A corroded swing bearing gear and failed slew motor brake caused the machine to overspeed and trigger false load warnings
A failed torque converter lock-up clutch and clogged transmission filter caused severe heat generation and loss of drive power
Corroded hoist contactor tips and a frayed battery cable caused severe voltage drop and controller lockouts during heavy lifts
A blown travel motor balancing valve and worn reduction gear bearings caused unilateral power loss and severe track misalignment
A failing fuel pressure sensor and restricted pickup tube caused false ECM derates and sudden stalling under load
Internal leakage in the steer cylinder and a bent steer axle pivot caused dangerous alignment drift and rapid tire destruction
A varnished boom holding valve poppet and blocked pilot orifice caused a dangerous 2-second hang followed by an uncontrolled fall
A split charge air cooler core and blocked turbo wastegate caused severe intake starvation and high exhaust temperatures under load
A seized drive motor bearing and a worn steering potentiometer caused excessive amp draw and erratic controller faults
A water-contaminated swing reduction gear and a seized brake solenoid caused violent rotational stuttering and rapid gear wear
