The Daily Maintenance of the Wheel Loader
A loose steering angle sensor and worn bushings caused the EPS (Electronic Power Steering) controller to activate a false safety lockout
A sheared brake release orifice fitting and worn swash plate caused the swing parking brake to drag, creating grinding noise and heat
A stuck load-holding check valve and blocked return filter bypass caused severe hydraulic system instability and thermal failure
A frozen rear axle pivot bearing and mismatched drive tire diameters caused a dangerous loss of lateral stability and unpredictable steering response
A cracked pilot isolation valve housing and worn load check springs caused simultaneous control logic failure and hydraulic instability
A blocked torque converter outlet relief valve and sheared stator support caused a complete loss of power train efficiency in the high-speed range
Air in the hydraulic steering system and a worn steering column U-joint caused resonance and delayed steering response
