A failed planetary gear bearing in the swing drive caused metal debris to destroy the output shaft seal
A cracked hydraulic tank baffle and torn suction strainer caused pump cavitation and slow implement response
Seized fuel injector nozzles caused unburnt diesel to wash into the crankcase, diluting the engine oil
A seized main pump regulator and scored swashplate caused internal bypass and excessive hydraulic drag
Water contamination in the shift lever sensor and a damaged wiring harness caused intermittent transmission disengagement
Worn steer axle pivot pins and unbalanced steer tires caused chassis shake at full lock
A loose pump suction line flange and contaminated hydraulic tank breather caused pump cavitation and erratic engine load
Worn torque converter bearing and low transmission oil level caused delayed forward and reverse clutch engagement
A seized steering column bearing and over-tightened orbitrol set screw caused the wheel to freeze during turns
Worn swing motor housing seals and a plugged case drain line caused hydraulic lock and external leakage
