7. Field Failure Repair Cases
Case 1: JWS400 Connecting Rod Bearing Failure
Scenario: A JWS400 drilling pump experienced abnormal noise and reduced pumping efficiency due to worn connecting rod bearings (1714012), risking crankshaft damage.
Solution: Replacement of 72 sets of OEM-matching connecting rod bearings and re-lubrication of the power assembly restored smooth operation and full pumping torque.
Outcome: Pump resumed normal mud circulation within 3 hours, avoiding costly crankshaft replacement and drilling downtime.
Case 2: Inaccurate Mud Pressure Readings
Scenario: Faulty 0–3000 PSI pressure gauges (602-0085) provided erratic pressure readings, leading to over-pumping risks and inconsistent mud delivery.
Solution: Installation of calibrated replacement pressure gauges restored accurate pressure monitoring, allowing operators to maintain optimal mud pressure levels.
Outcome: Pump pressure stabilized, ensuring safe and efficient drilling mud circulation.
Case 3: Lubrication System Malfunction
Scenario: A clogged lubrication pump (KMS1OB02X1544SS) caused insufficient oil flow to the JWS400 pump’s crankshaft, leading to overheating and wear threats.
Solution: Replacement of the faulty lubrication pump and installation of a new filter element (DN381839) restored consistent lubrication.
Outcome: Crankshaft temperature normalized, extending the service life of power transmission components.
