Case CX130B Excavator – Parts, Specs

Description:

Serial Number Location:

For the Case CX130B (produced from the mid-2000s to early 2010s), the serial number plate is typically mounted on the front right side of the upper structure, just below the cab door or near the boom pivot. Always confirm the serial number when ordering parts—this helps differentiate between B-Series and early C-Series machines.

Common Issues & Fixes

Hydraulic Drifting: Caused by worn control valve seals or leaking cylinders—test circuit pressure and repack cylinders if needed.

Engine Overheating: Commonly from clogged coolers or faulty thermostat—clean radiator stack and test coolant flow.

Swing Motor Weakness: Check for internal leaks or clogged case drain filters—replace swing motor seals or clean system.

Travel Motor Noise or Vibration: Likely due to low final drive oil or planetary gear wear—inspect, drain, and rebuild as needed.

Joystick Lag or Creep: Usually related to low pilot pressure or faulty pilot control valve—bleed system and inspect spool action.

Electrical Fault Codes: Loose grounds and corrosion-prone connectors under the cab—clean and reseal harness connections.
