A kinked boom pilot hose and blocked tank breather caused main pump starvation and erratic valve spool movement
A failed track adjuster seal and a broken final drive planet gear caused track misalignment and driveline binding
A melted Diesel Particulate Filter (DPF) core and seized wastegate lever caused the engine to choke and lose power
A broken return filter element and debris-clogged boom float spool caused uncommanded boom descent and hydraulic thermal runaway
A blocked regeneration orifice in the bucket control valve and a worn pilot pump caused hydraulic starvation under load
Corroded traction motor phase connections and a degraded battery cable caused voltage sag and inverter cut-outs
A cracked hydraulic tank baffle and torn suction strainer caused pump cavitation and slow implement response
A failed planetary gear bearing in the swing drive caused metal debris to destroy the output shaft seal
Welded lowering contactor contacts and a burnt dynamic braking resistor caused the hydraulic pump motor to seize in the “Lower” position
Water contamination in the shift lever sensor and a damaged wiring harness caused intermittent transmission disengagement
