A stuck main pump regulator cut-off valve and the use of incorrect high-viscosity hydraulic oil caused flow starvation and erratic cylinder movement
A seized steer knuckle thrust bearing and a misaligned torque sensor caused continuous high-current draw and thermal protection trips in the EPS motor
A broken torque converter stator blade and a seized modulation valve in the valve body caused severe impact during gear engagement and loss of hydraulic power
Pitting corrosion on the swing bearing internal gear and a stuck-open relief valve in the swing motor caused loss of swing brake holding power
Severe oil overfill causing liquid oil ingestion into the intake manifold, combined with a seized fuel shut-off solenoid, resulted in a runaway diesel condition
A blocked transmission oil cooler and worn torque converter stator splines caused lubrication starvation and clutch slippage
Broken swing bearing bolts and a clogged auto-lube distribution block caused severe ring gear wear and chassis rocking
A clogged turbocharger oil drain line and a failed PCV valve caused crankcase over-pressurization and forced oil past the turbine seals
A seized torque converter stator one-way clutch caused extreme drag at low speed, lowering engine stall speed and preventing heavy loading
A failed pilot pump needle bearing allowed metal debris to jam the main pump regulator, causing continuous maximum displacement and oil burning
