3804241 Servo Unit Core | Genuine Volvo Penta Part

🔧 Product Description

Core deposit for an exchange servo unit, listed under the Ignition and Control Systems group. It is the refundable charge raised against the worn servo you return, not the servo itself, and ordering it alone supplies nothing to fit. Under Volvo Penta's core numbering it pairs with part 3801241. No weight is published against this line, and none should be inferred from the other servo core, 3804113.

⚙️ Key Features

• Refundable core deposit, not a fitted part
• Pairs with part 3801241
• Ignition and Control Systems group

🔌 Function

Carries the refundable core charge on an exchange servo unit; the servo it covers provides the hydraulic assistance that moves the drive or steering against load.

⚠️ 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
• Assistance fading or going heavy, particularly towards full lock
• Oil weeping from the servo body or past the shaft seal
• Groaning or whining from the unit as the helm is moved
• Delayed or jerky response, with pressure found below specification on test

🛠️ Service Notes

• The deposit is refunded when the old servo unit is returned; ordering this line on its own supplies no part
• Drain the servo and cap its ports before returning it, so oil does not escape in transit and spoil the core
• Check the pump, hoses and fluid condition before condemning the servo, as a weak supply gives the same symptoms

📦 Condition

• Refundable core deposit - not a physical part
