    Noticed an issue on my Case CX490D machine today. Seen one of the track pads was sitting kinda crooked, then realized it was because one of the track pins has been working its way out. What typically causes this? Just a sign that the undercarriage is worn? Any tips for getting it back in or the correct way to fix this?? Thanks!!

    Loosen the track and run it about half way around on the sprocket and put in a new master pin.

    It's the only one that you can pound out with a sledge hammer. The rest you need a big track press.

    I can't see the rest of your tracks so don't know.
    But on well worn tracks that some times happens usually after the pin is improperly installed.
    What do the other end of the pin look like?

    Looks like the rails are getting towards the end. You can always just weld around the ends after you get it back in place.

    That appears to have been subject to bad installation practice, best to replace with expander pin if you can find a supplier.
    Kind regards

    Do we think this actually is the master pin?

    Look at the rest of the pins and see if any are different.
    How about a picture of the idlers on both sides?

    It probably doesn't help that the track is installed backwards on the machine. The burn marks on the rails also mean your chain is riding hard on some piece of the frame or maybe a frozen bottom roller.

    Could you explain more about the track being backwards? How could you tell?

    Looks like the other is too, if you don't travel a lot won't make a lot of difference at this point.
    How about pictures of both front idlers?

    One of your photos show a sprocket which is at the back of the track frame. The big ends of the links are looking back at the sprocket and should be looking forward at the idler instead.

    Only the master will clear the bushing ends, are two large washers taking up the spaces in the master link end.

    Looks like you have pins working out on both sides. Judging from where the idlers are and the condition of the links, I'll guess that someone cut a link out of each side to make the chains run longer. The last photo shows the correct direction of the chains.

    If were OE rails at around 4000-5000 hours depending on materials aggressive qualities they were worn to limits.
