Welcome to the forum jms. I read your intro post in the new member section. Sounds like your at an interesting cross roads and have plenty of work to keep a loader busy!
Our undercarriage is a mixed bag. I don't have any percentage numbers for you and I probably won't be using the correct terms for some of this, bear with me. The track shoes are excellent, good height on all the grousers. The sprockets are decent. For what we've done and have left to do the sprockets have plenty of life left in them. One of the idlers is like new. It must have been replaced in the past. The other idler guide bar is rounded off a little, but it's in decent shape. The rollers are worn pretty bad. They're cupped from the chains. The chains are the worst. They're worn down to the point the pin bosses are hitting the bottom rollers. BUT, we go slow and have traveled quite a bit in the 300 hours on the machine and the undercarriage doesn't show any more signs of wear from when we bought it and we've gotten a lot of work out of it.
I'd be interested in seeing the pictures you took of the 175. There's a thread in the support forum on how to post pictures. Good luck and keep us posted.
