FAQ

Q: Is this injector a direct fit for my Caterpillar 3116 engine?
A: Yes. This 107-7732 injector is engineered as a direct replacement for the original injector in Caterpillar 3114 and 3116 engines. For optimal results, we recommend replacing injectors in sets and ensuring the engine’s fuel system is clean before installation.

Q: What is included in the packaging, and is it suitable for international resale?
A: The injector is supplied in neutral, non-branded packaging (WX packing), which is standard for the international aftermarket and ideal for distributors and workshops. Each unit is individually packaged to prevent damage during transit.

Q: Do you provide technical support for installation and troubleshooting?
A: Yes. We provide professional service and support. While we supply the part, we recommend that installation and calibration be performed by a qualified diesel technician familiar with common rail systems to ensure proper performance and avoid potential damage.
