3805425 Servo Unit Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for a servo unit, in the Ignition and Control Systems group. It is the refundable charge raised against the old servo unit when the exchange unit is bought, and it comes back once the worn servo unit is returned. The line itself is an accounting entry rather than a part, so nothing ships against it on its own. Under Volvo Penta's core numbering the exchange unit it belongs to takes part number 3802425, which is the number to quote for the component itself. It is the sixth servo unit core listed here and the only one outside the run 3805380 to 3805384; nothing published against the six separates one from another, so order the number that matches the servo unit actually coming off.

⚙️ Key Features

• Core deposit line, not a servo unit you can fit
• Belongs with the exchange unit, part number 3802425
• Refunded when the old servo unit is returned
• The one servo unit core outside the 3805380 to 3805384 run, so order by part number
• Ignition and Control Systems group

🔌 Function

As a line item it carries the refundable core charge on the exchange; the servo unit itself provides the powered movement that positions the control it drives, following the demand sent to it from the helm.

⚠️ Common Signs of Failure

• This is a deposit line and has nothing to fail in itself; the signs below are what normally condemns the servo unit being exchanged
• Steering or control going heavy, slow or losing its assistance altogether
• The unit whining, buzzing or running hot whenever it is asked to move
• Movement lagging behind the helm, or overshooting and hunting around the position demanded
• Servo fault codes that come straight back after the supply, earths and connectors have been proved

🛠️ Service Notes

• The charge is refunded when the worn servo unit is returned, so keep the old unit and send it back rather than scrapping it
• Ordering this number on its own supplies no part - it goes on the order beside the exchange unit, part number 3802425
• Prove the supply, the earths, the connector pins and the linkage the unit drives before condemning the servo itself

📦 Condition

• Refundable core deposit - not a physical part
