carrier wheels and tracks

[Lynn Eades]

These things go in circles. This has been discussed before. I would break them up now into manageable sections, ans soak them in oil for a few weeks. Then I would try to get each link moving, using a couple of suitable pry bars. I would then leave them to drain, and dry out before fitting. I used waste hydraulic oil, but imagine used auto trans oil would be good.
This has probably kicked off another round of "track abuse" including beating, burning, blasting, dragging etc. You could have just towed those dollies about 20 miles, with a load of power poles on it. if they went around without breaking the pins, they would have eventually come right.
I can, from experience, tell you that when they are really bad, you can use a lot of gas, and time, trying to salvage every second link. Have fun.
