The Global Search for Quality Engineering Machinery Parts

In the heavy equipment industry, downtime is unacceptable. When a critical component like a CAT Throttle Motor Actuator with part number 191-6840 (or 1916840) fails on your Cat 307B or E308C, you need a reliable, high-quality replacement, fast. This is where Growshine International (格莳国际) steps in. We specialize in the import and export trade of essential Engineering Machinery Accessories, Heavy Truck Parts, Agricultural Machinery Parts, and Auto Parts. Our mission is to connect global clients with dependable Chinese-manufactured alternatives.

Whether you operate Caterpillar, Komatsu, Volvo, Hitachi, or Hyundai machinery, our inventory covers the critical control systems that keep your fleet running efficiently. We understand the specific demands of your equipment, from the precise control required by an Excavator Accelerator Motor for XGMA units (1028007) to the sophisticated electronics in the latest models.

Comprehensive Inventory of Throttle Motors and Actuators

The core of precise engine control lies in the throttle actuator. We stock a wide array of Throttle Control Motors, ensuring seamless operation for various machines. For older CAT models, we offer solutions like the Accelerator Motor for Cat 330C/E325C (247-5209, 2475209, 191-5611, 1915611). For newer generations, the Engine Control Motor for Cat 312D2/E320D2 (386-3439, 3863439) is readily available. Every part is vetted for quality, providing a reliable replacement without the OEM price tag.

Our inventory extends globally, covering essential components such as the Electronic Throttle Motor for Cat E307C/E307D (164-8233, 1648233, 305-5953, 3055953), and the Throttle Motor for Hyundai R220-9 (21en-32340, 21en32340) and R110-7 (21EN-32240, 21EN32240). Specialized parts like the Stepping Motor for Cat E312/E311 Double Cable (41596x) and the Accel Actuator for Kato HD800/HD1250-7 (709-45100006, 70945100006) are also part of our expansive supply chain.

Solenoid Valves and Hydraulic Control Systems

Hydraulic integrity is paramount. Our range of Solenoid Valves ensures your machine's steering, locking, and proportional control functions operate flawlessly. This includes the Caterpillar Proportional Solenoid Valve 111-9916 (or 1119916) and the CAT 320B Safety Lock Solenoid Valve 121-1491. We also provide the Hydraulic Pump Solenoid Valve 1211490 and Solenoid Control Valve 116-3526 for Caterpillar E320 series.

Kobelco and Komatsu operators can rely on us for critical parts like the Pilot Operated Solenoid for SK200-3 (KWE5K-31/G24D40) and the Proportional Solenoid Valve for PC200-6 (702-21-07010, 7022107010). The Green Point Hydraulic Solenoids Valve (YN35V00018F2) for Kobelco SK200-6 is a high-demand item that we consistently stock, reflecting our commitment to sourcing precise Engineering Machinery Accessories.

Precision Sensors, Switches, and Electronic Control Units (ECUs)

Modern heavy equipment relies on thousands of data points provided by Sensors and Switches. Our selection of CAT Speed Sensors, such as the E320D Revolution Speed Sensor 125-2966, and the Excavator Speed Sensor 5I-7579 for CAT 320B/320C, are crucial for optimal performance. Hyundai operators can find various pressure sensors, including the High Pressure Switch 31Q7-40800 and the Hydraulic Pump Low Pressure Sensor 31Q4-40830.

From Komatsu Water Temperature Sensors (7861-92-3320 for PC200-5) to Hitachi Excavator Computer Boards (9116941), we are your single source for electronic components. We supply ECUs for Daewoo DH225-7 (543-00055A) and Volvo D7E Engine Control Unit Modules (60100008), ensuring accurate machine operation. The CAT E320D Pressure Switch 309-5795 is one of many vital components we keep in stock to reduce your fleet's downtime.

Troubleshooting Spotlight: Loss of Power on CAT 320D Excavator

A common issue reported by operators of the CAT 320D Excavator is a sudden loss of power or erratic engine speed. This can often be traced back to a faulty component in the electronic fuel system or a damaged Wiring Harness.

The Failure Scenario and Solution:

The problem often manifests as the machine losing RPMs under load. A frequent culprit is a worn or compromised **C6.4 Engine Wiring Harness** (296-4617, 2964617) or the **Fuel Injection Pump** (326-4635, 3264635, 276-8398, 2768398). If diagnostic codes indicate low fuel rail pressure or injector communication errors, the harness connecting the ECU to the injectors (like the C7/C9 Injector Harness 222-5917 or 235-8202) might have internal breaks or short circuits due to vibration and heat.

Resolution: Always inspect the specific harness segment (e.g., Engine Harness 296-4617) for signs of abrasion or melting. Before replacing the expensive pump, try replacing the relevant injector or sensor wiring harness, such as the Main Harness 3068610. Our comprehensive range of wiring solutions, from the Caterpillar D6R Harness Assembly 109-6379 to the Komatsu PC130-7 Outer Wire Harness 20Y-06-31614, ensures you have the correct, reliable replacement to quickly resolve electrical faults and restore full machine power.

Fuel, Turbo, and Drivetrain Components

Growshine sources high-reliability components covering every system of your machine. This includes robust Fuel Injection Pumps for the Caterpillar 3116 (1307323) and the 320D (326-4635), as well as injectors for Volvo D13 engines (22027808). For performance, our Turbocharger selection is expansive, featuring the Volvo EC300D unit (04299385) and the Caterpillar 320D Turbocharger (287-0049, 2870049).

Our inventory is not limited to heavy excavators; we also cater to Heavy Truck Parts and Agricultural Machinery Parts, ensuring components like alternators (Caterpillar 212-8561 for 320d), gear pumps (Caterpillar M320 281-6269), and specialized components like the Volvo L250G Drive Shaft Actuator (15141094) are available.
