21341856 2-Pole Starter SAE1 D4/D6 | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta two-pole SAE1 starting-system component for specified D4 and D6 marine-engine installations. The part belongs to the starter connection/starting assembly and must be matched to flywheel-housing specification, system voltage, pole arrangement and engine serial number; it should not be assumed to be the complete starter motor solely from the abbreviated catalogue title.

⚙️ Key Features

• SAE1 flywheel-housing configuration
• Two-pole electrical arrangement

• fitment within the D4/D6 starting assembly
• Engine type: Volvo Penta D4 inline-four or D6 inline-six common-rail marine diesel

🔌 Function

Forms the specified two-pole electrical/mechanical interface within the starter system so battery current and starter engagement are correctly controlled.

⚠️ Common Signs of Failure

• Starter solenoid clicks but the engine does not crank
• Slow or intermittent cranking with a sound battery and cables
• Excessive current draw, overheating or burnt-terminal smell
• Pinion fails to engage or disengage cleanly
• Internal brush, commutator or bearing wear

🛠️ Service Notes

• Confirm flywheel-housing specification, system voltage and pole arrangement against the engine's serial number before ordering or fitting.
