Maintenance and Troubleshooting

Fault Case: Excavator Engine Speed Fluctuation

Device: Kobelco SK200-8 Excavator

Symptoms: The engine speed fluctuates irregularly during operation, and the monitor shows an error code related to the throttle system.

Solution: Inspection revealed a worn internal gear in the accelerator motor. Replacing the faulty unit with our Kobelco Accelerator Motor 2406U197F4 restored smooth operation instantly.

Maintenance Tip:

For Caterpillar 320D excavators, ensure the fuel level sensor (Float Switch) is cleaned every 1000 hours to prevent sediment buildup which causes false empty tank warnings.
