Nice progress. Good to see an old dozer coming back to life. I have a lead on an antique cat d7d made in 1959. Looks like it was abandoned in early 80s judging by the tree growth in the area where they were logging. It's sitting about 5 miles from my camp down an old logging road that was previously gated off due to an old landfill site that closed at the beginning of the road. There's also an old slasher nearby sitting abandoned.
Depending nohow well it is sealed up to water, you could get it going

Here is one for your memory bank, the radiator cap is missing. I will take a picture of the opening. It doesn't twist on, it bolts on with a center stud that sticks up and it looks like it seals on a flange. What confuses me is there is a overflow tube that is lower in the radiator neck than the sealing surface. The only way for that to work is if its not a pressurized system? You recall anything about that?Lookin' good!!
Start up is likely still a week or 2 away, still have to paint the pony gas tank after its de rusting and inspect the bottom of the main then oil everything. Got COVID so I'm moving a little slower.Wish I was closer as I have an old pair of crimping pliers with a section of the jaw for crimping those type of connectors. I'm anxious to hear how the startup goes!!
