The Travel Device, or final drive, is a crucial hydraulic and mechanical component of the Hitachi ZX350LC-7's undercarriage. It consists of a hydraulic motor (the travel motor) and a planetary gear reduction unit (the gearbox). The hydraulic motor converts the high-pressure fluid supplied by the hydraulic pump into rotational force. The gearbox then reduces the speed and multiplies the torque, which drives the sprocket and, consequently, the track. This combination ensures the excavator has the necessary power and control for moving across various terrains. Regular maintenance, including final drive oil changes, is essential for maximizing the lifespan of parts like YB60003036 and YB60003210.
Equipment: Construction Equipment - Caterpillar 345D Excavator
Fault: Excavator Boom Droop. The main boom of the Caterpillar 345D slowly sinks when held in a raised position, even with no load.
Solution: This is typically caused by internal leakage in the Boom Cylinder or the Main Control Valve.
Cylinder Leakage Check: Test for drift on both the lift and lower side. If the droop rate exceeds specification, the cylinder piston seals are likely compromised. Replace the seal kit on the Boom Cylinder.
Valve Spool Leakage Check: If cylinder seals are good, the leakage may be occurring around the spool in the Main Control Valve. Check the valve relief settings and inspect the valve for wear. A severe issue may require replacing or resealing the Control Valve spool assembly. For excavator valve control unit repair, consult an expert.
