3805379 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 3802379, which is the number to quote for the component itself. It is the only servo unit core line in this run of 60 deposit lines, so there is nothing here to confuse it with.

⚙️ Key Features

• Core deposit line, not a servo unit you can fit
• Belongs with the exchange unit, part number 3802379
• Refunded when the old servo unit is returned
• The only servo unit core line in this run of 60
• 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 that moves the control it is fitted to, following the demand made at the helm or lever.

⚠️ 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
• Heavy or stiff operation, with the assistance falling away as the load rises
• Slow or jerky response, or the control creeping without being asked to move
• Oil weeping from the unit's seals, or the reservoir level dropping
• Whine or groan from the unit, worst at full travel

🛠️ 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 3802379
• Prove the feed pressure, the fluid level and the linkage before condemning the unit, since a tired supply pump or a stiff linkage gives the same complaint

📦 Condition

• Refundable core deposit - not a physical part
