A broken tilt-lock valve spring and scored carriage valve spool caused the mast to lurch when lifting heavy loads
A stuck hammer relief valve and cross-contaminated case drain filter caused erratic impact cycles and severe hydraulic heat
A ruptured brake accumulator bladder and degraded fluid caused complete loss of park brake holding power and delayed service braking
A sheared crankshaft key and warped lift pump manifold caused severe fuel starvation under high-load hydraulic cycles
A clogged diesel oxidation catalyst and failed intake throttle valve caused persistent derates and regen failures
Worn steering metering spool and contaminated priority valve caused high-speed shimmy and erratic turn-in
How a broken load-sensing compensator spring and clogged suction filter caused simultaneous lifting failure and hydraulic whining
Diagnosing a sheared coupling spline between the main hydraulic pump and the pilot pump, and a failed compensator valve
A clogged transmission suction strainer and sheared torque converter impeller hub cause sudden loss of drive power
A stuck modulating valve and degraded clutch pack friction material led to violent shifting and premature transmission wear
