FAQ

Q1: Is this starter motor a direct bolt-on replacement for my Caterpillar 320D2 excavator?
Yes, this starter motor (428000-9122 / 4823187) is a direct OEM replacement for the C7.1 engine found in the 320D2 excavator. It is designed to bolt directly to the engine block without modifications. We recommend checking your machine’s serial number prefix against our compatibility list for absolute confirmation.

Q2: How do I ensure the correct rotation and voltage for my application?
This starter is a 24V unit with a clockwise rotation (as viewed from the pinion gear end). The C7.1 engine requires a 24V electrical system. You can verify your system voltage by checking the battery bank voltage. If your machine uses a 12V system, this part will not be compatible.

Q3: What is the recommended maintenance for this starter motor to maximize its lifespan?
To ensure longevity, regularly inspect the electrical connections for corrosion and ensure they are tight. Keep the starter motor clean and free from excessive dirt, oil, and hydraulic fluid. If the engine cranks slowly, check battery condition and cable connections first, as a weak battery can damage the starter over time.
