FAQ

Q1: Is this injector a direct replacement for the original Caterpillar part on my 320D excavator?
A: Yes, this fuel injector (T409980) is designed as a direct bolt-on replacement for the OEM part. It matches the original dimensions, connector type, and hydraulic specifications, requiring no modifications for installation on the C4.4 engine in your 320D.

Q2: What are the common symptoms of a failing injector that this part would fix?
A: Common signs include poor engine idle (rough running), excessive black smoke from the exhaust, reduced engine power, increased fuel consumption, and difficulty starting. Replacing a faulty injector with this unit will restore proper combustion and engine performance.

Q3: Do you recommend any specific maintenance after installing this injector?
A: Yes. After installation, it is highly recommended to perform a fuel system prime and check for any air leaks. The engine’s ECU should be allowed to perform its automatic injector coding procedure if required. For best results, also replace the fuel filter and ensure the fuel is clean and free of contaminants.
