A scored boom cylinder piston rod and a seized pump servo piston caused internal oil bypass and uncontrollable hydraulic oscillation
A cracked air cleaner housing allowed unfiltered dust to seize the turbo wastegate, causing extreme engine under-boost and lean backfiring under load
A worn torque converter lock-up valve and a degraded transmission filter bypass spring caused delayed clutch fill and oil thermal breakdown
A failed swing motor mechanical brake relief valve caused clutch disc glazing and metal debris contamination, preventing braking force
A seized lift cylinder counterbalance valve caused continuous high-load pump motor operation, triggering current limits and burning armature brushes
A worn steering cylinder cushion valve and water-contaminated hydraulic fluid caused the Orbitrol rotor to resonate violently at high speed
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
