We have started on it just about to remove the track frame. Does anyone have the torque specs for the bolts on the pivot shaft?

Tighten the 9 bolts that secure the pivot shaft to the machine frame to 340 ± 40 lb ft.

What oil should be in the shaft? Looks like whoever had it before me replaced the oil with a lot of grease

For your climate SAE50 TO-4 oil, the same as what's used in the final drives. The original manual recommended TO-2 oil, but that specification has now been replaced by TO-4.
Don't you have an O&M Manual.? They come in pretty handy and aren't expensive, maybe $50 to download one from Cat.

Was thinking on this where Maye need do Both sides and make certain the bolting faces are as flat as possible.

I don't have a manual yet but I will be getting one soon. We ended up getting it put back together. Teardown to completion took us 3 hours so it went surprisingly well and everything looked good. I appreciate all of y'all's help.

It sure looks like the track frame has a crack in it in this picture. Just below the pivot pin.

Everything has been working good on it. Until I noticed a slight coolant leak, then I check it and find oil in the coolant. Not sure exactly where it's coming from, doesn't seem to loose any hydraulic, transmission or engine oil. I guess I'll be trying to figure this one out in the coming days.

Diesel??

That would have a distinctive fuel smell.
Leaking engine oil cooler maybe.?

Definitely not diesel. The smell is more oily but still has a strong coolant smell.

Looks like just the bolts are broken remove track frame take pivot off and remove broken bolts you can then check pivot for wear it is just 2 bushings and a seal
