Big compressor, 1/2"++ airline, 1" impact and a deep checkbook...
Other than that it's basically just ****** work.
The idlers can probably be refurbed by radius welding and reseal/repacking.
Bottom rollers are probably best replaced. Sprockets replaced unless they're segmented.
The chains can be addressed by a bushing turn (if it hasn't been done already) and the rails are not worn down too bad.
The pads can be rebuilt by welding new grouser bar on. You can buy grouser bar from a dealer or probably Berco, cut it to length and weld it on.
That said, it's time consuming unless you've got a big welder and big rod. It might be just as economical to replace the pads if the pad itself is getting thin...
Other than that, a loader or engine crane is handy for lifting stuff and a comealong to help join the chain when you're done. Basically it's just hard, heavy work.

As with many things there are often several right answers and a few wrong ones. Some purist I'm sure will disagree to no end with what I will tell you but most of us out here in the real world don't really care do we ? Some of them only bring their noses down out of the air long enough to look down them anyway. If you are like me you are only doing this old tractor stuff because you enjoy it. You ...
