Hitachi Equipment Repair in Fontana
Hitachi's ZX excavators are hydraulic machines first — smooth, fast and utterly dependent on healthy pumps, motors and valves. Our Fontana shop repairs Hitachi construction equipment with hydraulics at the center of the work: main pumps, swing and travel motors, control valves and cylinders, plus engines and undercarriage. Independent shop, not a Hitachi dealer — the place owners call when the machine has to dig Monday.

Hitachi work we do every week
Main hydraulic pump diagnosis and rebuild on ZX machines; travel and swing motor service; cylinder resealing and re-rodding; Isuzu-built diesel engine repair (most ZX machines run Isuzu power); final drives and undercarriage; and electrical faults on the monitor-and-sensor systems. Hitachi hydraulics reward precision — pressures and flows are set to spec, not guessed.
