Not much detail to work with, I wouldn't guess. Is this an A or B? IIRC the B had power assist for the steering clutches, if it is manual operated it might be a 450A. .

If you click on the picture it will enlarge so you can get a better view of the undercarriage, I will put more pictures up asap.
Also, I just bought this machine and it will be shipped in the next week from Michigan. It is a 1968 450 no A or B just 450
it's one of the earlier models. The company I bought it from is very reliable and forthcoming on any problems the machine has.
I have done business w/ them in the past. I'm mainly trying to get an opinion of the undercarriage.

The pictures you posted do not expand for me. But you need to know about the pins and bushings anyway. I had a 450A like that in the late 1970s' did a lot of work with it, spent a lot on it rebuilding the steering clutches and new piston/liners. All of that transpired 35 to 40 years ago. Be prepared to play mechanic on one this old.

I'm having the same problem, can't tell much from those picts...
I didn't buy an old deere 450 because my dozer sometimes sits a while and old deere's have EXPENSIVE clutch problems when they sit around much...

Yes you are correct about the steering clutch brakes , I have owned a couple before this one, and I would block the the steering brake w/ a 2x4 across,
suppressing the steering arms, this would keep them from contacting with the flywheel.
This machine came from a local farmer who owned it for over 30 years before he traded it in to Buck & Knobby equipment sales.
I know one of the guys that works there, and have bought from them in the past, so when this one came in he contacted me. Yes it needs some TLC buy mechanically it is decent, the steering works well, has new rollers, and I figured the chain and sprockets appear to have about 40 + % left, at least in my opinion, that's why I was
interested in others opinion. Plus I only payed $3850.00 for it I figure the 6-way blade is worth half that much. Did you try and download the last pics. I put up ?

I would say it's going to need chains and sprockets very soon, yo have a decent amount of track sag and you are almost out of adjustments, also your sprockets look pretty worn and pointed, and the grousers are worn down pretty well also. If you plan on keeping it and rebuilding the undercarriage i would look into a salt undercarriage. The reason I say this is that I have a jd 350b that I completely rebuilt, and I bought new track assemblies . After I rebuilt the UC I didn't use it enough and I had a bunch of the track pins seize up with rust from sitting and having tight tolerances. I ended up having to take the tracks of and send them out to have them pressed apart and blasted, that was thousand dollars to have done. Also you will want to check the crossbars for wear. I was told by the service manager the worst thing you can do with an old dozer is let it set , he told me to get it out about every month and use for a while even if I don't have any work for it. It keeps the steering clutches and tracks from siezing up.

It has always been a dream to own one of those. I just don't think it will ever happen. I am just not ambitous enough nor have enough play money, not for the machine itself but for the inevitable repairs.
Too bad, so sad. I hope you have good luck and good fun with yours.
I find all the experience and comments on these cute little crawlers invaluable.
