3804717 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 3801717, which is the number to quote for the component itself, though that number is not one we list ourselves and would have to be confirmed before the order goes in. The other servo unit core running through this block is 3804747, and nothing published against them 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 3801717, which we do not list ourselves
• Refunded when the old servo unit is returned
• Not separable from the other servo unit cores here, 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 assistance in the control system, turning the demand made at the helm or the lever into the force that moves the unit it drives.

⚠️ 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
• Control heavy, notchy or uneven, with more effort needed than it used to take
• Response delayed, or movement that will not hold the position it is set to
• Whining or groaning from the unit, with fluid weeping around the body or the connections
• A fault reported at the display, or the assistance dropping out and coming back

🛠️ 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 3801717, which is not a number we list ourselves
• Prove the supply, the connections and the linkage before condemning the unit, since a poor connection or a stiff linkage will imitate a failed servo

📦 Condition

• Refundable core deposit - not a physical part
