🔌 Function

The starter motor engages the flywheel ring gear and cranks the HPDI engine during electric starting. Correct starter speed is important for HPDI engine start-up and ECU-controlled fuel delivery.

Common signs of failure:

• Slow cranking or no crank

• Starter relay clicks but motor does not turn

• Starter pinion slipping or grinding

• HPDI hard-start condition caused by low cranking speed

• High current draw during starting

• Worn brushes, armature, bearings or drive gear

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
