We specialize in the import and export trade of high-quality spare parts across four major sectors: engineering machinery parts, heavy truck parts, agricultural machinery parts, and auto parts. Our expertise ensures you receive components, from delicate Injector Nozzles to robust Cylinder Liners, that meet rigorous specifications. By choosing Growshine, you gain access to a quality-controlled supply chain that drastically reduces your maintenance costs without compromising machine uptime.
CAT and OEM Equivalent Component Sourcing Simplified
The core of successful heavy equipment operation lies in the quality of its components. Our inventory focuses heavily on key equipment like CAT Excavators (320D, 336D, 345D) and associated engine series (C6.4, C7, C9, C13). We meticulously manage part identification, providing not only the standard part number (e.g., SE91AA/3M or 360-9273) but also the simplified number (e.g., SE91AA3M or 3609273) to ensure flawless ordering and cross-referencing. Below, you will find a comprehensive list of critical parts, including everything from Engine Oil Filters (43249096) and Piston Assemblies (SE901BA) to specialized Hydraulic Oil Filters (179-9806) and Undercarriage Components (370-4381). Trust Growshine to deliver precision components directly to your warehouse.
Tech Insight: Troubleshooting Low Power on a CAT 320D C6.4 Excavator
A common issue in the CAT 320D Excavator equipped with the C6.4 engine is unexpected low power or excessive black smoke. Often, this problem is directly related to a failing Injector Assembly (T402742R) or a clogged Air Filter Element (SEV551/42).
Fault: Significant power loss under load on a CAT 320D.
Detailed Solution:
First, check the Air Filter Element SEV551/42. A restricted air supply drastically reduces combustion efficiency.
Inspect the Fuel Check Valve (860/334) and Diesel Filter (47592051) for clogging or failure, which starves the high-pressure fuel pump 319-0677.
If filtration is fine, the issue may be electronic or injector-related. Monitor the Fuel Pressure Sensor (266-0136). If the pressure is low, the High Pressure Fuel Pump (319-0677) may be failing.
Finally, a faulty Piston Ring (359/552) or a worn Cylinder Liner (SE7E/21) can cause compression loss, leading to low power. A complete engine overhaul using our high-quality Upper (12SE663W) and Lower (12SE663U) Gasket Sets might be necessary for a full restoration.
