A scored reverse clutch piston seal and blocked hydraulic cooler caused a “stall-at-stall” condition linked to torque converter back-pressure
A bent steer axle pivot pin and incorrect toe-in alignment caused the rear wheels to fight each other, leading to instability and tire scrubbing
Loose track adjuster yoke bolts allowed the recoil spring to shift, causing the track frame to impact the chassis during swing operations
An incorrectly adjusted brake pedal height prevented the transmission cut-off valve from releasing, keeping the machine in a permanent neutral state
A clogged vaporizer hose and lean fuel mixture caused the engine to starve when the mast was raised under full load
A blocked regeneration valve and scored main spool caused flow restriction and pressure loss during boom lowering operations
A sheared impeller hub key and worn clutch plates caused complete loss of high-range drive, requiring transmission teardown and seal replacement
A faulty proportional lowering valve and worn lift cylinder seals caused uncontrolled descent speed and dangerous load oscillation
A broken regeneration check valve spring and scored main spool caused cavitation during boom lowering and loss of speed in arm-in function
A seized priority flow control valve and air-bound steering cylinder caused inconsistent pilot pressure and loss of directional control
