Volvo Penta flexible coupling – 21373176

Volvo Penta flexible coupling 21373176 is an original flexible coupling used to dampen vibrations between the engine and the reverse gear/drive in Volvo Penta marine engines. This coupling ensures smooth operation of the driveline by absorbing shocks and reduces wear on the engine and transmission. It replaces the older part number 3851964.

Key features and benefits:

Vibration damping: Reduces vibrations between engine and reverse gear for smoother operation.
Extends lifespan: Maintains the integrity of engine and driveline systems by absorbing vibrations.
Replaces 3851964: Suitable as a replacement for the old part number.
Original Volvo Penta part: Ensures a perfect fit and reliable performance.

Compatible parts:

Frequently ordered together with the following parts:

• Flywheel 21517500: The flywheel works with the flexible coupling to transfer engine power to the transmission. It is important to check and replace the flywheel if necessary.
• Gear Ring 3818641 / 21517489: The gear ring is an essential component that transfers engine power to the transmission. It is crucial for driveline operation and should be regularly checked.
• Mounting screws (Flange bolts) 946671: These screws are essential for attaching the flexible coupling to the engine and reverse gear. Be sure to replace these screws when installing the new coupling.

Associated maintenance parts:

When replacing the flexible coupling, the following parts may be needed to ensure proper driveline function:

• O-rings: O-rings provide a reliable seal, prevent leakage, and help the coupling function properly. View the O-rings.
