The c-aterpillar 138-8756 injector is a high-precision, heavy-duty fuel injection core component exclusively designed for c-aterpillar 3412 series engines, including 3412C, 3412E, 3412TA and 3412D models. It adopts upgraded Electronic Unit Injection (EUI) technology and adheres strictly to c-aterpillar’s original manufacturing standards, integrating high-strength wear-resistant materials and enhanced sealing structure. Specifically tailored to the high-load, high-pressure and harsh working environments of 3412 series engines, this injector delivers exceptional injection precision, superior durability and efficient fuel economy. It enables direct replacement of original parts, rapidly restores engine power, reduces maintenance frequency, and provides long-term stable operation support for all heavy-duty equipment equipped with 3412 engines.

Core Parameters & Compatibility

Parameter Item	Specific Specific-ations	Core Value
Applicable Engine Models	c-aterpillar 3412C, 3412E, 3412TA, 3412D	100% OEM-compatible, perfectly matching the original engine’s injection system without any modific-ation, avoiding power instability, difficult startup and fuel leakage caused by mismatched injectors.
Injection Technology	Upgraded Electronic Unit Injection (EUI) Technology	Achieves more precise control of injection timing, fuel volume and pressure, supports three-stage injection (pre-injection + main injection + post-injection), optimizes combustion efficiency and ensures stable engine power output.
Product Material	Tungsten carbide precision nozzle, high-strength alloy plunger, titanium-plated anti-corrosion surface (Hardness: HRC73-75)	Significantly enhances wear resistance, high-temperature resistance and corrosion resistance, effectively preventing nozzle wear, carbon deposition and needle valve jamming, extending the injector’s service life.
Replacement Part Numbers	138-8754, 10R-1267, 20R-0758, 178-0199	Cross-compatible with multiple related injector models, facilitating spare parts procurement and reducing inventory pressure for users.
Warranty Period	15 months (New Parts); 12 months (Remanufactured Parts, Unlimited Working Hours)	Covers all quality-related issues, including injection pressure deviation, component damage and needle valve jamming, providing professional after-sales technical support.

Core Performance Features

Performance Aspect	Technical Details	Product Advantages
High-Precision Injection	8-hole precision nozzle, injection error ≤ ±0.8%, maximum injection pressure: 2000bar	Ensures uniform fuel atomization and full combustion, reducing carbon deposition by 20%, improving engine efficiency and reducing exhaust emissions.
Super Durability	IP68 protection grade, 210 million injection cycles endurance, operating temperature: -40℃ to 150℃	Adapts to harsh working environments such as high dust, high humidity and extreme temperature, service life up to 8200 working hours.
Energy Saving & Emission Reduction	Solenoid valve response time ≤ 0.08ms, intelligent closed-loop fuel control system	Reduces fuel consumption by 13%-16%, meets Euro V emission standards, significantly lowering long-term operation costs.
Easy Installation & Maintenance	OEM standard size, net weight: 2.2kg, installation time ≤ 18 minutes, detachable nozzle for easy cleaning and maintenance	Direct replacement without modifying the engine, reducing equipment downtime and simplifying daily maintenance work.
