Friend has an International TD7E, (7 ton) I'll guess early 1980s vintage. They put new undercarriage a few years ago & it has had very little use since. The little it did see use was in the marble quarry. Crushed marble is corrosive. It has several stuck bushings, won't flex.
Tried heat, drilled the bushings hoping to get some oil in.
I'm afraid I don't fully understand how these are disassembled, & I certainly believe only the master link will come apart without a track press. I have my doubts this will come anyway rusted in as it is.
Does anyone have any wisdom?
My friend has a lot of experience with new track chains seized. His uncle had three dozers replaced them. For a number of years he ran them around enough to keep them free. By his death late eighties he had been unable a few years to exercise them. All were stuck! He freed them with penetrating oil & patience. That hasn't worked on this crawler.
