As a factory-direct, source manufacturer, Honour Time Machinery Limited supports custom development and mass production of high-precision engine components, especially cylinder liners. We export globally, ensuring top quality for your machinery.
Welcome to Honour Time Machinery Limited, your reliable partner for premium Chinese high-quality replacement parts for heavy construction machinery. We specialize in engine assemblies and precision components for leading brands including Cummins, Komatsu, Caterpillar, Isuzu, Kubota, Yanmar, and Weichai. Our featured product, the HITACHI Valve Plate 2036786, is engineered to meet or exceed OEM specifications, offering a cost-effective and durable solution for hydraulic pump maintenance on Hitachi excavators.
This Valve Plate, Part Number 2036786, is a critical component in the hydraulic system, ensuring smooth flow and pressure regulation. A worn valve plate is often the root cause of reduced digging power and high oil temperature, common failures in older machinery. By using our domestic high-quality alternative, you directly address these issues, restoring your excavator's performance without the premium cost of genuine parts. We also offer the KOMATSU Float Switch (PN 7861-92-4800 / 7861924800) essential for precise fluid level monitoring in cooling and hydraulic systems.
Use for Excavator Hydraulic System: Specifically designed for Hitachi machinery, ensuring proper fit and hydraulic pressure stability.
Engineered for Durability: The Valve Plate 2036786 is made from high-grade alloy steel for extended service life under extreme pressure.
Fluid Monitoring Accuracy: The Komatsu Float Switch 7861-92-4800 provides accurate readings, preventing damage from low fluid levels.
High-Quality Replacement: Guaranteed compatibility and function as a direct substitute for the OEM part, avoiding common Engine Bearing Failure or Crankshaft Damage due to poor quality.
Wide Application Range: Suitable for various Hitachi excavator models that utilize the 2036786 component.

Common Fault: Engine Overheating During Heavy Load Operation.
Processing Solution: First, check the coolant level using the Komatsu Float Switch 7861-92-4800 to ensure it is not critically low. Inspect the Radiator fins for blockage and test the Water Pump for leakage or reduced flow. If coolant loss is confirmed, replace the Gasket Head and perform a pressure test.
Preventative Maintenance Plan: Change engine oil (using proper viscosity) and filter every 250 hours. Inspect the Fan Cooling Belt tension monthly. Annually, flush the cooling system and replace the thermostat to prevent premature engine component wear, especially the Cylinder Liner and Piston.
