A worn brake piston seal and contaminated hydraulic oil prevented the swing brake from holding the machine on slopes
A stuck brake piston and blocked vent hole caused brake failure and differential overheating
Worn brush holder springs and a blocked traction motor ventilation screen caused electrical arcing and thermal protection trips
A stuck boom holding valve and air ingestion in the pilot line caused jerky movement and uncontrolled drift
A restricted transmission oil cooler and slipping forward clutch caused thermal runaway and fluid degradation
Misaligned lift cylinder anchor pins and stretched anchor bolts caused the inner mast to twist, jamming the rollers
A blocked travel motor bypass valve and worn travel brake seals caused one track to move slower and overheat
A sheared priority valve pin and clogged suction strainer caused simultaneous steering failure and hydraulic lag
A bent lift cylinder rod and dry mast rails caused jerky vertical movement and chain binding
A stuck turbocharger wastegate actuator and clogged air filter caused over-fueling and poor combustion
