  10. Isuzu 4JJ1 Accelerator Motor: Linked to the throttle body. Controls engine speed electronically. Example: Isuzu 4JJ1 Excavator.

Troubleshooting & Maintenance

Case Study: Hydraulic System Weakness on DAEWOO 55

Problem: The excavator arm moves extremely slowly under load, and the engine starts to stall when using full hydraulic pressure.

Diagnosis: Testing revealed that the Main Relief Valve (DAEWOO55) was stuck open due to debris, preventing the system from reaching working pressure.

Solution: Replacing the faulty valve with our premium DAEWOO 55 Main Relief Valve restored full hydraulic power and smooth operation immediately.

Maintenance Tip:

For Caterpillar 320D excavators, always change hydraulic oil every 2000 hours and check relief valve settings every 1000 hours to prevent internal wear on high-precision components.
