FAQ
Q1: How do I know if my CAT 3412 needs a new fuel injector?
A1: Common symptoms of a failing injector include excessive black or white smoke, increased fuel consumption, loss of engine power, rough idling, and misfiring. A cylinder cut-out test can help isolate the faulty injector.
Q2: Is this a direct “plug-and-play” replacement, or are adjustments needed?
A2: This is a direct replacement part. However, professional installation is highly recommended. After installing new injectors on a 3412 engine, it is critical to check and potentially adjust valve lash and injector height settings as per the engine service manual to ensure optimal performance and avoid damage.
Q3: Do you supply these injectors in sets?
A3: Yes, we typically recommend replacing injectors in sets (especially for cylinders on the same bank) to maintain balanced performance across the engine. We offer single units for testing or spot replacement, as well as complete sets for a full engine overhaul. Contact our sales team for volume pricing.
