CX300C and CX350C: owner reports

Sources: 3 forum discussions about the Case CX350 excavators (CX350B); heavyequipmentforums.com and tractorbynet.com.
  • CAN fault, fuel filter air and an engine stop message. A CX350B whose monitor showed nothing and an active CAN communication fault (a reply listed arc welding, lightning, striking a power line and jump starting as things known to damage controllers), a CX350 whose clear-bowl first fuel filter kept emptying, and a CX350 that shut down and would crank but not start with an engine-stop message. Threads read: 1, 2, 3.
