I'm not sure if it was the cold weather, or if it was bound up by dirt or just stuck because it hadn't had grease pumped into it in a long time. I ran it and attempted to pump the grease in it a couple times a day for a couple days. Each time it seemed to take just a little bit. Then next weekend that I went up there, after sorting out my alternator problem, it got warm. I ran the excavator for about an hour then stopped and put some grease in and it took the grease, no problem. And it held the tension fine.
