FAQ

Q: Is this starter motor a direct fit for my Cummins NTA855 generator?
A: This starter (P/N 3021036) is the standard OEM specification for the NTA855 engine. However, we always recommend comparing the physical dimensions (mounting bolt pattern, nose cone length) and the number of teeth on the drive gear to your existing unit. Variations can occur between different generator set configurations (e.g., Cummins vs. other power generation packages).

Q: What is the difference between a new starter and a remanufactured one for the NTA855?
A: A new starter, like this one, contains all brand-new internal components (armature, solenoid, brushes, bearings). This typically offers a longer service life and higher reliability. A remanufactured starter uses a salvaged core that is rebuilt with new wear parts. For critical marine or prime power applications, a new starter is often the preferred choice to minimize downtime.

Q: How should I maintain this starter motor to ensure a long service life?
A: Proper installation is key. Ensure all electrical connections (battery cables, solenoid terminals) are clean and tight. Regularly check the mounting bolts for security, as vibration can loosen them. Avoid prolonged cranking cycles (e.g., more than 30 seconds on, followed by a 2-minute cool-down) to prevent overheating. Keeping the starter clean and dry will also help protect it from corrosion and debris.
