor? I have not been able to find the tractor numbers. I read that they should be behind the winch. That will be tough to see without removing the winch.

Thank you so much for that information. Seller claimed it was a 1958, not that it makes any difference. I would have bought it anyway. Everything works on it. Engine runs good with very little smoke after warm up. Undercarriage not in the best of shape, but will do for my needs. Blade works good, brakes good, steering good, clutch good. One track adjuster has been welded. I am going to fix that. All rollers spin and look to be in good shape. The rear cable winch is stuck, but it looks like the ferrule on the cable has just been pulled in to far. It is wedge in, but I'm sure I can fee it up. Paid $4500 for it and have already had two people want to buy it from me. Not for sale, yet anyway-haha

You can add me to the ones that would like to buy it.
I been looking for a cable D6 for a good long time.
Nice looking machine. I am happy for you, and jealous all the same. LOL..

You may already know if you are familiar with those machines,that second winch is not a drag winch.It is a tool winch,meant to pick up things like scraper pans.It is not meant to pull things out or up.It runs at a much different speed than a drag winch.If used for the wrong purpose they can self destruct pretty fast.The best part about them is the real expensive,wearing parts on the blade winch are in that side too.I had a D-6 9-U series with that same winch.Fortunately I was warned before I did something stupid with it.I was just about to do just that.Mine came from a fire department,who had gotten it through the Civil Defense.I think they are a nice nuts and bolts machine,and easy to work on.

Yes a D6B with the D333 engine,pity the grouser weren't built up before the shoes bent,what are the chains like,good dozer those,my choice would be a hydraulic blade with a tilt.
Good luck

Got the left winch cable loose today. Took a while as the ferrule on the cable had been pulled in so tight, it was stuck hard. Finally hooked my little Ford 651 to it and gently bumped it about a dozen times. Finally, out it came. I pulled the cable all the way out and then used the winch to pull the 651 back.Did that about three times and everything works like new! Started cleaning all the crud off and making a list of loose, missing and broken bolts. There are a few. Started checking fluids, grease and such. Also, sold a goat for $50. It was a good day.

Drove one like that for a few months in the late 1950s, when I was much younger (and maybe not as cautious) clearing land.

Here the winches on the back were called a double drum power control unit. It could control a cable blade or a scraper. Hydraulics were not common on
these machines at the time, especially when the dozer was used for land clearing as sticks tended to wipe out hydraulic hoses.

Now that I know the left side works, it will just be unused. I'll consider it "parts on the shelf" in case the blade side goes down. Got to keep the blade working.

Tag you have there is the engine serial number. The tractor tag should be down on the rear left side top of rearend case. That is where Ours are at . D-4 with 4G8 and No.6 traxcavator 10A1 The Traxcavator is a D-6 with a loader on it all hydraulic.

Those grousers can be built up with some 1/2inch flat stock about an inch wide welded to the top of what is left of the original grousers. Don't be afraid to put the heat to it welding them on.

This is a Cable Control Unit, (CCU) the line speed is designed for cable operated attachments, one side is dedicated to your dozer blade, the other would be used for tow behind, cable operated equipment such as a scraper. In that case, both spools would be used, one for the apron, the other to lift or lower the bowl while in a cut. Reason I mention it is that the line speed is a lot faster than a towing winch and these are not designed for towing although someone did put a hook on the 2nd line. You would notice something if you tried to winch out something heavy, going to slip and you may get the friction linings hot from slippage.

Hdonly · Dec 30, 2018

Not planning on doing any winching with it. I will just leave that side alone and use parts if needed for the blade control side. No sense in tearing it up. If I can't push a stump out of the ground with the blade, I have a small backhoe I can dig it up with. Use the right tool for the job.
