Three Quick Facts on Heavy Equipment Parts:

1. Why does my Komatsu WA380-6 engine overheat? A common cause is a faulty thermostat ( 6754-61-6211 ) or a failing water pump ( 6754-61-1100 ). The thermostat is located in the cooling system and regulates coolant flow, opening fully when the engine reaches operating temperature.
2. How often should I change the pressure sensor on a hydraulic system? While there is no fixed schedule, sensors like the hydraulic pump high-pressure sensor ( 7861-93-1653 ) on a Komatsu WA470-6 should be checked immediately if the machine displays inconsistent pressure readings, as it's vital for system control and safety.
3. What is the function of a solenoid valve in a heavy truck transmission? In heavy truck parts, a gearbox solenoid valve (e.g., 0260120025 ) in a ZF transmission controls the flow of hydraulic fluid to engage or disengage specific clutches, managing gear shifts. A failure can lead to sluggish or missed shifts.

Our expansive product line includes everything from specialized turbocharger gaskets to robust excavator swing motor components. We also specialize in wheel loader axle parts, bulldozer blade systems, and high-performance diesel injector nozzles. For large-scale clients, our bulk supply of engine overhaul kits and filtration media ensures long-term operational efficiency.

Key Component Glossary (Bilingual Examples):

• Alternator (发电机 / Генератор): Converts mechanical energy into electrical energy. Found in the engine compartment. Komatsu Loader 6D105 Alternator.
• Turbocharger (增压器 / Турбокомпрессор): Increases engine power by forcing more air into the combustion chamber. Attached to the exhaust manifold. Komatsu WA380-5 Turbocharger 6743-81-8040.
• Solenoid Valve (电磁阀 / Электромагнитный клапан): An electromechanically operated valve controlling fluid flow in hydraulic or pneumatic systems. Installed in the hydraulic control block. XCMG Loader Gearbox Solenoid Valve 0260120025.
• Pressure Sensor (压力传感器 / Датчик давления): Measures the pressure of fluids or gases. Located in hydraulic lines or engine oil galleries. Komatsu WA380-6 Common Rail Pressure Sensor 6754-72-1210.
• Thermostat (节温器 / Термостат): Regulates engine operating temperature by controlling coolant circulation. Located at the engine coolant outlet. Komatsu Loader 6D102 Thermostat Seal Ring 6732-61-6240.
• Water Pump (水泵 / Водяной насос): Circulates coolant through the engine. Mounted on the engine block. Komatsu WA380-6 Engine Water Pump 6754-61-1100.
• Starter Motor Relay (启动马达继电器 / Реле стартера): A high-current electrical switch used to activate the starter motor. Typically near the battery or starter motor. Komatsu WA380-6 Starter Motor Relay 11Y-06-11391.
• Hydraulic Pump (液压泵 / Гидравлический насос): Converts mechanical power into hydraulic energy (flow and pressure). Mounted to the engine or gearbox PTO. Komatsu Loader WA100 Hydraulic Pump 705-73-29010.
• Crankshaft Oil Seal (曲轴油封 / Сальник коленвала): Prevents oil leakage where the crankshaft passes through the engine block. Located at the front and rear of the crankshaft. Komatsu WA380-6 Front Crankshaft Oil Seal 6754-21-6230.
• Pilot Filter Element (先导滤芯 / Пилотный фильтрующий элемент): Filters the oil in the low-pressure pilot control system of an excavator. Located in the pilot oil circuit line. XCMG Excavator XE210 Pilot Filter Element 803182167.

Common Machinery Fault & Solution:

Equipment: Komatsu Excavator PC200-8

Fault: Intermittent loss of hydraulic power, especially during combined operations (e.g., booming up and swinging). The engine does not stall, but the machine feels "sluggish."

Likely Cause and Solution: This often points to a problem with the main pump pressure sensor or the pump control solenoid valve . On the PC200-8, these components are critical for controlling the main hydraulic pump output (flow and pressure). Check the relevant high-pressure sensor (similar to 7861-93-1653 ) and the PC-EPC solenoid valve . A contaminated hydraulic filter element (similar to 07063-01142 ) can also cause flow restrictions. Action: Replace the pressure sensor first if error codes indicate erratic signals, then replace filters and oil. If the issue persists, inspect the PC-EPC solenoid for electrical continuity and mechanical sticking.
