Case Study: Hitachi ZX200-3 Accelerator Failure
Problem: The excavator engine speed does not increase when the dial is turned, and error code "Governor Motor Fault" appears.
Solution: Check the Accelerator Motor (Part No. 4257163). In many cases, internal gears are worn. Replacing the motor with our high-quality replacement 4188762 restores full functionality.
Maintenance Tip: For Komatsu PC200, ensure the Float Switch (7861-92-4800) is cleaned every 1000 hours to prevent false low-level alarms.
