381200426 XCMG GR2605 motor grader solenoid valve mounting plate

381200426 XCMG GR2605 motor grader solenoid valve mounting plate

381200426 is a genuine XCMG GR2605 motor grader solenoid valve mounting plate (manifold). It integrates and secures multiple hydraulic solenoid valves, providing a hydraulic circuit manifold and installation reference, ensuring valve assembly connection sealing, precise operation, and convenient maintenance.

Core Functions and Benefits

Valve Assembly Integration and Fixing: Precisely positions and secures the solenoid valve body, preventing valve block displacement and interface loosening/leakage caused by operational vibration.

Centralized Hydraulic Circuit Manifold: Built-in hydraulic circuit channels enable centralized distribution of inlet, return, and control oil, reducing redundant piping and minimizing leakage points.

Installation Reference and Sealing: Original factory standard sealing surface + locating pin, and matching sealing gasket ensure reliable sealing under high-pressure conditions, preventing hydraulic oil leakage.

Simplified Inspection and Maintenance: Organizes the valve assembly layout, facilitating quick disassembly and assembly of solenoid valves, pressure testing, and troubleshooting of hydraulic circuit faults.

Key Technical Parameters

Model: 381200426
Name: Solenoid Valve Mounting Plate (Manifold)
Compatible Model: XCMG GR2605 Grader
Material: High-strength cast aluminum/alloy steel, surface anti-corrosion treatment
Features: Original factory dimensional accuracy, standard oil passage diameter, smooth sealing surface, precise positioning, pressure resistant and vibration resistant

Replacement and Maintenance Points

Before installation, thoroughly clean the sealing surface and oil passage holes to remove oil, metal shavings, and strictly prevent impurities from entering the system.

A brand new sealing gasket must be replaced. Tighten the bolts evenly and crosswise according to the original factory specified torque to avoid uneven force leading to seal failure.

After installation, test the machine under no-load to check for leaks and whether the solenoid valve operates normally; routinely inspect the tightness and periodically clean surface oil and dust.
