คัมมินส์ X15 Parts cover components from nearly every major engine system. Fuel system parts, internal engine components, cooling parts, air system components, wiring, sensors, and control components can all be found across the X15 platform.
The range of Cummins X15 engine parts is broad because the engine combines mechanical, fuel, electrical, and air-management systems in one heavy-duty platform. This guide looks at the main component groups, their roles in the engine, and the X15 parts currently available from YIZHI POWER.


Common Cummins X15 Parts
Fuel System Parts
Fuel system components are central to combustion and engine performance. The X15 parts range includes fuel injectors, fuel pumps, and related wiring.
The X15 อินเจคเตอร์ 4062569, for example, is a diesel fuel injector used within the X15 fuel system. The injector delivers fuel into the combustion process, while the fuel pump supplies fuel to the system.
YIZHI POWER also supplies the ปั๊มน้ำมันเชื้อเพลิง X15 Gear 4088848 และ X15 Fuel Pump Wiring Harness 5491784.
Fuel-system components are closely connected to engine operation, so injector, pump, and electrical components are normally considered as part of the same fuel-delivery system rather than as unrelated items.



Engine Internal Parts
The mechanical structure of the X15 includes pistons, connecting rods, the cylinder block, crankshaft-related components, and other parts that handle combustion and rotational forces.
Available X15 Cummins parts in this area include:
- X15 Engine Piston
- X15 Connecting Rod
- X15 Cylinder Block
- X15 Crankshaft Gear
- X15 Camshaft Thrust Support








Pistons transfer combustion force to the connecting rods, while the crankshaft converts that force into rotational movement. The cylinder block provides the main structure around the cylinders and internal assemblies.
These components become particularly important during major engine repair and rebuilding work, where wear in one part can affect several connected assemblies.
Cooling and Lubrication Parts
The cooling and lubrication systems keep the engine within its intended operating range and provide the conditions required for moving components to work correctly.
YIZHI POWER currently supplies several Cummins X15 replacement parts for these systems, including X15 water pumps, a thermostat, and a lubricating oil pump.
Two X15 water pump references currently available are 5473363 และ 3684449. The X15 thermostat 4336659 is another cooling-system component, while lubricating oil pump 5571595 belongs to the engine’s lubrication system.
The water pump circulates coolant through the engine cooling circuit. The thermostat regulates coolant flow according to engine temperature, while the lubricating oil pump provides the oil circulation required by the engine’s lubrication system.




Air System and Compressor Parts
The X15 air system includes components associated with intake air management and compressed-air supply. One important component is the เครื่องอัดอากาศ X15 4318216. The air compressor is separate from the engine’s turbocharging system and serves the compressed-air requirements of the vehicle or equipment installation.
YIZHI POWER also supplies X15-related control components and wiring used around engine systems. The X15 air compressor has its own repair and replacement considerations, which are covered in more detail in the dedicated คอมเพรสเซอร์อากาศ Cummins X15 article.
Electrical and Control Parts
Modern X15 engines rely on electrical components for sensing, control, communication, and system operation.
The available Cummins X15 engine parts in this category include:
- X15 Wiring Harness 4973486
- ชุดสายไฟโมดูลควบคุม X15 ETR 5486810
- X15 Actuator 4962904
- เซนเซอร์วัดความดันและอุณหภูมิ X15 4921475
- แผ่น X15, เซ็นเซอร์ตำแหน่ง 3694957
- X15 วงแหวนแสดงความเร็ว 3689001






Wiring harnesses connect different electrical components throughout the engine. Sensors provide information used by the engine control system, while actuators carry out controlled mechanical or electronic functions.
Cummins X15 Parts for Repair and Overhaul
Internal engine work may involve pistons, connecting rods, the cylinder block, camshaft-related components, and crankshaft gears. Cooling work may involve the water pump or thermostat, while fuel-system service can involve injectors and fuel-pump components.
The actual parts required depend on the condition of the engine and the scope of the repair. During an overhaul, related components are often inspected together because they operate as connected assemblies.
For example, work on the lower part of the engine may involve the rotating assembly, while upper-engine work can involve valve-train and related components. Cooling, fuel, lubrication, and electrical components can be handled alongside the mechanical work when their condition calls for replacement.
For broader information about rebuilding, YIZHI POWER also has a separate guide covering Cummins Engine Rebuild Kits and the components commonly included in an overhaul.
How to Identify the Correct Cummins X15 Replacement Parts
The most useful details include:
| Information | วัตถุประสงค์ |
| รุ่นเครื่องยนต์ | Identifies the engine family and configuration |
| หมายเลขซีเรียลของเครื่องยนต์ | Identifies the specific engine |
| หมายเลขชิ้นส่วน | Identifies the component reference |
| การสมัคร | Provides installation and equipment context |
| จำนวน | Defines the required supply |
| Photos | Helpful for physical identification |
Cummins X15 Parts or a Complete Engine Assembly?
YIZHI POWER also supplies a Cummins X15 Engine Assembly for applications that require a complete engine rather than individual X15 replacement parts.
A complete engine assembly can be relevant when the existing engine has reached the point where replacing multiple major systems would require extensive repair work. Individual components are more appropriate when the existing engine remains serviceable and the repair is concentrated on specific systems or assemblies.
The X15 Engine Assembly is a separate product from the individual parts listed in this guide and is available for heavy-duty applications requiring a complete 15-liter Cummins engine.
