is rock guards on the machine, if rock guards are missing, i have seen dozerstry to pop off track
A full set of rock guards on a dozer helps keep the track in place when its trying to climb off the bottom roller.In Parker05's situation it's not that uncommon for a track to try to climb on off a bottom roller in a bad spot where the track is off camber / twisting in motion and then the loud popping noise is the track falling back in place on the roller or sprocket.After a few hours in the seat you will be able to feel the track as it's trying to jump & correct it by steering left or right or approaching the task at a different position .Good luck with the TD7E.

rock guards go on the in side and out side to, that could be your problem or you might have a bad roller, it is best to have rock guards on.
Rock guards are called "track guides" as well, and go on both inside and outside. They are bolted to the track frame, and to each other with a spacer tube around the bolts (typically).
Looks like some models of the TD7 had the full rock guards. www.machinerytrader.com/listingsdetail/detail.aspx?OHID=9401363
You might get by with partial guards front & rear like on this model www.marketbook.ca/listingsdetail/detail.aspx?OHID=9459819&LP=MAT
With the full set of guards you can run in some pretty rough country with marginal undercarrige and not have any trouble with the track jumping the bottom rollers. My IH TD25 has the full guards and the rails & bushings are pretty rotten.No trouble with it climbing the bottom rollers .I think they help alot.Only drawback I see is its a pain removing the guards when replacing a roller.

We have taken off guards on our dozers and never had track derailment issues. Here in Kansas the gumbo dirt will collect in the guards and during the winter glue the rollers so they won't turn.
I would take a close look at the front idler roller and guides, if the idler bearings are out, or the guides the idler runs in are bad sloppy, the roller can wobble bad enough to derail the track.
Just something else to check before spending money. Good luck.

Also take a hard look at your track frames. Are they straight ? A bend or twist can cause your troubles.
