I have a 311B Excavator when cold will allows me to turn the tracks but as it gets progressively warmer I lose the ability to turn and only allows me to travel forward and backward. Changed the filters and the oil. Anyone have experience with this type of issue? Would like a direction prior to me tearing into this thing whether it be a pump or seals. Otherwise, machine says everything is fine.
The machine Serial number helps to locate technical information. A service manual might also help you to understand the drive system and how to test it. Again needs a Serial Number to identify the appropriate one. What oil did you put in the system.?
