Bulldozer Spare Parts

   SPARKLING MACHINERY NEW 315D 318D 319D 32E61-00022 Injector is a core engine fuel supply component for 3 Caterpillar excavator models (heavy-duty construction/mining use). It precisely atomizes and injects fuel into cylinders, ensuring efficient combustion. 
   The part number 32E61-00022 is for a common rail Fuel Injector used in Caterpillar and Perkins engines and equipment. It cross-references to several other part numbers including 326-4740, 10R-7676, and 295-9140

This fuel injector assembly is used in machinery with the Caterpillar C4.2 diesel engine, including: 
Caterpillar Excavators: 312D, 315D, 318D, 319D, 319D L, 319D LN.
Hyundai Equipment: Used in specific models such as the Hyundai D04FD Robex 140 Excavator.
Engines: Perkins C4.2 diesel engines. 

The Oil Cooler Assembly (Part No. 13C30000-2 / 13C300002) is specially engineered for Doosan and Daewoo excavator models S290LL, S290LC-V, and DH300-5. Designed to deliver efficient heat dissipation, this oil cooler helps maintain optimal hydraulic oil temperature, thereby enhancing the longevity and performance of your machinery.

Manufactured with high-strength aluminum and precision-welded construction, this oil cooler offers excellent thermal conductivity, durability, and resistance to vibration—ideal for demanding construction and forestry environments.

   SPARKLING MACHINERY NEW R80-7 R80-7A 11N1-42120 Oil Cooler is a dedicated thermal management component exclusively designed for R80-7 and R80-7A excavators. As a core part of these excavators’ hydraulic and engine systems, it efficiently dissipates heat from hydraulic oil and engine oil—preventing oil overheating during tasks like small-scale construction, agricultural tillage, and urban infrastructure maintenance. This function is critical for preserving oil viscosity and lubrication performance, which directly protects key components (such as hydraulic pumps, valves, and engine bearings) from premature wear, ensuring stable power output and extending the service life of R80-7/R80-7A excavators.

   Engineered to match original equipment performance standards, it maintains strong heat dissipation efficiency even under harsh working conditions, including high ambient temperatures, dust accumulation, and continuous excavator vibration. It resists oil leakage and internal blockages, avoiding system failures that could lead to unplanned downtime or costly component repairs. Backed by strict performance verification, it guarantees reliable heat exchange to support uninterrupted operation of R80-7 and R80-7A excavators.

Function: This motor is a critical component that converts hydraulic energy into the rotational movement (slewing) of the excavator's cabin and boom assembly.
