21343923 Rotor | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta rotor used within a specified pump, generator or rotating engine assembly. The rotor is a precision component whose diameter, vane/profile geometry, shaft interface and running clearance must match the original illustrated assembly; visually similar rotors are not necessarily interchangeable.

⚙️ Key Features

• Genuine Volvo Penta precision rotor
• Position-specific shaft and working-surface geometry
• Controls output within the assigned rotating assembly
• Requires correct running clearance and orientation
• Match component housing, shaft and product serial number
• Engine type: Volvo Penta marine or industrial installation

🔌 Function

Rotates inside the assigned housing to move fluid, generate an electrical field or perform the mechanism's working action.

⚠️ Common Signs of Failure

• Abnormal noise, rubbing or imbalance
• Scoring, corrosion or damaged working surfaces
• Loss of the related pump, generator or rotating-system output
• Excessive clearance or shaft movement
• Cracks, vane damage or looseness on the shaft

🛠️ Service Notes

• At 0.059 kg, confirm which rotating assembly this rotor belongs to (pump, alternator/generator or distributor) before ordering - Volvo Penta lists rotors of similar size and weight across different assemblies and they are not interchangeable between them
• Match the shaft profile, drive slot and running clearance to the housing exactly, and check the product serial number against the parts list - a rotor that looks right but does not index correctly will still fail on assembly

📦 Condition
