Growshine International, a leading player in the global trade of high-quality spare parts, proudly offers the critical Cummins ISM11 Piston Pin with the part number 4374086. This component is essential for the reliable operation of the Cummins ISM11 engine, widely used in vehicles such as the Shaanxi Auto Delong Heavy Truck (including models like Delong M3000 and Delong F3000). Our commitment at Growshine is to supply durable engine overhaul kits, piston assemblies, and heavy-duty truck components to our global clientele.
The piston pin is a crucial part of the engine's four-package (Four Package) setup, ensuring the proper connection and smooth movement between the piston and the connecting rod. The part number for this precise component is 4374086. We also use the non-hyphenated variant 4374086 in our documentation to maximize search engine visibility. As a specialized import and export company, Growshine International deals in a vast array of engineering machinery accessories, heavy-duty truck spare parts, agricultural machinery spares, and general auto engine parts.

Our dedication to quality ensures the longevity of your Shaanxi Auto Delong and other heavy-duty machinery.
The Piston Pin (4374086) is manufactured from high-strength alloy steel, meticulously heat-treated to resist high loads and wear. It is positioned inside the piston to connect the piston head with the small end of the connecting rod. It must float freely within the piston pin bosses and the connecting rod bushing, allowing the rod to oscillate as the piston moves up and down during the four-stroke cycle. Failure of the Cummins ISM11 piston pin can lead to catastrophic engine damage, highlighting why choosing a high-quality component like the Growshine 4374086 is critical for Shaanxi Auto Delong truck maintenance.
Hydraulic Pump: Converts mechanical power into hydraulic energy (flow and pressure). Mounted on the engine or gearbox PTO. Example: Caterpillar 345D Hydraulic Main Pump.
Turbocharger: A forced induction device that increases an internal combustion engine's power output. Installed on the exhaust manifold. Example: Scania R440 Holset Turbocharger.
Injector: Atomizes fuel and sprays it into the combustion chamber or intake manifold. Installed in the cylinder head. Example: John Deere 9470R Fuel Injector.
Swing Motor: Provides the rotational power for the upper structure of an excavator. Mounted on the excavator's swing reducer. Example: Komatsu PC300-7 Swing Motor.
EGR Valve (Exhaust Gas Recirculation Valve): Controls the flow of exhaust gas into the intake system to lower combustion temperature and reduce NOx emissions. Installed on the exhaust system/intake manifold. Example: Ford F-150 EGR Valve.
Gudgeon Pin (Piston Pin): The pin connecting the piston to the connecting rod. Installed inside the piston bosses. Example: Cummins ISM11 Piston Pin.
Water Pump: Circulates coolant through the engine block and radiator to dissipate heat. Mounted on the engine block/front cover. Example: Volvo FM400 Water Pump.
Final Drive: The last gear reduction unit in the power train, converting rotational power to the tracks/wheels. Located at the track/wheel hub. Example: Hitachi Zaxis 330 Final Drive.
Clutch Pressure Plate: Part of the clutch assembly that applies pressure to the clutch disc to engage the transmission. Located inside the bell housing. Example: Isuzu FVR Truck Clutch Pressure Plate.
Steering Gear Box: Converts the rotational movement of the steering wheel into the linear movement needed to turn the wheels. Mounted on the chassis frame. Example: Mercedes-Benz Actros Steering Gear Box.
Fault: Shaanxi Auto Delong F3000 (Cummins ISM11 Engine) exhibits severe, loud metallic knocking noise, especially when accelerating. This can sometimes be related to components like the piston pin 4374086.
Solution: A persistent, heavy knock often indicates excessive clearance in the connecting rod bearings or the piston pin (gudgeon pin) bore.
Immediately check engine oil pressure and level. Low oil can cause bearing failure.
Conduct a tear-down inspection of the piston and connecting rod assembly.
If the Piston Pin 4374086 or its bushing is worn, replace the pin, the bushing, and potentially the connecting rod and piston if they are also damaged.
Ensure the new Cummins ISM11 piston pin is correctly fitted and lubricated according to manufacturer specifications to prevent premature wear.
