Reliable hydraulic control is the backbone of heavy equipment performance. If your excavator is experiencing sluggish response or pump pressure fluctuations, the 086-1879 or 0861879 (also known as 096-4510) solenoid valve is often the critical component requiring attention. As a dedicated heavy-duty parts supplier, we provide high-precision OEM standard replacements designed specifically for the CAT E200B series.

Q1: Why is my CAT E200B hydraulic pump losing power under load?
A: Frequently, the 086-1879 solenoid fails to signal the pump's regulator properly. If the internal coil is burnt or the valve is stuck, the pump stays at minimum displacement, causing power loss.
Q2: Can I use 096-4510 to replace 086-1879?
A: Yes, these are interchangeable part numbers for the E200B auxiliary pump control circuit. Our 086-1879-N (0861879N) is built to cover both specifications perfectly.
Q3: Why Choose This Solenoid Valve?
A: Our valves feature an OEM-standard tri-metal structure and are trusted by repair shops & equipment fleets worldwide for their longevity and stability under high pressure.
