Volvo Penta D3 flexible coupling – 21485410

Volvo Penta D3 flexible coupling 21485410 (also known as damper plate) is an essential part of the engine’s driveline. This coupling absorbs vibrations and provides a smooth connection between the engine and the reverse gear. It helps reduce the load on the driveline, contributing to a longer lifespan of the engine and reverse gear.

Key features and benefits:

• Vibration damping: Absorbs vibrations between the engine and reverse gear for smoother operation.
• Extends lifespan: Reduces wear on the engine and driveline components.
• Essential for driveline: Provides a reliable and efficient connection.
• Specifically for D3 engines: Designed for use with Volvo Penta D3 series engines.

Compatible parts:

Frequently ordered together with the following parts:

• Adapter ring 21429352: The adapter ring is necessary to securely attach the coupling to the reverse gear. This ring ensures a stable and firm connection, which is crucial for the operation of the coupling. View the adapter ring.
• Screw 959230: The screws that securely attach the coupling to the engine and reverse gear. It’s important to maintain or replace this screw when the coupling is replaced. View the screw.
• Water-resistant grease 828250: Essential for lubricating the coupling and other driveline components to reduce wear and improve operation. This grease offers protection against saltwater and corrosion, making it ideal for use in marine environments. View the water-resistant grease.

Associated maintenance parts:

When replacing the flexible coupling, the following parts may be needed to optimally maintain the driveline:

• • O-rings: O-rings are often used in the coupling and other engine connections to prevent leaks. They help seal the coupling, improving engine performance and reducing the risk of damage from leaks. View the O-rings.
