Q: What performance issues indicate that a ZX120 swing reduction gearbox requires a complete replacement?
A: Clear indicators include an audible grinding noise under the cabin floor whenever the machine rotates, metallic flakes found in the gearbox oil during routine inspections, or the upper house drifting several degrees after the operator releases the controls to neutral.
