Thanks Willie, I think the hard nose was laying to the side somewhere. He had the timing gear cover welded up. So this is a cat made thing? Are they rare? That loader is massive especially the arms. They weighed it and it weighs 20,000#. I should be able to take the weights off the back and mount a winch there couldn't I? John
Trackson suppled the loader for ealy Cats you bought it all together at the Cat dealer I beleave Cat bought them out as they did Russel, Barbergreen and others it weighs 18,000 complete . Not that rare some still is use today, most have trashed undercarraige from turning alot and grinding uo gravel while turning some had rippers some had counter weights on rear
