FAQ

Q1: Will this starter motor fit my Cummins 4BT3.9 engine in an excavator?

Yes, this part (3708N-010) is a direct OEM replacement for the 4BT3.9 engine used in excavators like Komatsu PC200-7. Ensure your engine has a 24V electrical system and the starter mounts with an SAE J542 flange. Check your existing part number against our cross-reference list for confirmation.

Q2: What are the signs that my starter motor needs replacement?

Common symptoms include: a clicking sound when turning the key (indicating low power or worn solenoid), slow cranking in cold weather, or intermittent failure to start. If the engine does not crank at all despite a charged battery, the starter motor is likely faulty. Our 4.5kW unit provides the necessary torque for reliable starts.

Q3: How do I maintain this starter motor for longer life?

Ensure the electrical connections (battery cables and solenoid terminals) are clean and tight. Avoid prolonged cranking (more than 15 seconds) to prevent overheating. Periodically check the mounting bolts for tightness and inspect the drive gear for wear. In harsh environments, consider using a starter motor cover for added protection.
