🔧 Product Highlights

• 4718276 — 8 OEM reference formats covering Isuzu 6UZ1 and 6WG1 engines across 100+ Hitachi ZX / ZAXIS excavator variants from ZX110 compact to ZX870 large mining class and EX1200 — industry-wide coverage for Hitachi dealer and service fleets.
• Failed shuttle valve causes loss of pilot pressure, erratic hydraulic control, and excavator immobilization — direct replacement restores correct hydraulic circuit function and full machine operability.
