Although the undercarriage is showing some wear there is plenty of life left. The real check is the stretched chain measurement as shown.
That blade bearing and trunnion is way overdue for replacement and has seen a lot of use. Those parts a readily available after market. Just need someone handy with torch and welder to replace. If you can get a part number off the links we can identify if the tracks have been up dated to 6.91" pitch from the original 6.75" or it should show with the correct stretched track measurement. I don't see anything else scarry there.
pretty much as Old Magnet says you can see the sprocket is down a bit and carrier rollers are a bit worn but I bet theres a lot of us who have a lot worse than that I would think
but as Old Magnet says all these parts are easy to come across and there is heaps of life left in the walking gear

Thanks for the responses. You guys are awesome as usual. Can anyone give me a ballpark $ estimate of worth?
The oil leak may not be a significant problem. The LONG 6 cylinder head on those tractors was noted for seeping oil and occasionally coolant out along the head gasket. I think that head was about the longest one CAT ever designed. All the larger engines had multiple smaller heads.
Anyway, lots of them have an oily mess down the side of the engine.
Looks like a nice old dozer. Have you run it?
Pony motors are frequent cause of baldness or Grey hair!! A good one is very nice. I didn't notice if that one is direct electric start or pony. Late serial number, so could very well be electric start.
Here is my latest purchase, maybe it means I got screwed or not. Late 50's D8-14A (I'll get some pics up at some point). It is air force badged, converted to electric start and alternator system. The drivetrain is excellent, tracks rollers pins bearings gears all have light wear. It fires right up and operates as it should. It has a winch on the back that does not work. It came with new batteries (2 of those big D4 batts are not cheap). It also came with a clearing blade (that was fun moving that).
I paid $10,000 for everything plus $1700 shipping from Yakima WA to Portand OR.
Of course I would have rather had a hydraulic Cat but the price goes up substantially and I couldn't afford more, plus what was out there was not in as good condition. This will do the job I need done.
If she runs good and everything works as it should I'd say the $7 to $7.5K that Ray54 mentions is about right. That late a s/n has the added bonus of provision for direct electric start (I can see the cover plate for the starter hole) in one of the pictures.
These are still good ole tractors that can produce plenty of work and are the least complicated to maintain.
Hey Raklet,
I bought a 1960 D6-b cable dozer recently in Northern California. Paid $5500 for it. Those tracks have welded add on grouser bars. It's just an indicator that they have been worn down and built back up. The trunion balls on mine were shot as that one. I welded new ones on. It's a nice dozer now. Good luck.

If I were selling it I'd be starting above that $7K price and not let it go for anything less. I really like My D6 9U a lot.
