Yes, 1960-1966 is what I'm seeing for the 977H.

It has lever steer and later H models came with pedal steer, so I'm guessing it's 1961, give or take a year. Still need to find the serial number.

This one needs an undercarriage, too, but that's way down on the list. If I could do it for $5,500, that would be awesome, but I think it's going to cost more than that. One sprocket has bolt-on segments, but the other doesn't.
We e had decent luck out of ITR undercarriages. It will be way over $5500! The 400g dozer is a SMALL dozer and it was outrageous. Pulling that one sprocket may be a bear. I think some required a puller, some were bolt on with a pilot. Good luck with the old iron. They are definitely worth saving!

Cat steel usually welds/builds up good. I don't have any luck with John Deere iron (under carriage) ..
Be sure to clamp ground directly to the sprocket, you don't want any arc(s) going through a bearing. A clean ground - no paint or rust is advisable.
I always liked the track broke and out of the way for better position.

Houston, we have a problem.

The bearing/hub assembly on the right final drive is damaged and will need to be replaced. I saw it before we started working on it, but I was hoping it wasn't a major ordeal to repair/replace. Now that I've done a bit of research, it looks to be a fairly involved and expensive project.

More to follow, but I think I know why it was free!!!

We used to do machining and welding for a guy who rebuilt CAT equipment. He’s still around. Let me know if we can help.

Can you please ask him if he has any spare parts for a 977H or D7 (977H has the same undercarriage as a D7 of the same vintage).

Thanks!

Latest video is up in case anyone is interested.

It seems really clean for an older machine. . If I could get it operational without going upside down, I'd do it. It's a really cool old machine.
