FAQ

Q: Will this starter motor fit my Mitsubishi 6D22 engine?
A: Yes, it is a direct bolt-on replacement for 6D22 and D6AC engines. Ensure your current starter uses a 13-tooth pinion and 24V system. Verify mounting flange dimensions with your old unit—most SAE J542 flanges are compatible.

Q: What is the difference between this 5.5kW starter and a lower-power unit?
A: The 5.5kW output provides higher cranking torque, essential for cold starts in large displacement diesel engines (6D22 is ~6.5L). Lower power starters may struggle in cold weather or with high-compression engines, leading to slower start times.

Q: How do I maintain this starter motor for long service life?
A: Keep electrical connections clean and tight. Check battery voltage (minimum 24V under load). Inspect drive gear for wear every 500 hours. If the starter engages but engine fails to crank, test the solenoid and battery cables first—these are common failure points, not the motor itself.
