A plugged hydraulic tank breather and worn main pump swash plate caused vacuum suction and engine overloading
A loose priority valve mounting bolt and scored steering cylinder rod caused pressure drops and hydraulic oil leakage
A stuck priority valve and air in the steering cylinder caused the steering to go hard randomly during sharp turns
A worn swing motor bearing and restricted pilot filter caused cavitation and insufficient rotation torque
A sheared parking brake cam shaft and collapsed torque converter bearing caused the transmission to lock in neutral
Misaligned mast rails and stretched lift chains caused roller binding and uneven fork height, requiring full mechanical re-alignment
A leaking pilot pump coupler and worn load check valve seat caused simultaneous pilot pressure drop and hydraulic cylinder bypass
A sheared stator support spline and clogged torque converter filter caused complete transmission power loss and overheating
A shorted steering angle sensor and corroded high-voltage connector caused simultaneous safety lockout and steering failure
A broken brake piston return spring and air ingress in the pilot line caused the swing parking brake to drag and overheat
