Volvo Penta OEM Flexible Coupling — Part No. 21882313
Genuine Volvo Penta flexible coupling (drive plate / torsional damper) for D4 and D6 marine diesel installations. This coupling transmits engine torque to the marine transmission while absorbing drivetrain vibration and torsional shock — protecting both the engine and gearbox from fatigue loading during normal operation.
Part number 21882313 has been superseded by 23549677, which is the current Volvo Penta ordering number. If your parts lookup already returns 23549677, that is the correct unit to order.

Compatible Applications

- Confirm engine model, serial number, reverse-gear model, and flywheel/primary-shaft assembly before ordering
Serial Number & Configuration Fitment
D4 and D6 engines were produced across multiple transmission, flywheel-housing, and coupling configurations. The correct coupling is determined by the complete drivetrain specification — engine model, serial number, reverse-gear model, and flywheel/primary-shaft assembly — not by engine family alone. Always verify against the applicable Volvo Penta parts diagram for your specific installation before ordering.
When to Replace
Inspect or replace this coupling when you notice any of the following:
- Excessive drivetrain vibration or shudder under load
- Rattling or knocking from the flywheel / transmission area
- Visible deterioration, cracking, or distortion of the flexible elements
- Abnormal rotational play detected during transmission removal
- Damage found during scheduled transmission or flywheel service
Installation Notes
Installation requires access to the flywheel and transmission coupling assembly. While the transmission is removed, inspect the flywheel, transmission input components, mounting hardware, and driveline alignment. Follow Volvo Penta workshop torque and assembly specifications for your engine and transmission combination.

Parts Desk Insights
The most common ordering mistake with this part is selecting it based on engine family (D4 or D6) alone. The correct coupling depends on the full drivetrain configuration — specifically the reverse-gear model (HS45, HS63, or HS80) and the flywheel-housing arrangement. We regularly see customers receive the wrong part because the transmission wasn't confirmed before ordering, which means pulling the transmission a second time. If your catalog lookup is already showing 23549677, order that number — it is the current Volvo Penta replacement. When in doubt, have the engine serial number and transmission model ready before placing the order.
