Our cat E-120B excavator travels fine when it first starts, turns good, pulls good, quiet..everything seems great, after its run a while it seems like the brakes are dragging, can't turn, every bump stops it.. sometimes you have to rock it back and forward a little to get it to move, and it seems to make a screeching sound when it moves..when it does travel it will suddenly break free and travel real fast then down shift to low range ( its always in low range on the switch) then it seems to bind up again.. HELP.. ANY IDEAS?? cat dealer was no help..they say its a grey iron machine, not ment to be sold in north america..BULL.. this is same dealer that sold the machine!! seems like it is shifting between high-low-and brakes slightly set is this possible?
